How it works

  1. 1

    Add a place

    Pick it on the map, set a radius and a goal.

  2. 2

    Allow location once

    So Android can tell Locitime when you arrive or leave.

  3. 3

    Forget about it

    Arrivals and departures are logged in the background.

Where it helps

Real situations Locitime is made for.

Hybrid work & coworking

Know exactly which days you were at the office or the coworking space. Set a goal like 3 days a week and see whether you meet your company's policy or your own plan.

Gym & habits

Set a goal like 3 gym visits a week. Locitime logs every visit on its own and keeps your streak, so you can see if you are on track without checking in.

Records for clients & billing

Export a PDF or CSV of the days and hours you spent at a client site, or a signed summary that anyone can check has not been altered on this website. It lists arrivals and departures only, never your route.

Daily or weekly goals

Set a daily goal or days per week. Short visits add up: a day counts once your total time at the place reaches your goal, even if you came and went a few times.

Privacy and proof

Your data stays on your phone.

  • A record you can share. Need to show your visits to someone? Share a signed summary as a PDF. Anyone can check it was not altered, and it holds only arrivals and departures, never your route. It does not prove you were physically at a place. Verify a proof →
  • No account, no in-app analytics. Places and visits are stored only on this phone.
  • Network only for the map and address search, and only after you allow it.
  • Geofencing uses Google Play Services on your phone, without continuous GPS.
Read the privacy policy →

Technical details
  • Signed proof: ECDSA P-256 signature over a SHA-256 Merkle root of your visits. The key is kept in the Android Keystore (TEE or StrongBox where the phone has it).
  • Encrypted backup: AES-256-GCM vault (.locitime), key derived by PBKDF2.
  • Export: CSV, PDF, JSON.
  • Wipe: Erase everything, including the signing key, by holding a button for 3 seconds.

Frequently asked questions

Clear answers about goals, battery and your data.

What is a goal day?

Every place has its own goal, for example 2 hours. Locitime adds up all your visits to that place during the day, and the day counts as soon as the total reaches the goal. Time at different places is never mixed together.

Can I track days per week?

Yes. Each place can use a daily goal or a days-per-week goal, where any days count. You can also choose which weekdays are active.

Does background geofencing drain my battery?

Very little. Locitime asks Android to watch the edge of each place through Google Play Services, so the app does not keep GPS running in the background. While a visit is open it also re-checks every 15 minutes that you are still there, using your paired Wi-Fi or beacon if you set one up, or a single quick location check if not.

What permissions does Locitime require and why?

Precise and background location, so Android can tell Locitime when you arrive or leave while the app is closed. Notifications, for goal reached, tracking paused and backup reminders. Wi-Fi state and Bluetooth scan, only if you turn on Wi-Fi or beacon backup for a place. Internet, only for map tiles, address search and the weekly update check, after you allow them. Read the full privacy policy.

Does an employer or client see my location?

No. Locitime has no server and no account. It only stores arrival and departure times at the places you add. It does not store routes or a location track between places. You decide what to share: a CSV, a PDF or a signed proof.

What happens if I switch or lose my phone?

Your history lives only on the phone. Export an encrypted vault (.locitime) protected by a passphrase, keep it where you choose, and restore it on the new phone during setup. Nobody can recover a forgotten passphrase.

How do I delete my data?

In Settings you can edit or delete a place, reset the current month, or wipe everything. Wipe also deletes the signing key. Removing the app deletes your history too, so save a backup first.

Is Locitime free?

Yes. Locitime is free, with no ads, no subscription, no in-app purchase and no analytics SDK.

Take control of your time and places.

No account required. Free, private, and lightweight on Android.

How to install the APK · Verify your download

Available via direct APK. Coming soon to Google Play Store.

How to install the APK

  1. Download. Open this page on your phone and tap Download APK. If the browser says the file might be harmful, tap Download anyway.
  2. Allow the install. Open the downloaded file. If Android says your browser is not allowed to install apps, tap Settings and turn on Allow from this source.
  3. Install. Go back and tap Install. If Play Protect asks, choose Install anyway.
  4. Open Locitime. Add your first place and allow location when asked.

Android shows a standard warning for any app installed outside Google Play. Locitime has no ads and no trackers, needs no account, and keeps your data on your phone. You can check the file with Verify your download.

Locitime is in beta. On some phones Android can limit background location, and a visit may be missed. If something looks wrong, tell us with Get in touch in About.

User guide

How to use Locitime, from the first launch to your exports.

Get started

Open Locitime and tap Continue to Setup. Locitime needs your location all the time, so choose Allow all the time when Android asks. This is how Android tells the app that you arrived or left while it is closed.

Allow notifications if you want to hear when a day reaches your goal. If Android offers Pause if unused, turn it off for Locitime, or Android may remove the permission after a while.

Reinstalling? Pick Restore from backup in the setup to bring back your places and history.

Add a place

On Home, tap the Add place button. Choose the spot with the map, or search for an address. Both are optional and ask for your consent first, because they use the network: the map loads tiles from OpenFreeMap, and the search sends your text to OpenStreetMap.

Give the place a name, or pick a quick start such as Office or Gym. Set the detection radius (50 to 500 m; 100 m is recommended, because a smaller one can miss arrivals). Set the daily goal: the time you need to spend there for the day to count. The default is 2 hours.

Choose the schedule. With Specific days, only the days you pick count towards your goal. With Days per week, any days count, as long as you reach that number each week. Visits on other days are still recorded. Tap Save place.

How a day counts

After setup you do nothing. Locitime logs a visit when you arrive and closes it when you leave, and keeps a running total for each place during the day. Stepping out and coming back, for lunch say, does not reset anything. When a place's total reaches its goal, that day is marked as reached. Time at different places is not added together.

When GPS is weak indoors

In the place settings you can turn on Wi-Fi & Bluetooth backup. While you are at the place, tap Pair current Wi-Fi to pair its network, or Pair a nearby beacon for an iBeacon or Eddystone tag. Locitime then also notices you through that signal. The signal is only compared on your phone. There is also a master switch for the backup in Settings.

Home

Home shows today at a glance: the time you have spent, your goal, and whether the day reached its goal. Under it you find your current streak, this month's progress, the This week card, and today's visits. Once you have more than one place, a row of buttons lets you look at All places or at one place.

History and day detail

History is a calendar of your month. The calendar marks goal days, partial days that fell short, and rest or untracked days. Tap a day to see its visits, then View the full day timeline for the times, how each visit was detected, and the gaps between visits. There you can also export a signed record of that day.

Settings

In Settings you can edit, pause or delete each place. A paused place detects nothing, but keeps its past visits. You can also set one daily limit for all places, check the permissions, and turn on the weekly update check, and reach export, backup and the signed record.

Export and backup

Under Export, choose a date range and save a CSV spreadsheet, a PDF report, a full backup (JSON) or an encrypted backup (.locitime). You choose where the file goes, and Locitime never uploads it. For an encrypted backup you set a passphrase: if you forget it, nobody can open the file.

Your history lives only on your phone, and removing the app deletes it. Save a backup now and then. Locitime reminds you after a month. To bring a backup back, use Restore from backup.

Share a signed record

In Settings, open the signed record. Locitime signs a summary of your visits with a key kept on your phone. Share it as a QR code, a JSON file or a PDF. Anyone can check it offline with Verify a proof on this website, and it shows whether the proof came from an official Locitime build. The check confirms the record was not changed. It does not show that you were at the places.

If something does not work

Home says Tracking is paused: tap Review and set location to Allow all the time. Android may have taken the permission back.

Arrivals are missed indoors: use a radius of at least 100 m and pair the Wi-Fi or a beacon.

A day does not count: check the place's schedule and goal, and remember that days outside the schedule are recorded but not counted.

Anything else: use Get in touch in About.

Changelog

What changed in each version.

0.2.17 · 7 Oct 2026

  • New: Notifications when you arrive at and leave a tracked place. The departure one also shows your total time there today. They have their own channel, so you can mute them separately.

0.2.16 · 7 Oct 2026

  • Improved: Settings is easier to scan: "Permissions & Settings" now sits right after your places, and "Device Signing Key" sits just above the purge card.

0.2.15 · 6 Oct 2026

  • New: A new Settings option, "Follow my current place": the Dashboard selects the place you are at and returns to your default place when you leave.

0.2.14 · 6 Oct 2026

  • Improved: The tracking journal on your phone now keeps the last 14 days, so you can see how tracking behaved over that whole window.

0.2.13 · 6 Oct 2026

  • Fixed: If arrival is missed, the check that runs about every 15 minutes now opens the visit when your location is inside the place, even when indoor accuracy is poor.
  • Improved: The app keeps a small tracking journal on your phone, so an unexpected visit can be explained afterwards. It never leaves your device.

0.2.12 · 6 Oct 2026

  • Fixed: Wi-Fi backup now recognises every access point of the paired network, so arriving at a site with several access points opens the visit.
  • Fixed: If the arrival is detected late or missed, the check that runs about every 15 minutes now opens the visit once you are clearly inside the place.

0.2.11 · 5 Oct 2026

  • Improved: The Home filter no longer has an "All Places" option, so it always shows one place. With more than one active place, you can choose in Settings which one opens by default.
  • Fixed: In History, the day title no longer wraps onto two lines in Greek, and the "Today" tag no longer sits tight against the date.

0.2.10 · 4 Oct 2026

  • Fixed: In longer languages such as Greek, the month progress on Home no longer wraps onto two lines.

0.2.9 · 4 Oct 2026

  • Improved: With several places, the Today card now names the other places you were at today ("Also today: …"), and Visits Today counts only the place shown on the card.

0.2.8 · 4 Oct 2026

  • New: An optional update check. Turn it on in Settings and, once a week, Locitime reads a small public file from locitime.app and tells you when a newer version is ready. It is off by default, sends nothing about you, and never installs anything by itself.

0.2.7 · 4 Oct 2026

  • Improved: The privacy text and the info dialog in the app now say Signed record too.

0.2.6 · 4 Oct 2026

  • Improved: Clearer wording in the app: a day that reaches your goal is now called a goal day, and the Integrity Proof is now called a Signed record.

0.2.5 · 3 Oct 2026

  • New: The This week card now also appears when you choose specific days, and it names your goal underneath, for example "Goal: Every day".

0.2.4 · 3 Oct 2026

  • Fixed: The timer no longer freezes when you stay at a place all day. Locitime now checks every 15 minutes that you are still there, and closes the visit if you have left.
  • Fixed: A visit that ends at midnight showed a negative time in History. It now shows its real length.
  • Fixed: The time on the Home card is no longer cut off in Greek.
  • Fixed: The monthly goal no longer counts today as missed before the day is over.

0.2.3 · 2 Oct 2026

  • Fixed: When your Wi-Fi reaches past the edge of a place, leaving no longer keeps the visit open. It now ends once the signal is gone.
  • Improved: Clearer explanations of the iBeacon and Eddystone formats when you pair a beacon.

Verify your download

Locitime is installed from a file, so check it first. The file must match the values below. If it does not, do not install it.

How to check

The checksum proves the file was not changed on the way. The certificate proves it was signed with the Locitime release key. We use SHA-256 because MD5 is no longer safe for this.

Locitime is in beta. On some phones Android can limit background location, and a visit may be missed. If something looks wrong, tell us with Get in touch in About.

About Locitime

Locitime is made by Stavros Lamprou, an independent creator, not a company.

The idea is simple: a quiet tool that keeps a private record of the time you spend at the places that matter to you, without handing your location to anyone. It needs no account, shows no ads and has no analytics. Nothing leaves your phone unless you export it yourself.

Because it is a one-person project, there is no technical support, no sales team and no data to sell. Updates arrive when they are ready, and your feedback helps decide what comes next.

Privacy Policy

Last updated: 4 October 2026 · Open as a page

Locitime has no account and no server of its own. This page says what the app does with your data and what you control.

What Locitime records

When you arrive at or leave a place you added, Locitime stores the place, the arrival and departure times, and how the visit was detected. It uses them to work out your goal days. Your settings are stored too.

Where it is kept

Only in this phone. There is no Locitime server, no account, no analytics, no advertising and no tracking library. Nothing is uploaded unless you save a file yourself.

Location and nearby signals

Locitime asks for precise location and for Allow all the time, so Android can tell it about arrivals while the app is closed. The geofencing itself is provided by Google Play services on your phone; Google's own privacy terms apply to that part. If you turn on Wi-Fi or Bluetooth backup for a place, Locitime compares the Wi-Fi network or beacon around you with the one you paired. That comparison happens on the phone and the names are never uploaded.

When the network is used

The optional map in Add Location downloads map tiles from OpenFreeMap, which is built on OpenStreetMap. That server can see your IP address and the map area you look at. The optional address search, when you press Search, sends the text you typed, your IP address and the app language to the Nominatim service of OpenStreetMap. The optional update check, once a week, reads the public file latest.json from locitime.app. That website can see your IP address and the time of the request, and nothing about you or your places is sent. The map, the search and the update check are all off until you allow them, and you can turn the map off again from the map. Locitime sends nothing else over the network.

Files you create

CSV, PDF, JSON backups, encrypted vaults and signed records are saved where you choose. Locitime never uploads them. A plain JSON backup can be read by anyone who has the file; a vault needs its passphrase, and nobody can recover a forgotten one.

Signed records

A signed record is a summary of your visits signed with a key kept in this phone's Keystore. It contains your totals, place names and the public part of that key, so anyone you give it to can tell that two signed records came from the same phone. It does not prove that you were at a place.

Your control

You can edit or delete any place, reset the current month, or delete everything, which also deletes the signing key. You can take back location, notification and nearby-device permissions in Android settings at any time; tracking then pauses.

Reinstalling

Your history lives only on this phone, so removing the app deletes it. Save a backup first if you want to keep it.

The website

The locitime.app website, not the app, counts visits with GoatCounter, a privacy-friendly service. It sets no cookies and does not follow you across sites. It records the page visited, the referrer, the browser and screen size, and the country, without storing your IP address. The app does none of this.

Children

Locitime is not directed at children and does not knowingly collect data from anyone, because it collects nothing off the phone.

Changes to this policy

If Locitime starts using the network for anything else, or handles data differently, this page and the app's Privacy screen will change before the update ships. The date at the top shows the last change.
