Offline Time Tracker
Track time anywhere — no internet required
Most time trackers treat offline as a queue: you can track without a connection, but the entries sit on the device until they reach the vendor's server, and the vendors' own docs warn against logging out before that happens. TickTappy is offline-first: your timer runs locally, your data is stored on your device, and nothing requires a server. Works on planes, in basements, in rural areas, or anywhere you don't have signal. When you want sync, you can optionally enable it.
What "works offline" means in practice
There are three layers to an offline claim, and most apps only clear the first. The first is that the running timer keeps counting without a connection, which almost everything does because a timer is just a start timestamp. The second is that a stopped entry is saved somewhere durable on the device rather than held in memory until it can be uploaded. The third is that you can read your history and totals while still offline.
TickTappy clears all three because the local database is the app's only required storage. Starting, stopping, adjusting, deleting, grouping tags and reading the day and week summaries all happen against the copy on your device. The cloud, if you enable it, is a mirror of that copy, never the thing the app waits on.
How TickTappy stores your time
On iPhone, iPad, Android and Mac, entries are written to a database in the app's own storage the moment you tap. On the web the same happens in your browser's local storage, which is why the web app at ticktappy.com keeps working with the network cable pulled. Nothing about the write depends on a server, and there is no account to be logged out of.
Premium sync adds a second copy in your account so your other devices can pull it. When a device has been offline, it sends the entries it recorded and receives the ones it missed; the device that recorded an entry remains its source. Turn sync off and the app is exactly the same app with one fewer background job.
Where offline-first earns its keep
Long flights, where a queued entry can wait ten hours to sync and a forced logout on landing can lose it. Field and site work in buildings that eat signal, where the connection drops mid-shift. Metered or roaming data, where you would rather nothing uploaded at all until you are home. And ordinary rural or basement coverage, where an app that shows a spinner instead of your history is an app you stop opening.
The common thread is that the moment you most need to record time is often the moment you have the least connectivity. A tracker that treats the device as the record works the same in all of these; a tracker that treats the device as a buffer works until the buffer fails.
Check any tracker's offline claim in five minutes
Turn on airplane mode. Start a timer, wait a minute, stop it. Force-quit the app and reopen it: the entry should still be there with the right duration, and yesterday's history should still load. Then reconnect and confirm the entry did not duplicate or vanish. Most marketing pages say offline; this test says which layer they mean. The guide to tracking time without internet on this site walks through the same check with more detail.

FAQ
What is the best time tracker that works offline?
TickTappy is built offline-first. All data stays on your device by default, timers run without internet, and there's no account required. Toggl, Clockify and Harvest's mobile apps do track offline too, but they hold the entries locally until they reach a server — and Toggl's and Clockify's own docs warn that logging out before that happens can lose them. With TickTappy there is no sync step to fail.
Can I track time without internet on TickTappy?
Yes. TickTappy works 100% offline. Start timers, stop timers, view history, see summaries — all without internet. Your data is stored locally. Cloud sync is an optional Premium feature.
Which time trackers work without an internet connection?
More than you might expect: TickTappy, ATracker and HoursTracker, and also Toggl Track, Clockify and Harvest's mobile apps. The difference is where the risk sits. The cloud tools queue offline entries until they can reach a server; TickTappy is offline-first by design and never needs one.
