QS Logs

Track habits, moods and ratings with a single tap.

🔒 No internet access. No account. No tracking.
Get it on Google Play Free. Android 7.0 and later.

What you can track

You build the screen yourself out of tiles. Name them, colour them, set their scales, and drag them into whatever order suits your day.

+

Counters

Tap to record that something happened. Glasses of water, coffees, walks — anything you want a number for.

⇄

States

Pick from your own list of options. Energy: High, Steady, Low. Anything with a small set of named values.

★

Ratings

A slider on your own scale. Mood out of 10, sleep quality out of five. Whatever you actually want to measure.

See what actually happened

Switch the whole app between a day, a week, a month or a year and step backwards through time. Every entry is listed newest first, and anything logged by mistake comes out in a tap. Logging late is normal, so you can backdate an entry by up to 24 hours.

Your data stays yours

This is the part most trackers get wrong, so it is worth being precise:

  • The app has no internet permission. Not “we promise not to upload” — it cannot. You can check the permission list yourself, on Google Play or in Android's settings.
  • No account, no sign-in. The app never asks who you are.
  • No analytics, telemetry, crash reporting or advertising, and no third-party SDKs of any kind.
  • Android's automatic backup is switched off, so your logs are not quietly copied to Google or to your next phone.

Backups you control

Nothing is backed up unless you ask for it, and it goes exactly where you put it.

Full backup

Export everything as a .json file and import it back whenever you like.

Encrypted, if you want

Protect a backup with a password and it is encrypted with AES-256-GCM. Nobody without that password can read it — including us, because we never see it.

Spreadsheet export

Export entries as .csv to chart them elsewhere. CSV is never encrypted, because other software has to be able to open it.
