A workout log that works offline, with no account.

As of 14 November 2026.

Quietlift keeps your training log on your phone, in an encrypted database, and asks for no account: there is no server to sign up to. Everything works in airplane mode; only buying or restoring Pro needs a connection to the App Store or Google Play.

What works without a connection

• Logging a workout, with last time’s numbers on every set, the rest timer on the Lock Screen, records found as you lift.
• Routines, the exercise library (508 exercises, named in five languages), custom exercises.
• Progress: the chart per exercise, estimated 1RM, the body map, the reports.
• Timers, the 1RM table, the unit converter, the metronome, the body-weight log, the widget.
• Export to CSV, JSON or Markdown, backup and restore.

What needs a connection: buying Pro, restoring a purchase, and nothing else. On Android the app does not even request the internet permission; the only network traffic is Google Play’s own, when you buy or restore. On iPhone the app makes no network calls of its own; it talks to the App Store through the system when you buy or restore.

Where the data lives

• In a database on your phone, encrypted. Quietlift holds no copy anywhere else; there is nothing to delete on our side because there is nothing on our side.
• No analytics, no trackers, no crash reporting that leaves the phone. The privacy page says so in full.
• You can take it out at any time, free: CSV, JSON or Markdown, from More › Your data.

No account, so how is it backed up?

Set a backup passphrase once. From then on Quietlift writes an encrypted backup after every workout: to iCloud Drive on iPhone, or to a folder you pick on Android, on the phone or in a cloud-drive app you already use. The last 30 backups are kept, free. The backup format is published, with a short script that opens it, so the file is useful even without the app.

The passphrase never leaves your phone and cannot be reset by anyone, including us. Write it down somewhere that isn’t the phone.

Moving to a new phone, iPhone or Android

1. On the old phone: More › Your data › Back up now.
2. Put the .qlbak file where the new phone can reach it.
3. On the new phone: More › Your data › Restore from a backup, pick the file, type the passphrase.

A backup made on one platform restores on the other. There is no live sync between devices yet; one file moves everything, and live sync is planned as a later add-on.

Questions

Do I need to create an account?

No. There is no sign-up, no email, no password for the app itself. The only password-like thing is the backup passphrase, which you choose and which stays on your phone.

Does it work in a basement gym with no signal?

Yes. Nothing in the log, the timers or the progress screens needs a connection.

What happens to my data if Quietlift disappears?

Nothing. The app keeps working on your phone, the export is plain CSV or JSON, and the backup format is documented with a script that reads it.

Can I bring my history from another app?

Not in version 1.0. The importer for Hevy and Strong exports is built and held back until it has been checked against real exports. A Quietlift backup moves everything between your own phones.
