Yes. The app's core functionality is free with no expiry date, no trial period, and no account required. The app is fully functional and you can use it forever without every paying anything.
Nope. There never will be a subscription. There is a one-time in-app purchase for extras and that's it. This is a commitment, not a marketing line.
No. Ads are incompatible with our core principles and values. The business model is one-time purchases. That's it. Check out our manifesto to learn more about what we stand for.
Currently we only target iOS and Android phones and tablets. There is no planned web app but we are open to considering a native Watch App in the future..
Nothing. No analytics, no crash reporting, no advertising identifiers, no third-party tracking SDKs. We have no idea how many people use the app or how they use it. This is a deliberate choice, not an oversight.

No. No sign-up, no email, no login. You open the app and it works. If you make a purchase it is tied to the iOS or Android app store account you used.
On your device. Nowhere else. We don't have servers storing your fasting history because we don't need them — the app works entirely offline. You can import and export your data at any time.
It's gone with the app. Export your data first if you want to keep it or move it to another device. You can find this in the app Settings page.
You set your own target duration. 16:8, 12:12 or anything in between up to 24 hours, anything — you decide. The app is a timer, not a protocol enforcer.
No worries! You can edit the fast start time before, during or even after each fast.
No cloud sync. Your data stays on your device. To move to a new phone, use the export and import tools in Settings. You're in control of your data.
Every calendar day you complete a fast counts toward your streak. Miss a day and it resets. No partial credit and an optional, configurable grace period.
No.It can't! The labels displayed are estimates based on general scientific literature. We have no access to any of your health data.

Yes, via email. We can't promise we'll build everything, but we read everything. If a lot of people ask for the same thing and it fits the philosophy, it gets considered.
Email us. We'll reply, seriously!
