## What is Danjiki AI Fasting Timer 16?

No subscription. A one-time purchase, and it is yours.

A simple timer that measures and records the hours you are fasting. It promises no outcome and states nothing about what is happening in your body. It is a tool that shows your own record back to you, honestly.

- One tap from a preset
- 12:12 (for a first try), 14:10, 16:8, 18:6, 20:4 and OMAD (23:1)
- The last preset is remembered, so the next start is a single tap
- A custom length is there if you want to set your own

- Recording, without deciding anything
- Two buttons: start the fast, end the fast
- Ending short of the target says only "recorded, X hours Y minutes", with no word of judgement
- Within a minute of starting, the record can be cancelled without being kept

- Days running, and the week
- Days running appear only as lit days on a calendar. No number is played up, and stopping early is never called a failure
- The weekly total and the usual hours are visible at a glance

- Patterns in your own record
- Once seven completed records are in, something like "in your recent records, more of them started around 20:00" is shown, drawn from your own log
- This is statistics about past records. It is not health advice and not a diagnosis. Nothing says a particular hour is best

- Quiet at night
- Notifications are silent overnight (22:00 to 06:00 by default). Anything that fell in those hours arrives as one factual note when the quiet hours end

- Before you start
- If you have a medical condition, are pregnant or breastfeeding, are still growing, or have a history of an eating disorder, please talk to a doctor before starting
- This app measures and records time. This app is not a medical device and does not replace a doctor or medical care

- Made to be safe to use
- Everything stays inside this device only (nothing is sent anywhere at all)
- No account is needed
- No ads

Your hours, counted honestly.
