Fasting log
Session time and history, in one place.
KIVIFY includes a fasting timer and history for people who have already decided to keep this record. You can check an active session and review previous ones alongside your other activities. The app includes preliminary checks; the timer does not determine whether fasting is appropriate for you.

For Android · In English and Spanish
Review the setup before starting
Before the first fast, the app presents safety questions and notices. Your answers inform the restrictions and options available. Enter that information accurately; the app cannot assess circumstances it does not know about.
This page describes the tool and does not recommend a duration or protocol. KIVIFY is not a medical device. If you are unsure whether you should fast, consult a healthcare professional before using the timer.
- Read the initial checks and the notices shown in the app.
- Review the session setup before starting it.
- End the session when appropriate and check its entry in the history.
Review what you have recorded
The active session shows elapsed time. The history brings together saved episodes so you can review them later. It is an activity log, not a measurement of glucose, ketones or other physiological changes.
If your routine changes, review meals, events and reminders too. Having them in one app helps you see the day, but does not turn a calendar into personalized health advice.
Shared challenges use online services
Personal tracking and the “Fast together” option have different contexts. When you take part in a Community challenge, the information you share uses the service's database and is visible to the relevant members.
You do not need to join a group to review your personal record. AI features also use online services and are subject to their conditions and usage limits.
Frequently asked questions
Does the timer tell me how long I should fast?
No. It displays and records a session according to the available setup. It does not determine a safe duration for each person or replace professional assessment.
Can I review earlier sessions?
Yes. The tool keeps a history of recorded episodes. The figures depend on the sessions you have started and ended.
Does a group challenge stay only on my phone?
No. Community participation involves sharing information through online services. You can use personal tracking without enabling that flow.
