The four protocols
All four protocols supported and switchable any time. Start with 16:8; graduate as the rhythm clicks.
16:8
16 hours fasting · 8 hours eating
The most popular protocol. Skip breakfast, eat lunch through dinner. Good entry point for new fasters.
18:6
18 hours fasting · 6 hours eating
A tighter eating window. Common step up from 16:8 once the rhythm clicks.
20:4
20 hours fasting · 4 hours eating
Sometimes called the Warrior diet. One big meal + one small snack inside a 4-hour window.
OMAD
23 hours fasting · 1 hour eating
One Meal A Day. The most demanding protocol — best after running 16:8 and 18:6 for a while.
The timer itself
Phone reboots, app force-closes, screen turns off — your fast keeps running. When you reopen, the countdown is exactly where it should be.
Push notification fires the moment your fasting window closes. No more checking the clock every 20 minutes.
Complete consecutive fasts and watch your 🔥 streak counter climb. Last 30 days of fasting history saved so you can see patterns.
Forgot to start the timer? Tap any day in the History calendar to log a past fast retroactively. Protocol and duration both editable.
Talks to your calorie tracker
Standalone fasting apps don't know you're tracking calories. Standalone calorie apps don't know you're fasting. BiteCaddy runs both in the same Progress tab, so the metrics stay coherent.
Read: the intermittent fasting science guide →Your daily calorie goal is suppressed during the fasting window — no false alarms about being “under” your target when you intentionally aren't eating.
The calorie ring re-engages the moment your fast ends. Log your first meal and the daily totals start counting fresh.
Fasting timer, calorie ring, macros, exercise — all on the same Progress screen. No tab-switching between apps to see the full picture.

FAQ
16:8 is the standard entry point. If you usually eat from 7am to 9pm (14-hour window), 16:8 just means pushing breakfast back to 11am — manageable for most people. Run it consistently for 2-3 weeks before considering 18:6 or tighter.
Yes. The start time is persisted on your device, so closing the app, phone reboots, and screen-off states don't pause it. When you reopen the app, we compute elapsed time from the saved start and display the right state.
Tap End Fast and we log the actual duration. You can also log a meal mid-fast and the timer ends automatically with the actual eating window.
No — that's the point. BiteCaddy has the timer, streaks, history, and notifications built in alongside your nutrition tracking. No subscription to two apps. No data scattered across surfaces.
For most healthy adults, yes — but BiteCaddy isn't medical advice. If you're pregnant, have a history of eating disorders, take medications that require food, or have other medical concerns, talk to a doctor before starting any fasting protocol.
