Log your fasting window against energy, hunger, and mood ratings to see which window length actually works best for you.
Logging energy and hunger against your actual fasting window shows you which window really works for your body, not just what a timer app assumes.

Most fasting apps focus entirely on the timer: when your window opens and closes. They don't help you see how that window actually affects your energy, hunger, or mood over time. This log pairs your daily fasting window with consistent ratings so patterns become visible instead of anecdotal.
Log your actual fasting window each day, along with start and end time, then rate your energy, hunger, and mood at a consistent check-in time so ratings are comparable day to day. After 2-3 weeks, scan for patterns to see which window length or timing gave you the best scores, and adjust based on what your own data shows instead of a generic assumption that one window works for everyone.
We built this because 16:8 works great for some people and terribly for others, and the only way to know which camp you're in is to actually track it. A timer alone can't tell you that; the ratings next to the window can.

Energy, hunger, and mood ratings next to your actual window reveal what works for you specifically.
Rating at the same time each day means day-to-day comparisons are meaningful, not noisy.
A field to note early breaks or extended fasts, and why, so you can see what's actually driving them.
Is this a medical or nutrition tool?
No, it's a personal tracking log only, not medical or nutrition advice; talk to a qualified professional before starting or changing a fasting protocol.
How long before I see a real pattern?
Most people see a usable pattern after 2-3 weeks of consistent daily logging and same-time ratings.
Can I track more than one fasting window length?
Yes, log whatever window you actually fasted each day; comparing different lengths over time is exactly what the pattern view is for.
