Fat loss tracker

A fat loss tracker shaped like a year, not a stopwatch.

16:8, 18:6, OMAD or light fasting — Streakly logs whether you stuck to your fat-loss plan each day and renders the year as one heatmap. Less daily anxiety, more long-term proof.

Stop counting hours. Start counting days.

Most diet apps obsess over live countdowns and daily scale swings — calories left, hours to go. Useful for a single day, useless for a year. Streakly inverts it: each day is one square, lit if you hit your plan and dark if you didn't. The same view that shows 'six green weeks then a holiday gap' is what motivates you to fill in the gap next month.

Any fat-loss plan fits

16:8, 18:6, 20:4, OMAD, 5:2, alternate-day — Streakly logs the outcome, not the protocol. Log a 1 if you stuck to it, otherwise leave the day empty.

Pair with a weight or mood log

Pro and Lifetime users get unlimited heatmaps. Track your fat-loss plan and weight (or sleep, or mood) in side-by-side grids and watch correlations build over months.

Click a cell to log

Tap any day in the embedded grid — Notion, your blog, the start page — to mark a successful day. No app to open, no countdown to babysit.

Streaks that survive holidays

Streakly's longest-streak counter remembers your best run forever, even after a planned break. Holidays don't erase your year.

Frequently asked

›Will Streakly remind me to stick to my plan?

No — and that's deliberate. The heatmap is for review and motivation, not nagging. Pair it with a calendar reminder if you need timed prompts.

›Can I track eating-window hours per day?

Yes — set the heatmap to value mode and log hours (e.g. 16, 18, 20). Cell intensity scales with the number, so longer windows visually stand out.

›What about cheat days or planned breaks?

Just leave those days un-logged — they show as gaps. Your longest-streak counter keeps the previous best run visible, and the new streak starts from your next successful day.
