Most fat-loss apps make you log every calorie. Fat Loss Ratio asks one honest question instead: did you stick to your plan today? You pick the plan — a calorie deficit, keto, intermittent fasting, or Mediterranean — and the only number we ask you for is your diet adherence. No food diary, no calorie math to do yourself, no dashboards to decode. ONE HONEST NUMBER The scale lies day to day — water, sleep, salt. Your diet adherence doesn't. Tap once a day: did you stick to your plan, yes or no? That's the whole ritual — and you never log a single calorie. LOG AS LIGHT OR AS DEEP AS YOU WANT • Simple mode — one tap a day: on plan, one slip, or off plan. Done in two seconds. • Detailed mode — a checklist of the meals you plan to eat, pre-filled for your diet style and yours to edit. Tick each off as you eat it; eat something off-plan and it counts against your day. Still no calorie counting. WATCH IT ADD UP • A live adherence percentage with a 7-day ribbon — your week at a glance • A streak that celebrates consistency, never shames a slip • A projection: at this pace, here's the date you reach your goal weight YOUR SUNDAY READING Every Sunday you get one verdict from your week — adherence crossed with your weight trend: • Stay the course — on plan, scale moving • Change the plan — on plan, scale stuck • Stick to the plan — off plan, scale stuck Each comes with one clear next move. No dashboards to interpret. SEE THE TWO LINES THAT MATTER The Trends chart overlays your diet adherence against your weight, with your adherence target marked, so you can see for yourself what consistency does. WEIGHT, YOUR WAY Log on a clean dual-wheel scale, or connect Apple Health and let your trend fill in automatically. You choose the source — we never fake a "Connected" badge we can't honor. NO GUILT, NO NOISE One optional weigh-in reminder a week. No streaks-or-die guilt, no daily pings. Share a clean progress card when you want to — that part's free for everyone. FREE FOREVER, PRO WHEN YOU WANT IT The core app stays free: daily adherence, the 7-day ribbon, one-tap daily logging, your editable meal checklist, your weight tab, iCloud backup, and a week of history.
