Everything you want to track, in one simple app. Made in Japan. This app is made by Yomoe Studio, a small studio in Japan that does nothing but build apps. No flashy effects, no nudges to spend. Our time goes into the details instead — how fast a day is to log, how clearly the charts read, how it feels to come back tomorrow — to make something you can keep up every day without it becoming a chore. Weight Loss Diet Diary: Yomoe keeps your weight, meals, exercise, water, body measurements, bowel movements and menstrual cycle in one place. No account, no sign-up — open it and start logging. ā–  What you can log • Weight — see your trend at a glance on a line chart • Meals — breakfast, lunch, dinner and snacks, with up to 3 photos per meal • Exercise — pick a type and duration; calories burned are estimated from your weight (and you can edit the number) • Water — one tap per glass • Body measurements — waist, hips and more • Bowel movements — a quick daily check • Menstrual cycle — calendar view with estimated next period and ovulation day (shown for female users) ā–  Little things that keep you going • Daily streak counter • 20 badges to collect across 5 categories: streaks, weight, water, exercise and bonus • A gentle nudge when your weight stops moving ā–  Look back with charts Weekly and monthly summaries of weight change, total exercise time and calories burned, water intake and goal days. BMI, body fat percentage and basal metabolic rate estimates are shown too. ā–  Plan your goal Pick your weekly pace with a slider and see the estimated date you would reach your target weight — you decide what pace works for you. ā–  Your data stays on your device Everything you log is stored locally and never sent to our servers, and no account is required. Backup export and import are built in, so your records come with you when you change phones. ā–  Made to be comfortable • 2 theme colors in the free version, all 8 with Pro • 10 languages: English, Japanese, Chinese (Simplified and Traditional), Korean, Spanish, French, German, Italian and Portuguese ā–  About Pro (one-time purchase) The free version gives you every core feature — logging, charts and backup. A single purchase upgrades you to Pro, which adds: • No ads anywhere in the app • Full history in the statistics charts (the free version shows the last 3 months) • All 8 theme colors unlocked (the free version has 2) Note: This app is a logging and charting tool, not a medical device. BMI, body fat, basal metabolic rate, goal date projections, and period and ovulation estimates are reference values based on general formulas and what you enter — they are not medical diagnosis, advice or guidance. Period and ovulation estimates must not be used for contraception or for planning a pregnancy. If you have a medical condition, are pregnant or breastfeeding, or have any concerns about your health, please consult a doctor or other professional before using this app.

Verdict

The call

The clearest difference is ads: Getsuka at none against Weight Loss Diet Diary's shown. Getsuka also leads on update cadence (fortnightly vs every 2 months). Weight Loss Diet Diary's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
