Weight loss, fasting & shot logs in one app, plus a cloud that grows.
Built for foldable phones: log on the left, see your trend on the right when it's unfolded.
Weight loss, fasting and shot logs in one place, plus a cute cloud that grows with you. No ads, no account, and your data stays on your phone. Kumo starts with a 10-second daily weigh-in. Turn on fasting, shots, or water and protein in Settings, and Today shows only what you switched on. It works just as well whether or not you take GLP-1 shots.
10 seconds a day
Opens on today with your last weight ready; tap ±0.1 and you're done
"Didn't weigh today" still counts, so your streak keeps going
Add 1–2 extras: water, mood, protein, waist, shots, or your own
See the trend, not the noise
Daily dots with a 7-day average line, by week, month or 3 months (3 months with Kumo Full)
This week's average vs last week, at a glance
Log non-scale wins: looser jeans, easier stairs
Body stats & goal estimate
Waist, body fat %, hips, chest, thigh, upper arm and neck, each with its own trend
At your current pace, see an estimated date for reaching your goal; until there's enough data, Kumo asks you to log a few more days
It's only an estimate. Go at your own pace
Fasting timer
12:12, 14:10 and 16:8; 18:6, 20:4 or custom with Kumo Full. Start in one tap, and edit the start time if you forgot
A reminder when it's time to eat a proper meal. Kumo never pushes you to fast longer; stop whenever you need to
If you're pregnant or breastfeeding, under 18, or have an eating disorder or a chronic condition, talk to your doctor before fasting
An optional shot card (only if you want it)
Next-shot countdown, a map of recently used sites and how-you-feel check-ins. Records only, no interpretation
Log the date, site and your own notes
Get reminders on the schedule you set
Records only: no calculations, no suggestions
Water & protein
Tap +1 glass of water or +10/20/30 g of protein; rings show today's progress at a glance
A cloud that grows
Grows through 5 stages with the days you show up, not with your weight. Up or down, your cloud is happy to see you
Dress it up and switch themes: sunny, rainbow, rain, snow and starry night (Kumo Full)
Widgets & weekly progress card
Home screen widget: logged today, streak, weekly trend
A progress card every week. Shows the change and the curve, never your weight. Share in one tap
Your data is yours
Stays on your phone. No account, no ads
Optionally import your weight from Health Connect; export to CSV or PDF (Kumo Full)
Free version & Kumo full
The free version works the moment you open it, with no purchase screen: weight with the 7-day average line, the last 30 days of trends and history, 1 body stat, 1 reminder, every widget and your cloud, plus 1 module of your choice (fasting, shots, or water & protein). Kumo Full adds: all modules at once, all body stats, 18:6, 20:4 and custom fasting with fasting charts, the live fasting timer in your notifications, 3-month and all-time trends with your full history, trend overlays, photo before & after, CSV and PDF export, more reminders and water reminders, plus every outfit, color and weather theme. You'll only see Kumo Full when you tap one of its features. Choose monthly or yearly, or if you'd rather not subscribe, buy it once.
