slotho brings food, energy, sleep, movement and more into one clear view — quick to log, easy to read, and genuinely yours. See it, log it, understand it.
iPhone · Apple Watch
Each part of your day gets a clear, honest screen. Log in seconds, then watch the pieces come together.
One balance view ties sleep, food, water, activity and recovery together with a simple daily score — so you always know how today is really going. Around it, what the moment needs: how full that meal left you, and when the evening’s last coffee and last meal should be.
Photograph a plate, search a food or type it in your own words. Water, coffee, mood, fullness and digestion are one tap from the list, with your usual choices first — and Breathe and guided meditations sit in the same place.
slotho looks for what moves together in your own log — a food and the bloating that follows it, caffeine and the night after — and says it plainly, with the count behind it. It waits until there is enough data, and it never diagnoses.
Sleep stages from Apple Health, night after night, drawn beside your eating window — with 7- and 30-day recaps and streaks that count weeks, not days, so one bad day never resets them.
Set your first and last meal for each day of the week. slotho follows the fast you are actually in, from what you logged, and explains each stage as it comes. Educational, not medical advice.
Sessions this month, a monthly score and every workout’s history, with a fitness age from your Apple Watch’s VO₂ max. Build a plan once — or have one drafted from a few choices — and run it on your wrist.
Today’s rings on the first page, one-tap logging on the next, and workouts with heart-rate zones and switching mid-session. On watchOS 26, log water, a coffee or a bowel movement from Control Centre, the Action button or the Smart Stack without opening the app — and follow a watch workout from your iPhone’s Lock Screen.
The everyday tracking is free. slotho PRO unlocks the deeper picture — richer balance, insights and history — and AI that reads your meals and drafts your plans, with no key of your own.
