The new slotho: your whole day, in balance
We rebuilt slotho from the ground up. See your whole day in one score, log it in seconds, and watch how energy, sleep and caffeine connect. slotho Pro comes with two weeks free.
Everything in its place
slotho already tracked food, energy, hydration, sleep, workouts and fasting — the hard part was finding it. Now it lives in four clear tabs: Today · Log · Insights · Me. See it, log it, understand it, manage it.

Log in seconds
Search a food database rebuilt on USDA data in 28 languages, scan a barcode, or tap a quick action — food, drinks and workouts are all a tap away, and everything syncs with Apple Health.

Your energy, hour by hour
Intake versus burn across the day, your eating window, and water and caffeine at a glance — so the day makes sense while there is still time to act on it.

Find your daily rhythm
Meal timing and sleep, connected on one line, with digestion tracked alongside and gentle, well-timed suggestions. This is slotho noticing your patterns for you — no diet rules, no shame.

Sleep, caffeine and the whole timeline
Every coffee, water and meal lands automatically on one timeline. See how you really sleep, how sleep and eating windows line up, and when that afternoon coffee is quietly costing you a good night.



Workouts, fasting and more
Sessions, streaks and history, with a fasting timer built in — with educational stage tracking that marks the classic fasting milestones (digestion → blood sugar → glycogen → fat-burning → ketosis → autophagy) and gentle alerts as you reach each one.

On your wrist and Home Screen
Log without reaching for your phone — and see the day at a glance from the Home and Lock Screen widgets and the Apple Watch complication.
