Log food, drink, sleep, workouts and fasting in seconds, and see how they connect. Insights are worked out on your iPhone, and everything you log goes to Apple Health.
slotho is a food, drink, sleep, workout and fasting diary that also tells you how those things connect. The insights are worked out on your device, and everything you log goes to Apple Health, where it stays yours.
LOG IT IN SECONDS
- Search a food, scan a barcode, photograph a plate, or type "two eggs and a coffee"
- Hundreds of common foods built in, most with their own illustration, plus Open Food Facts and USDA FoodData Central
- Drinks log what is actually in them: water, caffeine and alcohol
- Meals, favourites and plans you can reuse
- Log from Apple Watch, the Home Screen, Siri or a Shortcut
- Delete any entry where you see it, with Undo
HOW FOOD MAKES YOU FEEL
- Six digestion symptoms with severity, where a symptom-free visit counts as evidence too
- Ten more symptoms, from headaches to appetite changes
- Mood check-ins through Apple Health's State of Mind
- GLP-1 Mode: your dose days from Health, with symptoms on the days after a dose compared with later days
- slotho looks for foods that show up before a symptom, using only your own logs, and says so only once the evidence is there
- Correlations across sleep, digestion, energy, caffeine, alcohol and heart-rate variability
- Ask your history in your own words, such as "When did I last eat salmon?", and get the answer from your own logs
YOUR DAY IN ONE VIEW
- A daily balance from sleep, food, activity and recovery
- Energy in against energy spent, plus macros, fibre, sugar and electrolytes
- Water, caffeine and alcohol
- Home Screen and Lock Screen widgets, and an Apple Watch complication
- A report for your dietitian or your trainer, ready to send
FASTING
- An eating window for each day of the week
- Your fast starts when you actually finished eating, not when the schedule said you would
- The stage you are in on Today and on your wrist, stage notifications, and a morning recap for the ones you slept through
SLEEP, RECOVERY AND MIND
- Stages, duration, and how regular your nights are
- Resting heart rate and heart-rate variability against your own baseline, never a population figure
- Training load: this week against your last four
- Breathe, and six guided meditations read aloud
WORKOUTS
- Build plans on iPhone, run them from your wrist
- Timed sets, rests, and exercise notes read aloud on the watch
- Sloth Pacing ends a rest when your heart rate has come back, not when a timer says so
- Save workouts, nights of sleep, meals and mindful sessions to Calendar - slotho only ever adds events, and never reads your calendar
PRIVATE BY DEFAULT
- Correlations are worked out on your device
- Photos sent for analysis are stripped of location, capture time and camera details first
- No account, no advertising, no tracking
