About slotho
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, favorites and plans you can reuse - Log from Apple Watch, the Home Screen, Siri or a Shortcut 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 - 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, fiber, 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 FREE, AND PRO Free is a complete diary: unlimited food, drink and symptom logging, the fasting timer, unlimited meal and workout plans, breathing and guided meditations, and logging on Apple Watch. PRO adds your daily balance score, the correlations, weekly recaps, your full history, and Sloth Pacing and Coach Voice on the watch. PRO also brings its own AI, with no key of your own: meal photos and typed foods read, meal and workout plans drafted, customized voice meditations and your workout notes voiced, and questions about your history answered, all from one monthly balance of credits. Monthly or yearly, with a free trial. Also on iPad and Mac, kept in step through Apple Health and iCloud. Terms & Conditions: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
What’s new
Version 26.6 · Updated October 11, 2026
iPhone - Feature: Ask Your History. Ask in your own words, such as "When did I last eat salmon?", and slotho answers from your own logs. Free with Apple Intelligence or your own key, over the last 31 days; with PRO, slotho's own AI answers from your full history. - Feature: Reports for your dietitian and your trainer: your food diary, or your workouts set by set, compared with your goals, as a PDF ready to send. - Feature: Snap a Meal takes up to five photos at once from your library. Each is read on its own, so one that fails can be retried without touching the others. - Feature: Ask AI for a meal plan in a cuisine you choose, built around up to five ingredients you pick from slotho's food list. - Feature: Replace Ingredients on a recipe: tick what you don't want, and AI suggests a replacement for each. - Feature: Compare and merge workout plans. Put an imported plan beside yours, or any two of your own, and keep yours, take theirs or keep both, exercise by exercise. - Feature (beta): Exercise demonstrations. An animated figure shows how 30 common exercises are done. For now, slotho shows one by itself only when an exercise's name matches; for the others, choose the demonstration in the plan editor. - Feature: Thai food: pad thai, sticky rice, som tam, green curry, tom yum, moo ping, durian and more, with their nutrition. - Feature: Set a default rest length in Settings, Workouts. - Improvement: slotho PRO's AI now runs on one balance of 1,000 credits a month, spent on whichever features you use most, and a typed food can get its own drawing again. The free trial includes 300 credits. - Improvement: AI meal plans keep each meal to one cuisine and check every ingredient against your diet, and meal suggestions leave out foods that don't fit it. - Improvement: Food search shows slotho's own foods and your favorites within a second, and other sources join below as they answer. - Improvement: Calmer colors, especially in dark mode. Apple Watch - Feature (beta): Tap an exercise's title during a workout to see how it is done, for exercises with a demonstration. - Feature: Hold sets for stretches and static holds. The watch counts up, tells you when the time is reached, and waits for you to move on. - Feature: Voice the Countdown. During a timed set or rest, slotho says the seconds left: every ten, then each second from ten. - Feature: Coach Voice closes each workout with a short line, and can announce every set after a rest, not only the first. - Improvement: The Workouts page has three ways to start: Favorites, Planned and All Workouts. Pinned workouts are now Favorite Workouts.
