About

slotho is a food, drink, sleep, workout and fasting diary that also tells you how those things connect. The thinking happens 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, and Open Food Facts for the rest - 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, and a symptom-free day counts as evidence too - 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 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 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 - Stage notifications, and a morning recap for the ones you slept through SLEEP AND RECOVERY - 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 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 finished workouts and nights of sleep 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, and logging on Apple Watch. Pro adds your daily balance score, the correlations, weekly recaps, your full history, the gallery view and Sloth Pacing - 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/

September 29, 2026

iPhone - Feature: slotho PRO now includes AI with no key of your own. Photograph a meal and slotho lists what's on it, answer a few questions for a meal or workout plan, and typed foods are read for you. Each has a monthly allowance, shown in Settings. - Feature: Guided meditations. Six practices - body scan, breath focus, loving-kindness, wind-down, stress reset and gratitude - read aloud, with your music or Background Sounds lowered rather than stopped. With PRO they are read in slotho's own voice, and customized voice meditations are written for you from a few choices. - Feature: Paste any text and slotho reads it to you as a meditation. - Feature: Ten more symptoms to log - headache, fatigue, dizziness, acne, aches, a racing heartbeat, night sweats, sleep changes, vomiting and appetite changes - and a "No symptoms today" button, so the good days count too. - Feature: Mood, fullness, drinks and digestion log from the Log tab in one tap, with your usual choices first. - Feature: Today shows the fast you are in - the stage, how long, and what comes next - and a fasting streak card that says exactly what counts. - Feature: What you ate, in one card: your macros against a reference range for how you eat, and how much of your food was lightly processed. - Feature: Two new insights: days you ate out, and time in daylight from your Apple Watch, set against how you slept and felt. - Feature: Fitness age, from your Apple Watch's VO2 max or estimated from how active you are. - Feature: A workout on your Apple Watch now shows on your iPhone's Lock Screen and on Today, with pause and end controls. - Feature: Add a note to a workout, and get a notification when you finish that compares it with your usual. - Feature: Save meals and mindful sessions to Calendar as well as workouts and sleep. - Feature: slotho is now in Thai. Apple Watch - Feature: A new home: today's rings, one-tap logging and your workouts on three pages. - Feature: Log water, a coffee or a bowel movement from Control Center, the Action button or the Smart Stack without opening the app. - Feature: Coach Voice with PRO: sets, rests and countdowns called out in slotho's voice. Your own workout notes can be voiced too. - Feature: Switch to another workout mid-session without ending the first and starting again. - Feature: Indoor and outdoor walks, runs and rides are separate choices, so an indoor session never runs GPS. - Improvement: Larger workout controls that are easier to tell apart, and a clear saving screen when you finish.
