Rain and nature sounds to help you fall asleep, relax and focus. Sleep Maker Rain is a quiet, single-purpose sound app. Open it, press play, and one of eight recordings loops seamlessly for as long as you need it — no sign-up, no paywall, no ads, nothing between you and the sound. EIGHT SOUNDS • Rainy Street — steady rain on pavement • Heavy Rain — a full downpour • Rain on a Tin Roof — close, sheltered rain • Thunderstorm — rain with distant thunder • Ocean Waves — surf rolling in and out • Mountain Stream — running water over stones • Waterfall — deep, constant white noise • Birdsong — a calm morning outdoors SLEEP TIMER THAT FADES Choose how long you want to listen, from a few minutes up to two hours. The volume fades down over the last 30 seconds and playback stops on its own, so nothing ever cuts off mid-sleep and wakes you. PLAYS WITH THE SCREEN OFF Playback keeps going when you lock your phone or switch apps. Play, pause and change sounds from the Lock Screen, Control Center or your headphones — the current sound and its artwork show up there too. THREE ARTWORK THEMES Every sound has its own cover art in three different styles: Vivid, Paintings and Classic. Pick the one you like and the whole app follows it. MADE TO STAY OUT OF THE WAY • Works completely offline — every sound is inside the app • No accounts, no subscriptions • Light, dark or system appearance • iPhone and iPad • A separate in-app volume slider, so ambience level and device volume stay independent PRIVATE BY DEFAULT No analytics, no trackers, no data collection of any kind. Your preferences are stored on your device and deleted with the app. Good for falling asleep, napping, calming a restless night, masking traffic and neighbours, reading, studying, working, meditating or simply slowing down.

Snap a photo of any meal — Lean's AI counts the calories and macros in seconds. No searching food databases, no weighing, no barcodes, no typing. Then Lean goes further than any calorie counter: it explains WHY your weight changes — not just that it did. And you can ask it anything. HOW IT WORKS • Point your camera at your plate → AI estimates calories, protein, carbs & fat • One tap logs it to your daily calorie budget • Step on the scale each morning and log your weight in 10 seconds • Lean syncs your steps, sleep and burned calories from Apple Health automatically • Your AI coach connects the dots: "You're up 0.4 kg, but you slept 5 hours and had 3,100 mg extra sodium — that's water, not fat." • Ask your coach a question any day — "why am I stalling?", "what should I eat tonight?" — and get an answer built from your real numbers WHY LEAN WORKS Most apps show you numbers. Lean interprets them. Weight fluctuates daily for reasons that have nothing to do with fat — Lean's coach knows your sleep, steps and meals, so it can tell the difference and keep you steady through plateaus. Setup takes two minutes and asks what actually trips you up — cravings, late-night eating, diets that didn't stick before — so your plan fits your life from day one. STAY ACCOUNTABLE Invite a friend to Lean, cheer each other on, and join community challenges for streaks, steps and consistency. Streak Shield covers a day you miss, so one slip doesn't undo weeks of progress. FREE FOREVER • Daily weight log, trend charts & streaks • Apple Health sync • 3 AI meal scans • One AI coach question every day • A fresh AI insight every week, built from your own data • Today's meals from your personalised plan • CSV export & daily reminder LEAN PRO • Unlimited AI meal scans • A personalised AI insight every morning — not once a week • Unlimited coach chat • A full 7-day meal plan and shopping list, built around your allergies and taste • Plateau detection with AI diagnosis • Pace coaching and a forecast to your goal date • 7-day moving average and body-fat estimate Your health data stays yours. Lean never sells your data and never shows ads. The AI coach runs on-device with Apple Intelligence where available.
