Some days ask more of you than others. Rainfall notices — and meets you with one quiet, well-chosen practice, before you have to ask. A forecast, not a feed Open the app and Rainfall has already sensed the weather of your day — partly cloudy, building pressure, gentle rain — from signals already on your iPhone. No check-ins to remember. No streak to keep. No library to search. If the read doesn't fit, tap "not quite" and tell it what does. It remembers. One practice, chosen for you Each read offers a single short session from a library of original meditations — guided by one of seven distinct voices, set over original ambient beds. Three minutes when that's what fits. Twenty when the day calls for it. Nothing to scroll through unless you want to. Soundscapes to settle into When words aren't what you need, drift off to an endless soundscape — gentle rain, wind, and more — that plays on as long as you like. Your sky, your settings Choose one of five living-sky app icons — Sky, Dusk, Night, Mist, Dawn — so Rainfall sits on your home screen the way you'd like. The Climate tab keeps a quiet weekly record of your weather. The You tab holds your subscription and notifications. Built around one promise: this stays on your iPhone Rainfall reads your day's signals — heart-rate variability, sleep, calendar density — on-device. The raw signals never leave your phone. The Mind Weather inference happens locally. Your weather history syncs only through your own iCloud, never our servers. Mindful minutes are written to Apple Health, where you already trust them. Rainfall is suggestive — never diagnostic. It is not a medical device, a therapy, or a substitute for either. Rainfall Extended A subscription unlocks the longer sessions — 10 or 20 minutes — and every soundscape. The free tier stays free, always: the daily Read, the three- and five-minute sessions, and a soundscape to drift off to. No time limit, no pressure. Feelings are weather. Weather passes. We'll meet you on the other side. Terms of Use (EULA): https://rainfallmeditation.com/terms Privacy Policy: https://rainfallmeditation.com/privacy Rainfall Extended is an auto-renewing subscription (monthly or yearly). The price is shown in the app before purchase and charged to your Apple Account at confirmation. It renews automatically unless turned off at least 24 hours before the period ends; manage or cancel anytime in your Apple Account settings.

Stressy turns what your Apple Watch already measures into one number: your reserve, from 0 to 100%. Sleep fills it. Stress drains it. Calm slows it down. Glance at your wrist or your iPhone and you know how much you have left today. YOUR MORNING STARTS WITH YOUR NIGHT Deep sleep refills your reserve fastest. Stressy reads how your heart and HRV recovered overnight against your own usual, so a short or restless night starts you lower and a good one starts you high. THROUGH THE DAY Every five minutes, your heart is compared with your own calm. Stress drains the reserve, calm slows the drain, mindful minutes and naps recharge it. Workouts and walks count as effort, never as stress. SEE EXACTLY WHY Today shows your whole day in one curve, your stress every five minutes, every activity with what it cost or gave back, and Behind the number: where yesterday ended, last night's recovery, and where your reserve went since you woke up. LOOK AHEAD • Readiness: whether today suits hard training, from your reserve, recovery, sleep and recent training. Plan a workout and see tomorrow's wake-up with and without it. • Bedtime coach: the latest bedtime that still wakes you at 100, 90 or 80%, on a Liquid Glass dial. YOUR WHOLE DAY • Steps: your steps and distance hour by hour and across the week. • Workouts: the route on a map, time, distance, pace, heart rate and its zones, and what the workout cost your reserve. • Stories: turn your steps, sleep or a workout into a video or image for Instagram and anywhere else, made right on your iPhone. YOUR BODY AGE How old your fitness and habits look, in years: your cardio fitness, resting heart rate, steps and sleep, each against what's typical for your age and sex, combined the way researchers build biological age. Every step of the calculation is shown, with the studies behind it. A wellness estimate, not a medical one. YOUR CARDIO FITNESS Stressy calculates your VO₂max itself, from the steady stretches of your runs, walks, hikes and rides and how hard your heart worked against your own maximum, instead of Apple Watch's estimate, which reads low in independent lab studies. Every step is shown. See where you stand for your age and sex, or take the 12-minute Fitness Test on Apple Watch. YOUR NIGHT, EVERY MORNING Wake up to a short sleep summary: time asleep, deep and REM sleep, and how charged you woke up. On the Sleep page, an AI Summary says what the night meant, written by Apple Intelligence right on your iPhone: offline, never in the cloud. Apple Watch has a sleep page of its own, and Sleep widgets put last night on your Home Screen, Lock Screen and watch face. ON YOUR WRIST AND EVERY SCREEN The living tank on Apple Watch, complications and the Smart Stack, plus widgets for your Home Screen and Lock Screen, including today's stress in detail, as bars or as a flowing line, and your steps or distance. MADE FOR iPHONE DUO Open iPhone Duo and your number and your whole day sit side by side: the living tank on one side, Today on the other. Closed, it works like any iPhone. DESIGNED FOR iOS 26 AND LATER A living liquid tank, glass numbers that hold their own liquid, and Liquid Glass throughout. Light and dark appearance, Dynamic Type, VoiceOver and Reduce Motion. PRIVATE BY DESIGN No account. No servers. No analytics. No ads. Your health data is read on your iPhone and Apple Watch and never leaves them. One price, no subscription. WHAT YOU NEED An iPhone and an Apple Watch. Stressy reads sleep, heart rate, heart rate variability, resting heart rate, workouts and their routes, distance, active energy, running speed, cycling power, weight, steps and mindful minutes from Apple Health, plus your age and sex. Wear your watch to sleep for the best results; your personal baseline settles in within about a week. Stressy is a wellness app, not a medical device. Your reserve is an estimate to help you notice how sleep, stress and rest shape your day.

Verdict
The clearest difference is price: Rainfall at Free against Your Stressy's $4.99. Rainfall also leads on iOS requirement (18.6 vs 26.0). Your Stressy's advantage is in-app purchases (none vs 2) and chart position (#149 vs unranked). On review sentiment, ads and device support there is nothing between them.
