How am I today? Why? And what should I do? Rest Signals reads what your watch already records in the Health app and gives you one honest answer every morning, judged against your own usual, never against a chart of strangers. Everything is computed on your iPhone. Nothing is uploaded. TODAY A Readiness Score from your sleep, HRV, resting heart rate and activity, each judged against your own usual range and named on the card as good, a bit off or low. Tap it and see every signal, how much it counted, and what was missing. A banner for the day with the one thing to do, and the insights behind it. WHAT WE'RE WATCHING Nothing the app finds waits on a page you'd have to open. Your watch's own health alerts, blood pressure over the NHS lines and low overnight oxygen come to the top of Today with what they can mean and what to do, and stay there until you've booked a GP appointment. Slower patterns over weeks, like breathing at night, resting heart rate, HRV or walking speed drifting, sit underneath with their trace. While an alert is open, the score and training stay easy. A summary for your doctor, ninety days of readings with charts, is one tap away. YOUR DAY, READ BACK IN ORDER The day as one strip from midnight to now, and under it the moments that matter: when you woke and how the night compared, the overnight HRV, each workout, every stretch where heart rate at rest sat calm or ran high with what surrounded it and when it settled, where you are now, and tonight's wind-down time. SLEEP, TAKEN SERIOUSLY Graded against your own need, with "broken" said out loud when a waking runs past half an hour. Your need measured from alarm-free mornings. A regularity score. The night in one line. Room noise under the timeline. A night detective that names the most likely cause of each waking from heart rate, temperature, breathing and noise, with nothing to log. Tonight's plan worked back from your wake-up target. Naps, night shifts and time zones handled properly. STRESS AND RECOVERY, TOLD APART Stress is your heart rate at rest through the day against your usual, with workouts and walking left out. Recovery is the overnight index. Connect your calendar and see which meetings raise it. FITNESS AND WHAT TO TRAIN Pick a goal, or two that go together, and Fitness says what to do each day: the session, the heart-rate range, and why, from your own week and your own nights. Rings, workouts with heart-rate zones, and what each kind of workout costs you the night after, ranked over the season in plain words. A fitness age against your real age, with a 12-week trend and one line per habit naming the study behind it. WIDGETS AND SHARING Home and lock screen widgets you can set up yourself. Share cards for your day or a workout, on a transparent background. INSIGHTS What goes with what, in your own numbers over the last year, shown only when a pattern clears the noise. Trends, highlights and a weekly review. A COACH THAT ONLY SPEAKS WHEN THERE IS A NUMBER BEHIND IT A morning read, a move nudge and tonight's plan. At most three a day, off until you switch them on. HONEST BY DESIGN No data is never zero. Partial scores are labelled. Every finding shows its evidence. Fitness age names its studies. What's new with every update. PRIVATE Reads the Health app with your permission, and writes back only the water and caffeine you log. No account, no sign-in, no analytics, no advertising, and no location.

You no longer log food in Rest Signals itself. • Did you eat enough for the work? A new card on Fitness compares what you ate with what you burned on hard training days, and how you scored the next morning. • UI improvements. • Bug fixes. ### 1.9.2 — 2026-10-07 • Your night, reading by reading: Oxygen and Breathing open on last night, with the night's number, the lowest or highest reading, and every reading on one chart you can slide along. Your own oxygen checks sit beside it. • Tap your day: every moment in Your day so far opens what it came from. Your night opens Sleep, the calm and stressed stretches open Stress, and a run opens that run. • Your race target: on the race page, your target sits beside what your runs predict, with the pace it takes and the 5 km and 10 km times that would put you on course. One tap shows how the prediction is worked out, from your own run. • A fairer call after a short night: one short night no longer overrules a good recovery. Training for a race, Today says when your long run is still to come, and a short night at the end of the week won't stop it. • UI improvements. • Bug fixes. ### 1.9 — 2026-10-06 • A new look: Today, Health, Sleep, Fitness, Vitals, Insights, Heart Rate and Stress are lighter and calmer. Each page says what it found first, then shows your day or night as a chart you can slide along. • Wake-up times: a time for each day of the week, or no alarm on a rest day, and a change for one morning when you need it. • Stress through your day: one line, ten minutes at a time, from your readings while you were still, with your walks, workouts and what you log along the top. • Your night, stage by stage: last night across the hours on the Sleep page. • UI improvements. • Bug fixes. ### 1.8 — 2026-10-05 • Readiness, read back: tap Readiness on Health for every morning's score, the week's average, and the morning it started to drop or rise, with what moved it. • Train for a Hyrox: Hyrox sits beside the running distances under Train for a race. • Your goal, how it's going: one card on Fitness says whether your goal is working, from the evidence that goal is judged by. • UI improvements. • Bug fixes. ### 1.7.1 — 2026-10-04 • Sleep analysis improvement. ## Apps similar to Rest Signals | App | Rating | Price | Category | | --- | --- | --- | --- | | [Unleashed Performance](https://appshunter.io/ios/app/unleashed-performance/id6448870920) | — | Free | Health & Fitness | | [Gastro Meal Prep](https://appshunter.io/ios/app/gastro-meal-prep/id1473099686) | 4.8 (21) | Free | Health & Fitness | | [Glapp — Smart GLP-1 Tracker](https://appshunter.io/ios/app/glapp-smart-glp-1-tracker/id6756984097) | 4.7 (965) | Free | Health & Fitness | | [ROXFIT](https://appshunter.io/ios/app/roxfit/id6476465403) | 4.8 (4,221) | Free | Health & Fitness | | [My Water: Daily Drink Tracker](https://appshunter.io/ios/app/my-water-daily-drink-tracker/id964748094) | 4.6 (24,209) | Free | Health & Fitness | | [David Lloyd Clubs](https://appshunter.io/ios/app/david-lloyd-clubs/id1037992616) | 4.7 (690) | Free | Health & Fitness | ## More apps by Fadi Josef - [MelClimate](https://appshunter.io/ios/app/melclimate/id6809582285) All apps by Fadi Josef: https://appshunter.io/developer/6807522602 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
