Sleepcraft vs SwimPaceTimer

Sleepcraft reads your sleep data from Apple Health and breaks it down differently than most apps. It shows your sleep on a 12-hour clock face so you can see exactly when you got deep sleep, REM, light sleep, and awake periods. Instead of one combined sleep score, Sleepcraft gives each phase its own score — deep, REM, light, continuity, and regularity — so you know exactly what's working and what isn't. Scoring is calibrated to your age and sex. A 50-year-old man and a 25-year-old woman have different optimal deep sleep and WASO targets, based on clinical benchmarks from the NIH, CDC, and NHS. You can tag daily factors like late coffee, alcohol, or a hard workout and see how they affect not just your overall sleep, but each individual stage. Some patterns aren't obvious — for some people, ovulation can increase deep sleep, or a daytime nap might actually extend total sleep duration rather than shorten it. Sleepcraft surfaces these personal links so you're not guessing. It also connects your daytime active energy and HRV to nightly recovery, and uses your historical data to forecast tonight's sleep quality based on your current trends. All processing happens on your iPhone. No backend servers, no accounts. Your tagged factors and ratings sync through your own iCloud. Terms of Use (EULA): https://sleepcraft.app/privacy

SwimPaceTimer is an Apple Watch interval timer for the pool. Three settings, that's it: distance, reps, and your send-off cycle. MADE FOR SWIMMERS WHO - are tired of watching the pace clock and counting in their head - just want to hold a send-off without fiddling with settings mid-set WHAT IT DOES - Build a set: distance x reps x send-off cycle (e.g. 25yd x 5 @ 1:30) - Tap start, get 5 seconds on the wall, then push off on the buzz - A heads-up buzz 5 seconds out, then a start buzz - hold your cycle without looking at your wrist - Countdown ring, rep dots, heart rate, split and total time at a glance - Live heart rate on screen while you swim WORKS ALONGSIDE THE WORKOUT APP SwimPaceTimer is a send-off timer, not a tracker. It never takes over a workout you are already recording. Start a pool swim in the built-in Workout app if you want it saved to Health — that also turns on Water Lock for you — then let SwimPaceTimer handle the send-offs. BUILT FOR THE WATER Screens are hard to read and harder to tap when you're wet. Set everything on the wall before you push off, then swim - your wrist tells you when to go. Yards or meters follows your region automatically.
