## What is Sleepcraft?

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.

### 5/5 — Интересное

*2026-08-06*

Интересное приложение! Это не будильник! Это приложение об вашем сне. Показывает где промахи. Оно как дополнение к трекерам и часам. Познавательно.

**Developer response:** Наталья, спасибо за отзыв 💙

### 5/5 — Second review: still just as impressed

*2026-07-29, version 1.5*

One day I'll learn how to edit a review I've already written...

The love affair with this app continues. Dev just added Shortcuts support. Might only appeal to a niche crowd, but if you're in the market for a bridge between your sleep tracking and your PKM or journal app, this could be a boon for you. Certainly is for me. Set this up to run automatically on a given trigger (e.g. when waking up) and push to your desired endpoint. Simples. Continues to be a fantastic utility for sleep stats.

### 5/5 — 非常好

### 5/5 — Replaced My Go-To

*2026-07-11, version 1.3.2*

Sleepcraft provides the equivalent info, and more useful info, than the app I’d been using for a while. I pop it open every morning to see if I’m improving at all, and I am. Having measurable data is useful.

### 5/5 — First app I check each morning

*2026-07-02, version 1.2*

Have been using since April. Big fan, particularly like the ease of adding in factors and having it track the effect on sleep. The simplicity of it is a huge differentiator to other sleep apps.

### 5/5 — 软件不错

### 5/5 — Replaced My Go-To

*2026-05-26, version 1.1.9*

Sleepcraft provides the equivalent info, and more useful info, than the app I’d been using for a while. I pop it open every morning to see if I’m improving at all, and I am. Having measurable data is useful.

### 5/5 — Good, but…

*2026-05-05*

It keeps double-counting both my sleep hours and steps. Huge thanks for keeping it free!!

**Developer response:** Hi DrBeePhD, thanks for reporting this.

Could you please send screenshots and details to support@sleepcraft.app? That would help me investigate the double-counting issue and fix it. Thanks!
