## What is CycleTemp?

Say goodbye to setting early alarms and fumbling with oral thermometers.

CycleTemp turns your overnight sleeping wrist temperature into a clear basal body temperature (BBT) curve. Open the app to see three things: when your period is likely, whether ovulation shows up on the chart, and whether you’re in a fertile window. Data stays on your iPhone—no account, no ads.

CycleTemp is not a community app and not a medical device. It uses inspectable biphasic rules (6 low / 3 high) so you can check the shift yourself. You can also log fever, alcohol, or late nights that may disturb temperature readings.

You can:
• Log period flow, LH tests, symptoms, and intimacy on a calendar
• See follicular, luteal, menstrual, and fertile-window phases at a glance
• Review sleep temperature and resting heart-rate trends
• Quick-log from your watch; glance via Home Screen widgets and Dynamic Island
• Use phase-based encyclopedia, recipes, and relaxation audio (not a substitute for care)
• Export a cycle summary for your clinician
• Send partner notes that omit temperature and period details
• Lock the app with Face ID; keep backups on your device

If your period is late, you have severe pain, or you have PCOS or other conditions, talk to a clinician. CycleTemp does not diagnose, treat, replace pregnancy tests, or serve as reliable contraception.

Automatic overnight wrist temperature needs a compatible watch (Series 8 or later, including Ultra) with Sleep Focus on. Manual entry works without a watch.

Grant Health access to get started. All processing is on-device.

### 5/5 — 难得看到正经做 6低3高体温规则的中文app

*2026-09-26*

之前研究过 Sensiplan 自然法，但市面上的软件大多是靠固定周期硬猜，国外同类软件又没有汉化或者要高额订阅。这个能直观看到低温基线和高温确认的过程，不用自己每天拿纸质本去描点画坐标轴了。逻辑很严谨，希望开发者继续保持这份专业度！

### 5/5 — 冲着本地数据不上云给的五星

*2026-09-26*

现在好多软件不给手机号和云账号授权就根本不让进，经期这种极其私密的数据被收集真的心里犯膈应。这个居然完全不需要注册登录，也没有乱七八糟的数据上传，所有记录都踏踏实实留在本地手机里。就冲对用户隐私的这份尊重，必须好评。

### 5/5 — 好

*2026-09-26*

预测的很好

### 5/5 — 界面极其干净，没有开屏广告和社区推销太舒服了

*2026-09-16*

之前用过好几款老牌的大姨妈软件，里面全是社区、带货和开屏广告，用起来很繁琐。这款软件完全回归了健康工具的本质：不用注册账号收集个人隐私，数据全在本地。
睡眠时手腕温度自动记录生理周期，预测的经期时间挺准的，桌面小组件和手表端看周期阶段也非常直观。找了很久这种小而美的高质感应用，开发者很用心！
