Sleep Memo is an app that keeps your log entirely on your device for keeping a simple record of your nightly sleep. Just tap in the time you went to bed and the time you woke up, and your sleep duration is calculated automatically. Add a quality rating (1-5) and a short note to look back on your own rhythm.
■ Quick to log
Pick your bedtime and wake time. Late nights and early mornings that cross midnight are handled correctly. Quality is a simple 1-5, and the note is optional.
■ Last night at a glance
The home screen shows last night's sleep duration and quality, plus your average for this week.
■ Charts of your rhythm
See weekly sleep hours as a bar chart and a breakdown of your quality ratings, so you can spot your own trends over time.
■ Timeline to look back
Browse every record in order. Edit or delete anytime.
■ Home screen widget
Check last night's sleep right from your home screen.
■ On-device and offline
Everything is stored on your device. No account and no connection required. Export to CSV to keep your own data in hand.
Note: This app is a tool for recording sleep. It is not intended for medical diagnosis or treatment. If you have concerns about your health, please consult a professional.
