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.

Verdict
The clearest difference is in-app purchases: Sleep Note at none against Sleep Memo's 1. Sleep Note also leads on iOS requirement (15.1 vs 17.0). Sleep Memo's advantage is update cadence (every 2 days vs every 4 days). On price, ads and device support there is nothing between them.
