Quill is a baby tracker built for one thing: helping you remember, without asking anything of you. Log sleep, feeds, diapers, growth, and milestones — all in a few taps, day or night. No sign-up. No account. No cloud. Everything stays on your phone. Quill was built privacy-first, from the ground up. There's no server, no analytics, no ads, and nothing about your baby is ever sent anywhere. If you want a backup, you make one yourself — encrypted, in your control. Built for real nights, not perfect ones. Dark mode that's actually easy on tired eyes. Sleep tracking that accounts for night wakes. Wake-window guidance that adjusts as your baby grows. Trends you can check over a week, two weeks, or a month. Features: • Sleep, feeding (bottle, nursing, pumping), diaper, and medication tracking • Growth charts with percentile tracking • Milestone log with photos • Dark mode, System-matched or manual • Encrypted local backups — share with a partner via AirDrop • No account required, ever Quill doesn't want your data. It just wants to help you remember the small things, at 3am and every hour after.

Verdict
The clearest difference is in-app purchases: Self at none against Quill's 1. Self also leads on ratings volume (7 vs 1). Quill's advantage is update cadence (every 4 days vs every 3 weeks). On price, rating, ads and device support there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for Self against 5.0 for Quill. That said, the two scores are not equally well evidenced: Self has 7 ratings behind it against 1, so its average is the more settled of the two.
Self ships an update every 3 weeks, Quill every 4 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
