Sleep Little Finch

Help your little one — and yourself — get the rest you need.

A calm, privacy-first companion for families using any sleep training approach. Track wake windows, log naps, and get gentle reminders without handing over a single byte of family data to anyone.

Track sleep without spreadsheets

Quick start/stop logging, a clear timeline, and gentle weekly summaries — no fiddly forms.

Any approach, no judgement

Works alongside the sleep training method you already use, from extinction to chair to no-cry.

Local-only by default

Your data stays on your device. No accounts, no cloud sync, no third-party analytics.

Reliable reminders

Schedule wake windows and feeds with notifications that survive a phone restart.
