Midnight Mode Turns your screen true black with red-shifted light so you can log a dream feed without blinding yourself. All icons and colors shift, tap targets grow, it can be scheduled, or automatically turn on when low light is detected.

Sleep and wake predictions run on your device, based on your baby's actual data. Rhythm finds the patterns in similar days and shows you the result. If it looks wrong, you can adjust it. It's your data. The whole app works offline by default. Traveling? Basement? Patchy hospital wifi? Doesn't matter. Everything syncs when you're back online.

Make it your own.

Eleven themes: four primary, seven for the adventurous, or build your own. Each has a light and dark variant. Swipe through the primary four:

Boreal theme Dusk theme Hearth theme Willow theme

You can rearrange the dashboard. Create custom event types with selectable fields (medication name and dosage, or tummy time with surface type), then build status tiles that combine them however you want. Add your most frequent events to the thumb dial so you can log them in one swipe.

The full app is free on one device. No ads, no trial that expires. For $5/mo you get sync across devices, partner invites via QR code, and backup. That's it.

Rhythm is a web app, not a native app. No widgets or Apple Watch support yet. But it works in any modern browser and updates without an app store.
