Built for 3am.
A tracker is only useful if it works in the hallway with one bar of signal, half-asleep, holding a baby. Here's how the Cradlo app is engineered for that moment — plainly, without overclaiming.
The app logs first, syncs second
Every log you make in the Cradlo app for iPhone and Android is written to your device first and queued locally. If you're offline, nothing blocks and nothing is lost — the queue syncs on its own the moment a connection returns.
Nothing duplicates
Each entry carries its own unique ID from the device that created it, so a log that syncs late — or twice — is recognized and recorded exactly once. A flaky connection can delay a log; it can't double it.
One log, every caregiver
Logs sync in realtime to everyone in the family, and running timers are shared too — a sleep timer started on one phone can be stopped from any caregiver's device. Whoever is holding the baby has the whole picture.
Dead spots and airplane mode
Basements, flights, rural weekends — the app keeps logging through all of them and reconciles when you're back. The web app at cradlo.app is the one surface that needs a connection; it works everywhere you have one.
Try it at your 3am.
The apps are free to try for 7 days — log a night with them and see if the quiet reliability earns its place.
