Everything you need for the newborn months. Nothing you don't.
Nestling — the calm, offline companion for newborn care. No account, no cloud, no ads — every feature works in airplane mode.
Privacy is the feature.
Most baby apps quietly upload the most personal data there is. Nestling is the opposite.
Works offline, always
There is no network code in the app at all. Turn on airplane mode and every feature still works.
Zero data collected
No accounts, no analytics, no servers. Everything you log stays in a private database on your device.
No ads, ever
No ad SDK, no tracking, no interruptions during a 3am feed.
On-device intelligence
Cry detection, label scanning and voice logging run entirely on your phone. The mic and camera never record or upload.
Verify it yourself.
Turn on airplane mode. Every feature in Nestling keeps working — proof that nothing depends on, or is sent to, the network.
One-tap logging. Smart tools, all on-device.
