naido as an alternative to Napper
As of: 12.10.2026
You use Napper and are thinking about switching to naido? This page puts both apps side by side: what they share, where they differ according to public information, and how your existing entries come along. Every statement about Napper names its source and date. naido is an independent product by Velmun and has no connection to Napper.
What both apps share
According to the provider’s public information (as of 03.09.2026), Napper also forecasts the next sleep, shows no ads in the app and lets the whole family join with one subscription. The same is true for naido.

Where naido does the maths
With naido your phone computes the forecast itself, even without a connection. Your entries stay on the device, and there is no account. When your devices sync over the internet, our server only holds an end-to-end encrypted package that we cannot read. How the forecast comes about is explained in How naido forecasts sleep.
Bringing your entries along
naido recognises Napper files automatically during import, including the CSV files from the freely available napper-export tool. If Napper is installed on your phone, naido shows you the steps during import. If you like, the app prepares a request for access and data portability under Art. 15 and 20 GDPR, which you send yourself.
If the import brings enough usable history (at least ten sleeps it can recalculate), naido then works out how well the forecast would have hit in it. You see that number before you pay anything. The import runs entirely on your phone.
What naido does not have
naido is an app for forecasting and logging, with a diary down to the check-ups. There are no courses or chat assistant in naido. The app is available for Android; on iPhone the encrypted web app works today, an App Store version is in the works.
What naido costs
The app is free, with no time limit and no ads. Only Naido Premium for the family (sync between your devices, web app, sharing with caregivers) costs €19.99 a year or €2.99 a month (founding price), once for the whole family. If you cancel, your entries stay on your phone.
