Blundi starts with typical wake times for your baby’s age, then learns from the naps you log. After about a week the window fits your baby. If you mark a day as sick, teething or travel, the window gets wider and that day isn’t used for learning.

Your logs are written on your phone first. If you have an account or share with your partner, a copy is also kept on our server in the EU. We never sell data. Read more in the privacy policy.

Your account is your email address. You get a six-digit code by email and type it into the app, with no password. We use the address for login codes, for restoring your data on a new phone and for important notices about the service. You only get news if you tick the box for it.

Check that the address is spelled correctly, and look in your spam folder. The email can take a minute. After half a minute you can ask for a new code, and the new one replaces the previous one. A code works for 10 minutes, and after five wrong attempts you need to ask for a new one. If it still doesn’t arrive, write to us.

On Android: open Google Play, tap your profile picture, choose Payments & subscriptions, then Subscriptions. On iPhone: open Settings, tap your name, then Subscriptions. You can also tap “Manage subscription” in Blundi. Pluss lasts until the end of the period you paid for, and you keep everything you’ve logged.

If you have an account, open Blundi on the new phone and sign in with the same email address. You get a code by email, and the new phone joins your household and gets all your logs. If you don’t have an account and still have the old phone, open Settings → Sharing and invite the new phone. If you already share with your partner, your partner can invite the new phone. Otherwise, choose Export as CSV in Settings, then Import from CSV on the new phone.

For now, delete the account (Settings → Account and backup → Delete account) and add the new address. Your logs stay in the household.

Choose Delete account or Delete all data in Settings. Read more on the delete your data and account page.

No. Ask Blundi is an AI assistant for everyday questions about sleep and routines. It does not diagnose. If you are worried, contact your doctor or health visitor. In an emergency, call your local emergency number.
