Is there a free baby tracker with no subscription?
Yes. In Rhythm, tracking, the Huckleberry import, sleep predictions, insights, JSON backup, and CSV export are all free on one device, with no subscription and no account required to start. The $5/month or $45/year household subscription exists for one thing only: syncing that record to a partner's phone, a grandparent's, or a nanny's.

I charge for sync because the servers that keep a household current and backed up cost money to run. I do not sell your data or show ads. Nothing about the free tier is a trial: there is no feature countdown, no ad-supported version, and no email required unless you create an account for sync.
What you give up by staying free is cloud sync. The record lives in that one browser, so a second device won't see it, and clearing site data or losing the device can remove the local copy. JSON backup and CSV export are free, so you can protect against that yourself by exporting periodically.

How this compares to Huckleberry and Nara's free tiers
Huckleberry's free tier includes logging and caregiver syncing, but its sleep predictions (SweetSpot) sit behind Plus at $11.99/mo. Rhythm puts it the other way around: predictions are free, and syncing is the paid part. The full breakdown is on the Rhythm vs Huckleberry comparison.
Nara Baby is genuinely free across the board, including caregiver sharing, with no ads or in-app purchases. If free caregiver sync is what you're after and computed predictions aren't, Nara is a fair choice; Nara has you set your own wake windows from an age chart rather than computing them from your baby's logged sleep. See the Rhythm vs Nara comparison for the rest of the differences.
Questions
Is baby tracker app free?
For Rhythm specifically: tracking, import, predictions, insights, backup, and export are free on one device, permanently, not as a trial. Sync across more than one device is $5/month or $45/year per household.
Do I need to pay to see sleep predictions?
No. Wake-window and bedtime predictions are part of Rhythm's free tier. That's different from Huckleberry, where predictions require its Plus subscription.
What happens if I never subscribe?
The app keeps working. Your record stays on the device you set it up on, and you can export a JSON backup or CSV anytime. You just won't see that data on a second device or have automatic cloud backup.
Is there a completely free baby tracker with no subscription tier at all?
Nara Baby is fully free, including caregiver sharing, with no paid tier to compare against. Rhythm and Huckleberry both have a free tier plus a paid one; where the split falls is different for each, covered in the Rhythm vs Huckleberry vs Nara comparison.
