Open-Source Local-Only AI Baby Sleep Predictor That Replaces Huckleberry SweetSpot Without Sending Your Baby's Logs To A Subscription Cloud
Huckleberry Plus's SweetSpot AI nap predictor is paywalled at $9.99/mo and is the single most-recommended feature for new parents. The free Huckleberry tier is just manual logging with no prediction. The underlying model is widely understood to be wake-window rules + recent-log heuristics, not a deep neural net. Ship an open-source, local-on-device AI sleep predictor (or a self-hosted API behind a $20 one-time mobile app) that gives free-tier Huckleberry refugees the prediction without a subscription or a baby-data cloud.
The model is the easy part - the hard part is parental UX in the middle of a 3am screaming session. Don't ship anything that makes a tired parent open a settings menu. Default everything, predict immediately on log entry, and put a giant 'Lay down now' / 'Wait 15 min' button on the home screen.

Every prediction-capable competitor is cloud-stored and subscription. The interesting niche is the privacy-respecting parent who already runs a Pi-hole or self-hosts and would happily pay $20 once for an on-device predictor that never sees their baby's sleep schedule. The model itself is small enough (rule-based with light regression) to run on-device on any modern phone.
