HeyFiniThe baby app that learns your rhythm
Feeding, diapers, sleep – HeyFini works out from your last few days when it's probably time again. So you know whether that walk still fits in before the next feed.
How does HeyFini know when the next feed is due?
HeyFini looks at the actual intervals of the last few days and builds a robust average from them – recent entries count more, and a single outlier (that one long morning nap) doesn't skew anything. On top of that the app learns your daily pattern: intervals are often shorter in the afternoon and longer at night. The result sits right on the card as “approx. 15:10”.
The entire calculation happens on your iPhone. There is no server analysing your data.
What exactly does HeyFini predict?
The next feed (breast or bottle), the next diaper change and the next sleep – each with a time. In the Schedule (24-hour view) you also see the rest of the day in advance: predicted naps as blocks with an estimated duration, and upcoming feeds as dots on the timeline. Individual times turn into a day you can plan.
How accurate are the predictions?
Honest answer: it's an estimate – and it gets better with every day you track. After two or three days it matches most babies' rhythm surprisingly well; on cluster-feeding days or during growth spurts it shifts along as soon as new entries come in. The prediction doesn't replace your gut feeling – it gives it a time frame.
Frequently asked questions
How quickly does HeyFini learn our rhythm?
HeyFini shows a first estimate after the very first entries; after two to three days of regular tracking it becomes stable. The more regular the rhythm, the more accurate the times.
Do I need an internet connection for predictions?
No. The calculation runs entirely on your iPhone. The app only needs internet for iCloud sync between your devices.
Will I get a reminder when it's time?
Yes – if you want, HeyFini sends a notification for the probable next feed or diaper change. You can switch it off in Settings.
