HeyFiniHeyFini understands your rhythm.
The baby tracker that predicts the next feed and nap, tells you what is different today and finds connections. Plus a baby monitor. No account, no tracking.
What is different today
After two weeks HeyFini knows your normal and says it in one sentence: “Slept 10 h 15 min last night, 38 min less than usual.” The “Today vs. Normal” card compares night, sleep, meals and diapers with your own rhythm, only up to the same time of day. No judgement, but the numbers behind it.
From three weeks on HeyFini looks for connections: “On teething days the following night was 40 min shorter on average.” A connection, not a cause.
Finally plan your day
HeyFini learns your rhythm from the real intervals of the last few days – and shows you when the next feed, the next diaper change and the next nap are probably due. In the 24-hour schedule the rest of the day is already laid out, including predicted sleep blocks with their duration.
Everything is calculated on your iPhone – no server ever sees your data.
Ready for the first spoonful
Over 230 foods with safety notes and the right preparation for 6, 9 and 12 months – bell pepper for instance means steamed soft in strips at 6 months and raw from 12. Plus a readiness checklist, a food passport and an allergen companion for all 14 major allergens. The Solids Journey guides you through the first 100 days – its milestones tick themselves off from the meals you actually log.
Every safety statement carries its source: BfR, Gesund ins Leben, AAP, ESPGHAN.
Baby monitor? Already built in.
Your second iPhone becomes the baby unit – with live video, two-way talk and AI cry detection that runs entirely on the iPhone. From the parent device you dim the night light and switch on the flashlight when it's pitch dark, and a third device watches along with one tap, no code needed. At home both devices connect directly over Wi-Fi – no server; on the go it works over LTE/5G. Always end-to-end encrypted.
🧠 AI detects crying – locally
The AI tells right on the iPhone whether your baby is crying or the dog is just barking. Nothing leaves the device.
🎙️ Two-way talk
Hold to talk – your voice soothes from any room.
🌙 Night light & lullabies
Remote-controlled and dimmable: warm light, white noise, heartbeat – or your own voice.
🔋 Battery & connection watchdog
Cable unplugged, battery empty, Wi-Fi gone? Your iPhone raises the alarm immediately.
One tap. Done.
A feed starts with one tap on “Left” or “Right” – HeyFini suggests the side that's due. Diaper changed? One tap. And because nobody wants to open an app at three in the morning: starting the timer and switching sides also works from the Apple Watch, from the widget and straight from the Lock Screen.
Say it instead of typing
Tap the mic and say “wet diaper”, “120 ml bottle” or “asleep”. HeyFini shows what it understood, one tap logs it. Recognition runs on your iPhone, nothing goes online.
Siri understands amounts now too: “Hey Siri, 120 milliliters bottle in HeyFini.” And for nights there is a dark layout with big buttons.

Everything for the paediatrician visit
Weight, height and head circumference with WHO percentiles, well-baby check-ups automatically by age, vaccinations with reminders, medication with a check-off list – and a weekly PDF for your midwife or the practice. All in one place instead of three notes and two apps.
