Frequently asked questions
Does my baby need vitamin D?
Health authorities recommend giving all infants a daily vitamin D supplement (typically about 400 IU per day) from the first days of life, because breast milk alone usually doesn't provide enough – this helps prevent rickets. A practical tip from the guidelines: set a daily reminder so you don't forget. In HeyFini you add it under Medication with a daily reminder and check off each dose. Discuss the exact dose with your pediatrician.
How do I track medication and get reminded?
Under Medication you add a medicine with name, dose and one or more times – daily or on specific weekdays, with an optional end date for courses. HeyFini reminds you via in-app notification or a recurring calendar event with an alarm, and shows a Today checklist to tick off each dose. Perfect for daily vitamin D drops.
How often should a newborn be breastfed?
In the first weeks, many newborns feed about every 2–3 hours, i.e. roughly 8–12 times in 24 hours – ideally on demand. Every baby is different. HeyFini remembers feeding times and the last side used.
How much sleep does a baby need, and does the app show its duration?
Newborns often sleep 14–17 hours spread over the day. HeyFini tracks naps and night sleep, shows the daily total, and in the timeline previews the next sleep as a block with an estimated duration for today and tomorrow.
How many wet diapers per day are normal?
After the first days, about 5–6 wet diapers a day is a good sign of enough fluids. HeyFini counts pee, poop and combined diapers.
Can my partner track too, and is it on Apple Watch?
Yes. With family sharing you both see and maintain the same data live over iCloud – within seconds, each with their own Apple ID. HeyFini also runs on iPad and Apple Watch, with lock-screen widgets and complications.
Can I use pounds, ounces or Fahrenheit, and other languages?
Yes. HeyFini supports metric and imperial units and is available in English, German, Spanish and Dutch, following your device settings. Checkups adapt to your country too.
What is the AI expert chat?
With HeyFini Pro you can ask baby questions in a chat – ChatGPT, Claude or Gemini – even with a photo. It gives general information and is not a diagnosis.
Is my data private?
Your sensitive baby data stays private in your iCloud – no tracking, no ads. See the privacy policy.
Is HeyFini a medical device?
No. HeyFini provides general information and does not replace medical advice. For health questions, consult your pediatrician or midwife.
