Lemon companies has launched the breastfeeding app in the Android store together with Kind en Gezin & Dreambaby. This app has more than 5000 downloads which is not bad for a Dutch-language niche app. Unfortunately, this app is anything but stable:
1) Creating an account sometimes does not work for days.
2) Signing in often does not work.
3) Days of data can be lost due to faulty synchronization.
4) Functions such as sending data to the midwife does not work.
5) Using the app on multiple devices is a disaster.
6) No bug fixes and new features since 2017 despite reports and suggestions from users.
