In general this app is exactly what we were looking for. With our first child we jotted down everything in a digital journal, but didn't get a quick an easy overview of total ml of milk or how long ago his last bottle was. This app solves that and then some.
However, there are two things not working that well. First of all is syncing across platforms. It was a pain to find out that Dropbox sync only worked between iOS devices, I had to disable it and set up the apps own syncing option in order to get it working between an iPad, iPhone and Galaxy phone.
Second issue is the widget in iOS doesn't update itself, you have to open the app. This is counter intuitive as that's the only use of the widget. Nonetheless worth the €5.
Now iOS 10 is out, I hope the app gets updated soon to make use of the better widget experience.
