Calendar function keeps crashing

The app is beautiful and well designed but the calendar reminder function is completely broken, which is what I bought this app for. The app just crashes whenever you try to use it.

Great App.

I love your app, at first I difficulty enabling the GPS but once it got enabled it worked like a breeze.

Response from developer

Hello, when adding/editing just enable "Use current location (GPS)" to get current position when choosing the location. Its working perfectly fine on all my testing devices. See https://reneph.de/en/blue-hour/blue-hour-for-ios/help/#add_location Best wishes

Review

Seems like a neat app but after I purchaser it I was never able to enter my location. It would just return the initial screen. Contacted support and they replied but not able to fix problem. So it was useless.

Great for the price

Compared to a lot of the other apps that do a similar thing this one stacks up quite well. Especially when you look at the prices. It could use a few enhancements but it is great at what it does.

Needs to show direction you're facing

It's good for shooing times and directions. Would be greatly improved by adding a VR aspect. Also if the map would show the direction you're facing that would be great.
