Interface is simple and I like the report export feature. However, the time limit around when you can input +1 and +2 hour readings is too narrow—if you forget to input a reading, it’s very difficult to get the app to accept it and still have it tied to the relevant meal. In settings, you can change the accepted time ranges for inputs, so I made them very broad and now I can’t input any +1 or +2 hour data; it tells me everything is out of range, even though it’s inside the range I set. Not sure how to fix other than delete and reinstall the app, which of course means data loss. If that were fixed, it would be 5 stars.
