Great for tracking allergies. Great for tracking new allergies. Great for those who have year round allergies. Great for those who want to keep track to show your doctor. This is really a great app all around. I would however like to suggest adding a comment section for the day, and possibly a way to add an entry from the day before in case you forgot. Ive only had this app for about 2 weeks and so far it's really helped clarify what allergies I need to watch for.

unusable now just get a constant aggressive "location accuracy" pop up and can't even go on the app, shame as it used to be really useful. can turn off location permissions to fix this but will not save my location and keeps defaulting to london.

Frustrating that you download the app and it only supports about 8 countries without making that clear beforehand. I'm sure that some of the functionality would be universally useful for hayfever sufferers.
