This app will become a very handy tool to calculate the daily FDI. It seems the app is still being tweaked for a more accurate reading and better user experience. Few suggestions...amount for days since last rainfall needs to go beyond 30 days (seems default is 30 days and goes back to 30 if you enter a higher amount). Maybe add a location function to make the FDI reading more accurate. Over all very well-designed and plenty of information in it. Well done.

Have left a review before, but had to delete for a new review. Have now joined the subscription service. Must say prediction pretty accurate. Only thing is I must search location every time for an accurate reading as it only shows Limpopo when using Gps. Maybe add a pinned location or favorite. Also, perhaps add wind direction for example W or NW which will help. So far great app keep it up

The location and search functionality is still problematic. Won't enable the location. I search for Fish Hoek, and it takes me to Servlet. I have tried several times to use this. It's not working despite my monthly subscription. It's now end January 2026 and no sign of the problem being fixed.
