I am working on redesigning the UX for a carbon footprint tracking app. The issue is when it comes to letting users select miles travelled via airplane, car, bicycle etc..with airplanes, the data range can go upto 200K miles a year or even more. The current design has slider to select number which can be really frustrating to users even to get to the nearest range.
I am trying to figure out a way to solve this problem. Now, the exact amount of miles does not need to be known. One option is to use radio buttons and give them a range. Another option is to have something similar to what we learnt during our school days which involved thousands, hundreds, tens places to understand numbers. Is there some live application where one has to enter data in the range of 100K+ which uses innovative UX? Tried looking at radio applications but that doesn't serve the purpose.
