It would be great if you could add an additional box in the "Vehicle information" section where users can add specs about various parts that require changing them more often or other useful information regarding maintenance. As I mentioned in the header, a good example would be bulb type, wiper size, coolant type, oil type, tire pressure, etc.
But, instead of you manually setting all those fields in the app, set it as an optional field with a possibility to add more lines in it. I have attached an image below which is about how this would look and how it would work - tapping the red "+" button adds two empty fields next to each other with limited number of characters that can be typed (to keep each information in a single line).
I believe it would be a great addition for users like me who use Fuelio for all costs related to our cars, not only fuel. Keep up the good work, I've been using your app for almost a year - it is definitely by far the best one available for the job.
Hope you take this into consideration for a future update, cheers!
