I recently bought your app.. I like the simplicity and ease of use.. It works as advertised but to be useful to me I have 4 suggestions / requirements 1. It need to correctly manage gas logs for gallons or litres 2. The settings for metric or imperial need to be vehicle specific 3 a method is needed to correct an incorrect gas log entry 4 id like a way to track service time ( hours and fuel use) on things like lawn mowers, snow blowers, boat motors Why... I have 2 Cars using imperial measurements ( gallons, miles ) and one using metric. This is a problem.. When traveling in US, the gas is in US Gallons and priced / gallon When traveling in Canada the gas is in Liters and priced per liter.. So the metrics and graphs of gas mileage get all mixed up and are basically useless. Suggest.. Settings for odometer should be by vehicle ( km or miles or hours of use) not universal for all vehicles. When adding a gas log entry.. There needs to be a way to mark gallons or liters Your program needs to do the correct conversions to present the Miles or kilometers or hours per gallon or liter .. correctly
