Track It - Track Your Spending app for iPhone and iPad
Track It is a super simple, lightweight app that lets you do one thing: keep track of your spending while youre out and about. Bought lunch at work? Got a haircut? Record your spending in Track It. Later, you can view your spending entries for the month, all time, or by a date range of your choice.
For Apple Watch users, the Track It watch app lets you see your spending in the last 7 days and lets you record an expense quickly without having to take your phone out of your pocket.
