21. Pennies
Budgeting and financing your life is pretty boring but, crucially, actually quite important. Pennies is a personal finance manager which claims to be as easy-to-use as a children's toy and takes out all the boring bits so you don't have to worry. The app allows you to keep better track of your money which also works with Apple Watch. The app works well on playing on the mind as it isnt concerned with the ins and outs of what youre buying or where that money comes from in the first place. Instead, it streamlines the process so users wont become burdened by all the unnecessary details typically required with financial management software. To get the app to work, all you need to do is choose from one-off or repeating monthly, weekly, or bi-weekly choices, assign a name, start date, and currency type, then enter the amount available to spend. From there, its a simple matter of making entries with each purchase, and Pennies takes care of the rest.
