iOS/Mac: You have a lot of excellent options for tracking your habits, but Habitify is one of the first we've seen that not only looks good, it also includes a charity donation when you do well. As an app, Habitify hits all the key points for tracking habits. It includes apps for iOS, Mac and Apple Watch; features customisable reminders; includes options to track multiple habits and routines on different days of the week; and even tosses motivational quotes your way if you need them. You're limited to three habits in the free app, but you can unlock an unlimited amount for $5.99. As you check off those habits after completing them, you earn points. Every 500 points you earn, Habitify donates 5¢ to Charity: water, a clean drinking water campaign.
