Activity Jot will make keeping track of those activities feel like a breeze. With just one or two taps away, you will quickly save the date, end date, note and amount of any activity. *** Simple and Fast *** Activity Jot presents most important info of your activity front and center. Open the app and you instantly see how many days ago you did an activity together with any end date, note or amount that you kept track of. Want to add new entry for an activity? Tap on the big plus button to create new entry right there on the home screen! *** See all the data at a glance *** Activity history contains all the necessary bits you want to know with a simple yet beautiful heat map view. You are just one tap away from figuring out how many days were there in any streak, what is the longest streak and what is the average streak of an activity you are trying to build a habit for. If you use the amount feature to track, says, grocery spending and running distances, you can quickly see the average cost of grocery this year or the total distance you ran in the last month as those information will be automatically calculated for you. *** Make your life easier with widgets, tags & default values *** Activity Jot works out of the box without you having to configure anything. But when you want to customize the activities and flow, you can tinker with various options and specify default values to make tracking activities even faster. Try adding a widget, or two, or ten! And you can track your favorite activities right there on the iOS home screen without opening the app! Or when you have a lot of activities, sorting into tags will help keep them organized.
