*** Track the last time you did something *** Struggling to remember the last time you got sick, had your car washed, or went to grocery store, but then realize you have no way of knowing because you didn't note it down? 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.

Lucent uses neuroscience-backed visual focus training to prepare your brain for deep, distraction-free work in just 60 seconds. HOW IT WORKS Stare at a glowing horizontal line. Watch mesmerizing flares rise and fall. Let your gaze naturally focus. In 60 seconds, your brain's attention circuits activate and you're ready for hours of focused work. THE SCIENCE Based on research from Stanford's Huberman Lab, visual focus on a single point for 30-60 seconds triggers neurochemical changes that enhance concentration, increase goal-directed behavior, and reduce perceived effort during cognitive tasks. Key research: Visual focus increases task performance by 23% and reduces effort by 17% (NYU Study, Psychological Science 2019). WHY IT WORKS Your visual system is the gateway to your attention. By training your eyes to focus on a single point, you activate the neural circuits responsible for sustained concentration. This isn't meditation—it's neurochemical priming. WHAT YOU GET • 60-second visual focus sessions • No ads, no subscriptions • Science-backed methodology
