*Inspired by the Never Miss Twice philosophy from Atomic Habits. Build consistency without chasing perfection. Most habit apps expect you to be perfect. Miss a day and your streak is gone. Two Hearts is built around a simpler idea: Don't miss twice. You start with two hearts. Miss a day and lose one. Miss again before getting back on track and you break your streak. Life happens. The goal isn't perfection—it's returning. Features The Two Hearts System: A gentler alternative to traditional streaks Designed for real life, not perfect days Focus on consistency over guilt Zoom from Day to Year: Track your progress across weekly, monthly, and yearly views See patterns instead of obsessing over individual days Watch consistency compound over time Home Screen Widgets: Check your status without opening the app See remaining hearts, streaks, and progress at a glance Quick reminders to stay on track 100% Private: No accounts No sign-ups No cloud sync No data collection Everything stays on your device. One Habit. One Focus. No endless habit lists No complicated setup No productivity theater Choose what matters most and show up consistently. Why Two Hearts? Most habit trackers are designed around streaks. Two Hearts is designed around recovery. Because success isn't never missing. It's coming back before a missed day becomes a missed week.

Clack is a split-flap board for your screen. Every letter is a real flap on a drum. Send a message and 132 of them spin, clack and land, with the sound and the feel of the physical boards you see in airports, hotels and homes. Then the board goes back to whatever you have scheduled: the time in words, the weather, tonight's scores, your calendar, a quote, or anything with a URL. MESSAGES Type anything and watch it cascade onto the board. Add colour chips with {red}, {green} or {blue}, or a heart. Pin a message so it stays. Send from the app, from Shortcuts and Siri, or from any other device on your network. CHANNELS Switch on the ones you want and the board cycles through them: • Clock, in words or digits • Weather, sunrise and sunset, air quality and UV, the moon • Football and sports scores with your team's colours, and the next fixture • Formula 1, Transport for London departures • Calendar and Reminders • Mail: unread count and the latest sender • GitHub commits, YouTube subscribers, crypto, stocks, exchange rates, App Store ratings • Hacker News, On This Day, any RSS feed • Custom API: point it at any JSON URL and write a template • Mirror the physical board on your wall Almost everything works without an account or a key. ON THE MAC Set the board as your live desktop wallpaper, behind your icons, on every Space, animating as messages arrive. Or install it as a screen saver. There's a menu bar composer, and a one-tap way to hide every window and just look at the board. FOR DEVELOPERS AND TINKERERS Clack speaks the same local API as the physical boards, so Home Assistant, Zapier, n8n, a cron job or a curl command can post to it unchanged. Send plain text or an exact grid of character codes. There's a built-in guide, and a prompt you can hand to your AI so it knows how to talk to your board. THE DETAILS • Flagship (6 × 22) and Note (3 × 15) layouts • Real flap physics: gravity on the fall, a damped landing, per-column stereo clacks • Realism mode: hinge pins, flap thickness, motion trails, print offset • Any typeface installed on your device, or import your own • Optional symbol flaps: arrows, weather, a few objects • Home Screen and Lock Screen widgets • Wall mode: the board alone on black, screen kept awake. Lean an iPad on a shelf. • Quiet hours, so the board sleeps when you do Made by OCTOBER.
