Features

One giant number. One big tap target. Count reps, cups, laps, tasks, birds, or anything, without hunting for a tiny button. WHY YOU'LL LIKE IT - A number you can actually read. The count fills the screen, so a glance from across the room is enough. - Tap to increment, and that's it. The whole lower half of the screen is your "+". Subtract and reset live right beside it. - Keep every tally in one place. Add as many counters as you like, each with its own name and color, and switch between them with a swipe or a tap on its colored dot. - Undo a reset. Zeroed the wrong counter? One tap puts it back. MAKE EACH COUNTER YOURS - Twelve colors to tell your counters apart at a glance. - Count by any step: by 1, by 5, by 10, whatever you're tracking. - Allow negatives, or clamp at zero. - Sound and haptics on every change: pick a sound and a haptic feel, or keep it silent. Set it once for the whole app, or override it per counter. BUILT FOR ONE HAND - Left- or right-handed layout, app-wide or per counter, so the buttons land under your thumb. SEE IT ADD UP - Every counter keeps a history. Open the graph to watch your count climb over time, with a running event log of every + and - and when it happened. PRIVATE BY DESIGN - Everything lives on your device. No account, no sign-in, no tracking. Whether you're counting reps at the gym, cups of coffee, inventory on a shelf, or bugs in a sprint, CodeYam Counter makes it a single satisfying tap.
