计数器 / 点数器

A simple tap counter for anything you count by hand. Tap to count up or down, and the big number stays front and center so you never lose your place.

People reach for a tally counter constantly: gym reps and sets, guests arriving at a door, laps in a pool, knitting or crochet stitches, stock and inventory items, or a headcount at an event.

You can tap the large buttons, use the keyboard, or go fullscreen for a clean, tap-anywhere counting surface that is easy to use on a phone without hitting the wrong thing.

A step size lets you count by any amount, not just one, which is handy when each tap represents a batch, and the counter can go below zero when you need to subtract past it.

Your current count and step are saved in your browser, so they survive a refresh or closing the tab on the same device, and the counter keeps working offline once the page has loaded. Everything stays on your device; nothing is uploaded.
