About the Tally Counter
This is a simple multi-counter for anything you need to tally: gym reps, laps, scores, inventory, habits, or headcounts. Each counter has its own name and value, and every change is saved instantly to your browser's local storage, so your counts are still there after a reload or restart — no account needed. Nothing is sent to a server; the data lives only on your device. The buttons are sized for thumbs, so it works just as well on a phone at the gym as on a desktop. Use Export to download your counters as a JSON file for backup, and Import to load them into another browser or device — you choose whether to replace or merge.
