Read full descriptionHide full description
App Overview "x20 Counter" is a simple, streamlined multi-counter app that lets you track up to 20 items at once. No fussy setup required — open the app and start counting right away. Key Features 20 Simultaneous Counters View and track up to 20 items in parallel at once — perfect for keeping tabs on multiple things at the same time. Intuitive Controls Tap to add +1, long-press to subtract −1. Precise, one-handed operation without needing to stare at the screen. Freely Customizable Labels Rename each counter's label to fit your needs — names, item types, categories, and more — to build a list that's entirely your own. Reliable Auto-Save Label names and counts are saved automatically, even when you close the app. A sudden phone call or a dead battery won't erase your data. Batch View & Direct Editing Use the list view button to see every value at a glance, and edit labels or counts directly on the spot for quick, smooth adjustments. One-Tap Reset Instantly reset every counter to 0 with a single button, so you can start a new count right away. NEW: Mode Selection & Match Mode Choose between "Normal Mode" and "Match Mode" right from the menu at launch. In Match Mode, labels 1–10 are automatically grouped into Group A and labels 11–20 into Group B, with each group's live total shown at the top of the screen in a scoreboard-style display — perfect for tracking a head-to-head team competition at a glance. Controls stay the same: tap for +1, long-press for −1. Group names can be freely renamed (e.g. "Red Team" / "White Team"), and a dedicated help screen walks you through it all. Great For ・Quick inventory checks at shops or warehouses ・Bird watching counts or traffic surveys ・Tracking workout sets or game scores ・Household inventory (like tracking what's in your fridge) ・Team scoring or head-to-head group competitions (NEW) Stripped of everything unnecessary — experience the ultimate simplicity built for one purpose: counting.
