Multimeter is a menu bar app for people who glance at their Mac's numbers all day. Your battery gets a real meter: charging state, time to full, time left, health, cycles and temperature in one click. Add watts, CPU, memory, network, fan speed or your Magic Mouse's battery next to it, each drawn the way you like: an analog gauge with a springy needle, seven-segment LCD digits, a sparkline, a ring, or a row of hearts. Send your own numbers with a multimeter:// link from Terminal, Shortcuts or cron, or point a meter at a JSON URL, a file or a shell script. Pick one of 35 faces for each meter, or make your own with Create Face. Set warning and critical levels that turn a meter yellow or red and can notify you. Save sets as themes. About 3% CPU for five live meters. No account, no tracking. $19.99 once, no subscription. macOS 13 or later.
