Byter

Know exactly how much data you use, on every network

Byter shows how much internet data you use, and where. It tracks usage separately for every Wi‑Fi network, phone hotspot and wired connection, so you know exactly what your hotspot bundle went on. You also get live speed, a one-click speed test, daily-to-yearly charts, and gentle alerts when usage spikes. Everything stays on your device. No account, no ads. Available now for Mac, Windows coming…
