Internet Speed Monitor

A probe returns download speed, upload speed, ping, jitter and a steadiness score from 0 to 100. Each result is saved to a private log with its time and link type. Filter the log by WiFi or mobile, open a reading, delete one, export history as CSV or erase everything. Optional auto checks run on a timer while open. Trends charts download, upload, ping and steadiness across 24 hours, 7 days, 30 days or the full history, and shows whether the newer half of the window runs faster or slower than the older half. Compare sets WiFi against mobile data and splits readings into night, morning, afternoon and evening, which exposes the weakest part of the day.
