See your network the way it really is
Professional-grade network testing on Android — live health verdicts, drive-test recording with notes, and a web replay that takes you straight to the issues.
Free on Android during early access. Already testing? Open the web viewer.
Built to tell you, not to be watched
Health at a glance
A live verdict — cellular, Wi-Fi, Bluetooth and GPS graded against engineering thresholds. Green means go; amber tells you where to look.
Drive-test recording
One-tap recording with timestamped notes. Every metric, every event, every annotation lands in a clean JSONL session log.
Time-navigable charts
Threshold zones behind every line, real time axes, and a crosshair that tells you when — not just what.
Events on the chart
Drops, handovers, degradations, and your own notes are marked exactly where they happened. Cause and effect in one picture.
Web replay and sharing
Upload a session and scrub through it on the web — maps, workspaces, and a jump-to-issue list. Share a link, not a spreadsheet.
Configurable to the bone
Bento workspaces, custom thresholds, iPerf3 test plans, LAN tools, and a terminal. Built by network engineers, for network engineers.
From street to insight in minutes
The workflow that used to need a licensed drive-test rig, a laptop, and an afternoon of post-processing.
Record
One tap. The app grades cellular, Wi-Fi, Bluetooth and GPS live while logging every metric each second — drop timestamped notes without breaking stride.
Upload
Straight from the phone the moment you stop. No cables, no CSV wrangling, no desktop tooling — a link and an access code.
Analyse
A replay built like a trading terminal: scrub the timeline, click straight to issues and notes, and see every metric on charts, maps, and distributions.
And the part that usually costs five figures a seat: the whole loop is free during early access — staying affordable is the point. Accounts that keep uploads longer start small. See pricing.
