MOJO NetCheck

A complete network toolkit in one app. No ads, no in-app purchases, no data collection.

■ Devices See everything connected to your network. The app knocks on every address, then reports each device's name, response time, and a best guess at what it is — phone, computer, printer, camera, TV, speaker.

Devices configured not to answer ping still show up, because the app knocks on their ports as a second pass. Many tools miss those entirely.

Tap any device for details, or watch it to keep an eye on whether it stays online.

■ Bonjour Printers, speakers and TVs already announce their own names across your network. This screen simply listens — it never knocks on a door — so it is gentler than a scan and gives you real device names, with plain-language notes on what each service does.

■ Quality Track latency, jitter and packet loss continuously on a live chart.

It uses real ICMP ping, the same thing the ping command on your computer does, rather than guessing from a TCP connection — which always reads higher than reality.

Choose your target: ping your router to judge Wi-Fi inside the house, or ping a server outside to judge the line to your provider.

■ Ports Check whether your port forwarding actually works.

Here is what matters: if you stand on your home Wi-Fi and probe your own public address, some routers answer themselves and some drop it — neither result is trustworthy. This app sends the test out over mobile data, so it reaches your router exactly the way a stranger on the internet would.

■ Speed Measure download, upload, latency and jitter using Cloudflare's speed servers.

Set your own data allowance per test, with separate limits for Wi-Fi and mobile data.
