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. ■ Privacy No accounts, no analytics, no advertising, no tracking. Scan results stay on your device and are discarded when you close the app. Cloudflare was chosen for the speed test because some speed-test networks publish user IP addresses as permanent open data. We do not want any part of that. ■ Honest limitations iPhone does not let any app see nearby Wi-Fi networks, channels or signal strength. That is an Apple restriction, not a feature we forgot. Device watching runs only while the app is open, because iOS does not let ordinary apps keep probing the network in the background. ■ Acceptable use These tools are for networks you own or are authorised to test.
