Built to cut the guesswork out of live troubleshooting — is it your cabling, your settings, or the other side's gear?

■ Who it's for
Lighting, audio, and video techs — SR/PA engineers and lighting operators troubleshooting OSC and Art-Net gear on live event sites.

■ OSC Monitor
See incoming messages on any port in real time. Filter by address, and read "receiving" vs. "no signal" at a glance from a large status indicator.

■ Art-Net Receive Check
Watches ArtDmx packets on UDP 6454. Each Universe is shown as a card with source IP, fps, and channel count; tap to see all 512 channel values. Switch between a color-coded "Heatmap" view (dense grid, live-updating, see the whole universe at once) and a "RAW" view (channel number + value).

■ Network Scan
Scan devices on the same network and list IP addresses and response times. Pick any device to keep it under continuous ping monitoring.

■ Unlocked with Pro (one-time purchase, no subscription)
• Art-Net Test Send — manually send DMX values to a chosen Universe/channel to verify fixtures and nodes
• OSC Send Tester — send a message with a custom address and arguments to confirm connectivity
• Audio Test Tones — pink noise / 1kHz sine / L-R channel check for verifying PA wiring
• Video Test Patterns — full-screen color bars / grid / resolution pattern for checking projector and monitor hookups

Every receiver and sender can be started and stopped manually, and automatically stops when you switch tabs — so nothing keeps running unnoticed in the background on site.

A practical AV troubleshooting tool for lighting, audio, and video crews working on location. ## Rankings - #2,829,758 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.INTERNET` - `com.android.vending.BILLING` - `com.android.vending.CHECK_LICENSE` - `dev.dougu.avtoolkit.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` ## Similar extensions and apps - [ArtNet DMX Tool](https://chrome-stats.com/d/com.electrotas.artnettool) — 81 users - [AV Site Survey](https://chrome-stats.com/d/com.av.sitesurvey) — 27 users - [Lumikit Tools](https://chrome-stats.com/d/com.lumikit.android.wifitools) — 5,082 users - [AV Tools](https://chrome-stats.com/d/com.embu.avtools) — 204,656 users, 3.94 / 5 - [Djinni](https://chrome-stats.com/d/com.spectralbot.piltover) — 74 users - [RTA Analyzer – Pro AV Tools](https://chrome-stats.com/d/com.genartstudios.rta) — 3,803 users - [AuditAV](https://chrome-stats.com/d/com.auditav) — 13 users - [AV-Tek](https://chrome-stats.com/d/com.avtek) — 8 users - [OSCope](https://chrome-stats.com/d/jp.evenrain.oscope) — 1 users - [AV Buddy](https://chrome-stats.com/d/com.ionpixel.avbuddynew) — 619 users - [AirO](https://chrome-stats.com/d/com.arubanetworks.airobserver) — 21,938 users, 4.36 / 5 - [AVS Play](https://chrome-stats.com/d/com.avsplay.android.app) — 685 users --- Source: [Chrome-Stats](https://chrome-stats.com/d/dev.dougu.avtoolkit)
