Perfect! 👍 ### 5/5 — Theatre Technician *2025-05-24, version 9.1* Fantastic app, must have for any theatre or live events technician! ### 5/5 — AV Buddy *2024-04-11, version 9.1* Been using this app for many years! Excellent app highly recommended. ### 4/5 — Cool app still a little way to go *2021-04-02, version 9* Crashing in the current version on the drawing, I’m still trying to work it out. Could be laid out better, buttons labelled, or maybe it’s just because it’s faulty at the moment and that’s why it’s not working properly. Measurements for outlets should be to the centre of outlets not the edge on the drawing tool. Diagrams are awesome but things like the Rj connector could be better, yes knowing the PIN number is great but it’s better to show a coloured diagram, if you search rj45 connector diagram on Google you’ll see what I mean. When doing sound tests, the button you push for the test doesn’t highlight, so if you push it you have to remember which one to press stop on because it’s not highlighted. A lot of helpful stuff in here pretty awesome I’m impressed, but still a bit of polishing to go. ### 5/5 — Fantastic update *2020-07-30, version 9* I love the new AR mode. I can see myself using this on every job I do now: walk into a room with the client and show them what it looks like. Excellent. The updated tools and cable references look great too. Only minor issue is the throw distance calculation: in my case I normally know the screen width plus the distance to the projector and need to determine the correct lens to get me there. ### 2/5 — Outdated app, video output doesn’t work *2019-10-23, version 8* I was recommended this app by a fellow professional, who had heard about it not used it. I spent my $.99, and found that the test display function does not detect even a basic display. There is some commonly available information included, is it worth $.99? I wouldn’t do it again. It would be nice to see that they would come up with a more recent update instead of a computer game, found on their website. They have a pro version, for iPad. I am not going to spend $1.99 to see that it doesn’t work as well. **Developer response:** Hello Gentle Giant II. Sorry to read that you are having trouble with AVBuddy. I'm actually in the middle of a BIG update that will include additional connectors, calculators, AV training, tools and bug fixes. I have just tested AV Buddy on my iPhone 11 and connected it to a 55" Samsung consumer-grade TV via an Apple A1348 Lightning AV adapter and a Kramer HDMI cable, it connected perfectly and all test patterns are displayed. I'll try to replicate your problem and hope to find a fix. Commonly found information is included and can be found on the internet, but AV Buddy is a way of collating that information to make it easier to find. Plus AV Buddy has a lot more, for example, AV Tools and AV Calculators. Thanks again for downloading, I'll be updating ASAP. ### 5/5 — Great training tool *2019-03-16, version 8* I just started working as a tech. This is a great addition to my tool bag. So far, it contains all the connectors I’ve used in the field. I was referred to this app from a veteran tech. I recommend it too! ### 2/5 — Pour application *2018-05-30, version 8* Less then the half of the connectors in the market ### 5/5 — Must have *2017-12-14, version 8* All techs should have this. Great app! ### 5/5 — Great app *2013-07-17, version 3.0* Lots of great info and handy functions. I tell every apprentice/rookie tech to get this app. ## Frequently asked questions about AV Buddy ### What does AV Buddy do?
