Be up front and don’t waste peoples time. **Developer response:** There is nothing "hidden", it's all there in the description. ### 4/5 — Great app, but needs update on latest iPhones. *2024-04-03* Please update with latest hardware! ### 5/5 — Can’t knock this *2023-07-06, version 1.0.11* I’m a home user who bought this to fix the audio sync on my AV receiver. I really should knock this for being objectively expensive for what it is, but the one thing it does do it does absolutely perfectly, and i no longer have to worry if I’ve messed the settings up calibrating it by eye, which i’ve been trying to do on-and-off for literally years! Worth every penny just to not have to deal with that :) ### 4/5 — Wow, fixed my 3 year issue in 5 mins *2023-04-28* Ok, I was annoyed at $20, but oh man is it worth it. UI could use work and the slider bar took a min to understand, but it gets the job done. I’ve been dealing with a sync issue ever since I replaced my TV and receiver, never got the timing right. 5 mins with this and it fixed my issue instantly. 100% recommend to anyone having sync issues. ### 5/5 — Amazing! *2023-03-05* I never write reviews, but there’s not many for this $20 app. Saved me SO much timing calibrating lip sync on my new receiver. Read the instructions to line up video and audio and it gives you the extract millisecond offset! Love it. ### 5/5 — Great app for syncing home theater *2022-10-11* My home theater does quite a bit of audio processing and my TV has an unknown amount of input lag. This app helped me sync audio and video quite quickly. It is an expensive app for what it is but I didn’t see any obvious alternatives. ### 5/5 — Invaluable A/V sync tool *2022-04-06* Have I been using this app for the full nine years it existed? Yep. Have I pitied Android users who cannot use it? Check. From the same company that brought you stellar time-saving tools like Waverider and Defaulter, this app isn’t just a must-have, it’s an industry changer. Simple and effective, anybody working in post-production who isn’t aware of the necessity of sync confirmation can get lost. These guys make it easy. Do yourself the favor and acquaint yourself! ### 1/5 — App crashes *2022-02-10* It crashes every time I try to choose a video from my library. ### 5/5 — Brilliantly simple solution *2022-01-27, version 1.0.10* This is a fantastically simple solution for sync alignment of audio and video monitors in post production. An absolute bargain at the price! ### 1/5 — Scrabbled graphics on iPhone SE *2022-01-25, version 1.0.10* On the iPhone SE the read out of the frames offset overlaps with the word Distance, making it impossible to use the app. Additionally the app crashes when trying to access the library. ## Frequently asked questions about Catchin' Sync ### What does Catchin' Sync do?
