Hidden Paywall

You have to pay $17.99 upon downloading it if you want to anything more than watch a short video. Be up front and don’t waste peoples time.

Great app, but needs update on latest iPhones.

Please update with latest hardware!

Can’t knock this

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 :)

Wow, fixed my 3 year issue in 5 mins

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.

Amazing!

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.
