Be up front and don’t waste peoples time. ### 4/5 — Great app, but needs update on latest iPhones. *2024-04-03, version 1.0.11* Please update with latest hardware! ### 4/5 — Wow, fixed my 3 year issue in 5 mins *2023-04-28, version 1.0.11* 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. ### 4/5 — Great idea *2021-07-30, version 1.0.10* This app is a great idea. But it’s very hard to slip the audio in small increments. It would be better if sliding your finger back and forth moves slower for better precision. ### 1/5 — Doesn’t work *2019-12-02, version 1.0.8* Spent nearly $20 on this app, and when I go to upload a video, it crashes. Every time. ### 1/5 — Ridiculously overpriced *2019-06-15, version 1.0.8* This app is completely useless without purchasing the full version. Which is fair enough: they offer a demo for free for you to see how it work but then if you need to edit your own videos then cough up. However, I’d expect a cost of £1.99, maybe £2.99. If they added ways to make the syncing more precise I might even pay £3.99 for this app. But this app costs £19.99 to purchase! This is an extortionate amount of money for an app that is very imprecise and difficult to use, and is insulting to me as a consumer. Take the price down. Then maybe it would be worth getting. ### 1/5 — Horrible app *2017-12-24, version 1.0.7* Just awful ### 4/5 — Works like a treat. *2015-10-20, version 1.0.7* Very easy to use, but since the interface is not build to be very precise with your fingers, the results are not absolutely accurate. I hope the developer gives an update where you can adjust the soundtrack easier. The UI deserves a fresh look as well. Nevertheless a great tool, but a bit dusty. ### 4/5 — Fantastic app... *2015-01-19, version 1.0.7* Please release a version that does 23.98 and 29.97. Also after you unlock would be great is audio slide was easier... But really all around fantastic app. ### 5/5 — Synced up Audio/Video perfectly in <60s on first try *2014-05-22, version 1.0.7* I got Audio/Video sync right on the money in less than 60s on my first try. (I’m running a PC-based convolver with a lot of buffering prior to the speakers, and in my case the audio was 2150ms ahead of the video.) ## Most critical reviews (10 lowest-rated) ### 1/5 — App crashes *2022-02-10, version 1.0.10* It crashes every time I try to choose a video from my library. ### 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. ### 1/5 — Tricky free to use *2022-01-06, version 1.0.10* Functionality will be unlocked only for payment, For free you have video how it would work if you buy it. ### 1/5 — Not free *2021-06-26, version 1.0.10* In app purchase ### 1/5 — Whatever username is available *2021-01-20, version 1.0.8* I’ve just paid £20 and this thing quits as soon as I hit “record”! How do I get my money back?! ### 1/5 — Can’t open from library *2021-01-18, version 1.0.8* This app is useless without the ability to open a video from library, but it crashes each time I press the button. Please address this immediately, I would never have paid 20 quid if I knew this operation was unavailable ### 1/5 — Garbage rip off App *2020-12-09, version 1.0.8* This is barely an app ...especially if you paid the 19.99 for it. It’s just one screen and you cant save your videos or send or even listen while editing. GARBAGE SCAM. I want my money back! ### 1/5 — Over priced *2020-05-26, version 1.0.8* 20 bucks for something you can do in any video editing software. That’s a hard no. ### 1/5 — Crashes on opening photo library *2020-05-24, version 1.0.8* Crashes instantly when trying to open library to select a video. Unusable. ### 1/5 — It crashes *2020-04-19, version 1.0.8* How do I get a refund? Just downloaded it today and it crashes when I try to access my camera roll...every time. What gives?? ## Most praised reviews (10 highest-rated) ### 5/5 — Simple and affective *2026-08-03, version 1.0.13* This app is very basic, feels overpriced for what it is but it does do the job and useful tool have. ### 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 :) ### 5/5 — Amazing! *2023-03-05, version 1.0.11* 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, version 1.0.11* 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, version 1.0.11* 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! ### 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! ### 5/5 — Brilliant App + Great communication with the app makers *2021-01-19* I use this app at the beginning of every project. It removes any doubt as to whether the editing gear is playing back in sync - such a fantastic app - well worth it. I’ve not seen a better (or easier to use) app for checking sync - I even used it at home to sync my home theatre! Looks like a lot of hard work went into marking this app. Clever people. **Developer response:** Thanks Jonno! ### 5/5 — Absolutely essential for home theater buffs *2020-07-21, version 1.0.8* If you want you get your audio sync with your home theater just right, this is the app for you. I’ve learned I can’t entirely trust my eyes when calibrating A.V. sync, and those little discrepancies add up over time and can indirectly affect your enjoyment. The price may seem a bit expensive but honestly for how accurate it is (within only a couple ms in my tests) compared to professional tools it’s incredibly worth it, both for the improvement to your home theater and for your own piece of mind knowing your stuff is set up properly. That being said, the app shows its age and could use a little work in some areas. The directions are a little convoluted (I didn’t even know how to play a video I recorded - the obvious solution was to tap anywhere on the screen) and require a little bit of extra calibration at the beginning since you need to set the inherent lag for your device manually after checking their website for the correct value. It also isn’t optimized for modern devices, with stuff on the edge cut off by the “notch,” which looks pretty bad but doesn’t impact the utility. In the end though, this is the most useful app I’ve ever bought. It’s made my home theater better, it’s made my friends’ home theaters better, and I’ve learned a ton in the process. A few bonus tips: After calibrating the inherent device lag, be sure to test it first by recording a video of your hand tapping on something (preferably reflective) and making sure the wave spikes match up with the exact point you make contact. This should make you confident that this app does what it says. Calibrating distance adds ~1ms for each foot away from the source. This isn’t really necessary for home theater stuff, unless you’re setting up an outdoor theater. Grab a Spears and Munsil Benchmark Blu-ray or UHD and use their A.V. sync tool for best results in a Blu-ray player. YouTube also has videos in various quality you can use (such as one called Lip Flap), but keep in mind that calibration will be based on the source (that is, if you calibrate based on a YouTube video, your sync is going to be a bit off on a Blu-ray with the same settings). It’s impossible to get a one size fits all A.V. sync solution due to different sources all containing different amounts of lag. For example, Dolby True HD is anywhere from 10 - 40 ms slower than DTS Master Audio, and upscaling a 1080p Blu-ray on a 4K UHD player can add another 20 ms or more to your sync adjustment. Thankfully our brains can adjust for a fairly high amount of discrepancy here, so I recommend adjusting your audio delay based on the highest quality media your player supports, and that will likely be close enough to everything else that you won’t notice the difference. You could theoretically use this app to get the ideal setting for every type of media, write it all down, and set it perfectly every time, but the cost to your sanity is likely not worth it. If I haven’t made it clear enough, I love this app. If you care about making your home theater the best it can be and you don’t have access to fancy ISF calibration tools, you need this. The price of entry may seem on the high side for an iOS app, but its usefulness is unquestionable. ### 5/5 — Well executed! *2015-01-29, version 1.0.7* Amazing concept and great implementation. While not 100% accurate due to the limited frame rate, is a life savior in Pro Tools setups with an external screen. ### 5/5 — A must for all soundeditors who owns an iphone *2014-06-01, version 1.0.7* This device is very usefull and works very well. 12Dollar if the only comparable device costs 400 is really not to much. Thnx very much for this app! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
