I have the latest iPad Pro that can more than handle just about anything I throw at it. I bought this based on ratings. It doesn’t show up in Audiobus in the effects or any other slot. The app says it works in Audiobus. It doesn’t. I restarted the iPad, deleted and reinstalled. Nothing. I feel like I was ripped off. **Developer response:** Edit: we are unable to replicate this error on our test devices.

Had to uninstall. **Developer response:** This was fixed in version 1.10.

I throw one on every track just so see the spectrum analyzed and throw a quick low pass or high pass. Developer is active on the forums and very decent guy, definitely worth supporting. It is good to find good bread and butter utilities like these with a good clean interface. Totally worth it. ### 5/5 — As good as goose eq but without the subscription model *2019-06-19* Couldn't find an iPhone auv3 that was lightweight yet powerful. These blue mango folks are killing it. Goose eq was good too but I'm not subscribing to a eq plugin (lol). This is the one for me. Sounds fantastic and lots of control. Stable and also has frequency visualizer for better adjustment. 👍 ### 5/5 — My go-to EQ *2019-04-12* In terms of sound quality, it’s the same as the EQ that comes with your DAW. What makes this one stand out above the rest is the UI. It’s the only EQ that is easy to use in small windows like the ones you get on iPhone in portrait orientation. It has the right amount of control so that I can quickly find the sound I need. The main reason it’s so fast is that it gives me a carefully limited set of musical options, instead of filling the UI with rarely-used buttons and switches along with unusual filter shapes. If you need really advanced options and esoteric EQ curves, this is not he app you are looking for. But for everyday EQ adjustments, this is the fastest, easiest way to do what you need. ### 5/5 — Really good *2018-10-27* This is so intuitive and cuts down the time spent EQing massively. The only issue is that sometimes the state is not saved, which means you have to do it all again each time you load a track. It doesn't do it all the time but often enough for it to be annoying. But, still, a stroke of genius overall. Love it. Edit: for some reason the developer keeps updating it, which is good, but the results are always that the app is even more unreliable than before, which is bad. It's reaching the point of being unusable now because I'm loathe to keep reloading EVERY INSTANCE IN AU3 because it has crashed upon loading. The latest update is a disaster. I'm just annoyed with it now and may have to look for a more reliable option. Sad, though, because this is - when it works - the best out there. Edit: problems now resolved, which means this is a great app. Buy it! ### 5/5 — Very good. *2018-07-18* I think this is a really great EQ. Integrates well into GarageBand, and offers me a little more control than the native EQ. Very easy to use. Recommended. ### 5/5 — Nicely designed *2018-07-08* While other EQ’s I’ve used have been quite fiddly and more suited to using a mouse this one is remarkably simple in operation but just as effective. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
