Gap Click by Benny Greb

This app is an amazing tool to practice metronome displacements. After some time music feels like high-resolution and slow motion, allowing to play offbeats in a controlled way. The concept is super simple and most effective. I love it. Yet the app is partially buggy and partially clumsy. If you use the app and someone calls you, the click sound will be replaced by something muffled, you will have to restart the app to get your click sound back. This bug should have been found through proper testing before publishing the app. Colors are a question of taste, but this green and blue and even gradients look like designed in 1980. The notation of the 16th notes for the gaps is unnecessarily complicated: instead of dotted 8th note better show 4x 16th notes. Using Intersecting circles for overlapping interaction controls (here the bpm control with time signature and tap) is questionable UX design. The click sounds are not cut properly and have a distorted reverb tail, annoying when playing with headphones. Improvements I would love to see for future updates are a help section to explain how to use this method systematically (I guess this would help every single user) and for beginners a visual indicator for the beat quarter notes. Just for clarification: For me this app is a must-have. My critics are carried by love only. Maybe it helps to improve the app or encourage users to give it a try.

I heard about this app from Reddit after I searched for "best metronome for guitar". The gap is so good for training myself to maintain a tempo! The interface is very intuitive except for the tap circle, but I just learned what that does from reading a review on my way to write this one. I went and tried it really quick, and it's perfect! So useful! I've only used the default sound because I find it pleasant, so no need to mess with it. By contrast, I checked out some youtube BPM videos yesterday, and the sound effect was so awful, I just couldn't. I love that it keeps playing even if the app is put in the background, and it even plays while the Voice Memo app is recording! (The metronome will be on the recording though.) The only thing I don't see that I would like to have is the ability to store tempos (so I can quickly grab the tempo I was last using for each of the different songs I’m practicing).

The fact that this gives you nearly all the functionality of the $100+ metronomes of yesteryear in a snappy little app? Brilliant. Easily makes it way into my rotation of practice aids!

I don’t even really leave reviews like that, but this has everything I would need in a metronome. You can even tap a rhythm. I’m happy I found this so early into studying guitar.

I haven’t used Gap Click all day, but it’s consumed 23% of my phone’s battery. Hopefully it’s not doing anything nefarious.

While this may not have the bells and whistles of a really nice metronome, this thing is still an amazing tool. I saw instant improvement in my soloing and fills and just timekeeping in genera…. after a few practice sessions. it has proven itself to be an Absolutely essential practice tool going forward

I enjoy the app, but I feel that it has a lot of holes. If I have the metronome, in 4/4 time, play a measure of quarter notes, then leave 3 measures of rest it ends up dropping some beats in the measure that the click plays; it might play … 2 3 4 or 1 2 3 … adding a beat of silence when there should be a click. When it comes to options I feel like it should a greater range for tempo, it should go up to 400, it’s not necessary since no one needs quarters going and 400, half notes would be better, but it would be expected for the app to have a large range of tempos instead having to use, for example, 200bpm to imply half notes at 400bpm. Also when using a speaker it sometimes just plays a low drone, making restart the app until it functions properly.

I love this app. This is something that I’ve been looking for for a long time. The design is super simple, and makes the app very easy to figure out. I love the changing color display as well. My only complaint is the lack of features. I hope in the future that more time signatures can be implemented, as well as more subdivisions in the “content” section. This would make the app all the more useful. It would be nice if you could add more than 8 bars as well. However, despite these downsides, the app is incredible, and such a great tool for any musician.

This app would be wonderful if you could leave the app or lock your phone, and the metronome kept playing in the background. Sometimes I need to reference a photo of sheet music, save battery by locking my phone, or use the camera on my phone to record myself, and I’d love for the metronome to keep running when I do those things. Hoping this is an easy fix that gets added soon!

This is a great app! By far Benny is one of the most influential drummers from the last decade. I do like the GAP concept and how it helps to improve timing and consistency. I just wonder if they can add a timer in the settings menu. As a musicians is crucial to work on a variety of things. And being able to keep on track how much time we focus on one specific thing, helps to improve time practicing.
