For example, I had to select an instrument before any sound would come out and this was unintuitive (3 clicks too many in non-obvious places) When I add a new track, it was nearly impossible to find how to make both tracks at the same time. Selecting the instrument you want to chord palette to play with was also impossible. Selecting multiple chords to duplicate as group; calling them verse or chorus or bridge (would be the first things I would’ve thought of) were also not possible. Great idea for (identifying which chords will go well together, based on a scale given in a song) but poor execution when it comes to actually building songs. In need of a user experience designer, so that what was obvious developers is also obvious as the rest of the world. ### 2/5 — A metronome would really help this app. *2022-03-27, version 1.3* Ideas would be easier to flesh out. Klimper helps when I have an idea for a chord progression on my morning commute, but it would really be nice if I can get a base for an entire track whenever inspiration strikes. I feel a metronome would make that easier. ### 4/5 — Good! *2021-04-19, version 1.3* I will make my own Minecraft music disc :D There are a few hard to explain and annoying bugs though ### 2/5 — Keeps crashing *2020-12-23, version 1.3* Please fix ### 2/5 — Cool App To Drain Your Battery! *2020-08-01* All functionality and coolness of this app is overshadowed by the battery eating feature. This app can use other music apps to generate sound which is neat until you close down Klimper and hours later your iOS device tells you it has 25% battery left and you haven’t touched it all day. So you go investigate in the battery tab in settings, and you find the app that Klimper loaded running in the background and somehow it’s still running. The app isn’t found in the “running apps” view for you to shut it down. There’s no clear instruction on how to shutdown this kind of app. Apple and others will tell you not to do hard shutdowns of apps.... yeah, except for when it’s killing your battery. I don’t even know if doing a hard restart will remove it. Deleting it might be the only option and reinstalling. For this reason, you get 1 star. If Apple allowed users to give a negative value of stars, this would get a -5 stars from me. If I could add a screenshot in a review, I would. I used the Moog Model 15 app that got stuck. I will promptly change my review again once this issue is resolved. I am adding a star for prompt developer support which most apps lack. **Developer response:** Hi. What app did you use it with for sound generation? Kind regards, Tobias ### 3/5 — The app is good, but could be greatly improved *2020-07-11* The app is good, and it got a lot better with the new borrowed chords implement, but some of the instruments, the guitar for example, are super quiet and barely make any sound at all, if this were fixed, I’d probably use the app a whole lot more, it’s a fantastic idea, but there’s just a lot of bugs to work out with it ### 2/5 — Mixed review *2020-05-15, version 1.3* I want to love it, but there is no METRONOME! If there is, I can’t find it. So I tried to create my own but the drum editor doesn’t line up with the Lead. Now what? ### 4/5 — For the next update *2020-04-18, version 1.3* Can we get a chord inversion button for the next update ### 3/5 — Y’all need FLEXIBILITY *2020-02-22, version 1.2.10* - like the fact that the midi sounds are lovely - hate the fact that there’s no chromatic chords - hate the fact that I can use borrowed chords - please get someone with music theory skills if that’s what’s causing the inflexibility ### 4/5 — Needs a metronome or grid *2020-01-31, version 1.2.10* I just wish it had some type of grid or metronome, or both so I can see how it loops around and be sure its in time, especially if im exporting a loop ### 2/5 — Good idea, not worth $8 *2020-01-30, version 1.2.10* There’s very limited features for this. There’s not even a basic piano sound. Also the app pops and clicks when I play sounds ### 3/5 — aight.... *2020-01-03, version 1.2.10* honestly this app is pretty much unusable as a beat maker, HOWEVER the chord pallet is an excellent tool for producers/musicians looking to come up with cool chord progressions. I hope this app gets some updates!! ### 4/5 — App is cool and useful however I think a couple added features would make it 5 Stars *2020-01-02* I use this app for intonation purposes and it’s really useful for that! However I think it would be much improved if you could implement accidentals easier, (I.e. A7#5) as opposed to chords which are strictly diatonic. Also if the app could loop while the phone is locked that would help me not kill my battery life while practicing. I mainly have been using it for a drone with a metronome so I can’t speak much on the recording functions, but they seem relatively intuitive, especially if you’re new to understanding harmony. It’s cool to be able to visually pair chords with extensions and not have to worry about intervals. I used to use other apps to drone chords but honestly this one is quick and super simple to use, once the app is open you can immediately start, it’s not like it has a long loading time or anything. ### 3/5 — Still problems with the iPhone XR *2019-12-24* I saw a review with this app not working for the iPhone X and the developer said he fixed it but I still can’t see the names of the cords due to the camera in the way. And also their need to be a feature in this app we’re you can use the piano cords instead of the names of the cords. Thank you for your time. ### 2/5 — Was sold until I bought it *2019-11-06, version 1.2.10* Can’t use the whole tone scale. Limited expression ### 2/5 — Great potential, missing features and UX issues *2019-11-02* First of all, this is immediately one of my favorite chord progression sandboxes. Don’t get me wrong. The fact that it integrates with the minimoog Model D synth app to play the notes and supports Ableton/MIDI output is extremely exciting. However, there are some significant missing features that I’d expect from an app claiming to take on the scope that it does such as a metronome, a record button, and setting the timing signature. It’s hard to tell how the chord progression will sound until you’ve already dragged the chords to the odd/uncomfortable band at the top of the screen... would honestly be easier to just record it. It’s like the length in bars is too flexible... let me pick the timing signature (e.g. 3/4) and a fixed number of bars for the loop. Really, I think the UX needs to be rethought a bit and some basic features for recording a track need to be added. With refinement, this could be the best songwriting tool an EDM songwriter could have... right now it feels like more of an open beta. Disappointing to spend $9 on what feels like an unfinished product but I would gladly invest more if the developer(s) stay active. ### 3/5 — Seemingly great... *2019-10-09* Except for persistent audio issues. Just installed on fully updated iPad Pro 11 inch, and having issues where there’s no audio until I restart my iPad, which it still happens eventually afterwards. Also synth bass causing a loud pop at beginning of note and then cutting sound. If it weren’t for these major audio issues it would be great. **Developer response:** Hi there, Reports like yours are popping up since the release of iOS 13. We are on the case! Kind regards Tobias Edit: The issue is now fixed. Did you try the update yet? ### 3/5 — Good but my ears exploded *2019-10-06* Ive been messing with this for a few weeks and i liked it. Its nice for some basic ideas if im bored ill just mess around with some chords for inspiration. But a couple of days ago i opened the app and went to hit a chord and my ears got straight EXPLODED I dont know why but the sounds are all messed up and it just blasts random noise super loud. I tried to reinstall and its the same thing. Ill never make a mediocre lo-fi chill step album at this rate smh. **Developer response:** Hi Kumu, would you please tell me your iPhone model and iOS Version? You can email me at support@klimperapp.com.  Kind regards, Tobias Edit: A fix is on it‘s way, should be available in a few hours! ### 2/5 — Not worth the money at all *2019-09-25* Since I’ve now I had the app for only 2 days, I have not gone a single time without experiencing buggy issues. The app crashes when being used, plays distorted tones and overall has a frustrating to use operation system. I love the overall concept but would hate to see other people’s hard earned money go down the drain when having the same technical issues I had after spending a hardy $8.99 for an app that seems as if it’s in an early stage of production. **Developer response:** Hi Nic, sorry to hear about your issues with Klimper. I am unable to reproduce the described issues on my test devices at hand, so would you mind telling me your iOS version and device model to help us fix it? In the mean time, please consider requesting a refund: https://9to5mac.com/2018/09/21/how-to-get-a-refund-for-the-app-store-or-itunes/ I would love to provide a new version for free (App Store gift) as soon as fixed, so please contact me at tobias@polydigm.de. Kind regards Tobias ### 3/5 — Needs proper au support with midi! *2019-08-25, version 1.2.6* Needs MIDI out for other iOS apps! This great, very fun and inspiring, needs much better inter app midi implementation, especially a way to sync the transport! ## Most critical reviews (10 lowest-rated) ### 1/5 — Absolute trash *2021-04-30, version 1.3* This is by far the worst music app I have ever used. Customer service is non existent and with each use, there’s a higher degradation of performance. ### 1/5 — Not satistified *2021-03-10, version 1.3* I would like a refund. I was expecting way more flexibility within the app. The app is set up pretty basic. ### 1/5 — Klimper doesn’t work *2021-02-25, version 1.3* The phone app loaded ok and played ok for a while and then it started producing a very distorted chord sounds and finally it just quit and now doesn’t play at all. Don’t waste your money. ### 1/5 — Buggy, clunky interface *2020-12-26, version 1.3* Skip this one - not worth 8.99 to do something you can already do in free apps much more easily. Pick a chord progression or looper free app and it will save you some $ ### 1/5 — Distorted audio after first use *2020-11-15, version 1.3* This app is horrible! Started out good for first song until I opened up a new project and the midi sound has crackles and weird noises. Then chords won’t play as quarter notes only whole or half time when pressing the chords. More chords are need .... take a look at “Suggester app”... ### 1/5 — I'd like a refund *2020-09-01, version 1.3* Used it for a few minutes to check it out. Absolutely not worth the money. Very basic and extremely limited control absolutely should be a free app or non existent. ### 1/5 — Needs improvement *2020-02-07* Drum pad takes up to much of the screen. On iPhone XR you can’t see about 3/4’s of it. Also constantly getting stuck on track tabs with no clear way back to the one you want to work on available. Constantly end up tapping everywhere on the screen hoping something will happen. Pinch zoom rarely functions as intended and the crop/delete/cut feature constantly off screen/un-tappable. ### 1/5 — Seemed like a cool idea... *2019-06-01, version 1.2.3* Seemed like a great idea, I could start a session anywhere and finish up at my main workstation but upon opening the app I had no piano, Rhodes or and anything that resembled a key played instrument, there where only pads and synths available... not very good sounds to find chords and chord progressions. Didn’t bother going any further than that. Refund please. And if there in there somewhere buried they are way to hard to find and still, ima need my 10 spot back g lol.. **Developer response:** Please look again, it‘s not „buried“. You can select instruments in the track list by tapping the instrument icon. Piano and Rhodes are available there. If you still want a refund, please contact me at support@klimperapp.com. Kind regards Tobias ### 1/5 — Issues *2019-03-22, version 1.1.16* The exporting feature is confusing. First, I can’t figure out how to label my songs. Then once exported the beginning of the tracks cut off in the first chord. This doesn’t seem like a completed work because of these issues. Please fix this. I like everything else so far and I’d hate to have to ask for a refund. ### 1/5 — A one out of 5 is too high of a rating *2017-12-25, version 1.1.3* DO NOT BUY THIS APP ITS RETARDED BEYOND THE TIME I HAVE TO WRITE ABOUT. I’ll say this. The piano roll has no note names. It the app forces me to create my own chords based on a general C7 chord for example. It simply has a lighter colour on The squares that harmonize with a general C chord. THATS IT. The worst part is the app does not tell me ANYWHERE on the board,on the piano tile, on the side, or on the top, on the bottom, NOWHERE does the app label the name of the note I’m about to add to my supposed “chord”. NO NOTE NAME OR LABEL TO BE SEEN ARE U KIDDING ME DEV? Try playing a drum kit piano roll with no names or even a mark for C3. NOTHING. It is the 100000000% by far the absolute WORST APP IVE EVER SEEN PAID OR FREE AND IT COST ME TEN CANADIAN DOLLARS U US RETARDS. Canada !! DO NOT BUY THIS APP!!! DON’T EVEN DOWNLOAD IT IF ITS FREE!!! ## Most praised reviews (10 highest-rated) ### 5/5 — Connectivity *2022-11-17, version 1.3.2* Could u guys enable a feature to allow project files to be transfered from iPhone to Mac Not just the midi files? ### 5/5 — Worth it *2020-12-27, version 1.3* I don’t know how it’s only rated 3 stars. You can make some crazy stuff on here. Although I wish they’d add more sounds, I love the way it is. ### 5/5 — Great Program *2019-12-05* It’s really good but it needs some work, some of the submenus are not visible because of the way iPhone 11 designed the screen, it cuts out, also the looping part doesn’t let to be adjusted, there’s glitches of dragging the chord and not seeing it properly but playing it! ### 5/5 — No change in Scales *2019-08-08* The app is cool. Was hoping that they could at least allow to change SCALES!!!!! Maby next update? I’m going to give you guys 5 stars for now. But if I don’t see an option to change scales soon this opinion of mine will probably change. Other than that great job it’s really cool. I just thought that would of been something that you guys would of done from the very beginning. ### 5/5 — Fantastic App *2019-04-09* It’s great. Thank you. The only thing I would suggest is making the piano roll notes easier to extend and make smaller. Sometimes it’s difficult to quickly put the notes exactly where I want. Otherwise it’s very intuitive and a pleasure to use. And add more instruments!! ### 5/5 — 10 minutes in this is already an indispensable tool. *2019-03-06* Was sceptical, but decided it was worth it. I compose on my phone a lot and am always looking for a way to streamline writing. With this setup I think I can pump out great chord progressions with ease. This is a must have. ### 5/5 — Exactly what I need *2018-07-23* I have been searching for something like this to replace my piano apps and voice memos. I am a composer and spend most my time writing in my studio; however, I needed a quick way to record ideas and compose snippets on the go and at the time an melody pops into my head. Instead of singing, humming into a voice memo or playing my piano app and trying to memorize the part real quick. Anyway, I would only suggest to the dev to add a more practical way of changing tempo and making an option for triplets at a smaller level. You can write quarter note triplets but nothing smaller, forcing you to redesign your note layout, and adjusting the bpm. Regardless, this app is still a perfect app for what I intend to use it for but I could see it being very limited if people were to use it as a platform for full composition. ### 5/5 — Love It, but . . . *2018-06-24, version 1.1.9* I do love this app and the tunes it is helping bring out. One little issue - it crashes when I try to export audio. ### 5/5 — Love the chord palette *2018-05-01, version 1.1.6* This is probably my favorite app for experimenting with chord progressions. Quick and easy to try stuff out, especially with the new chord track. ### 5/5 — Very good indeed! *2017-08-17, version 1.1.1* After the lastest update and the fact that the developer is committed to improving Klimper is a bonus in my books. I'm having a very creative time with this app. Thanks for bringing this to my iPad!! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
