ThumbJam is a powerful musical performance experience. You get over 40 high-quality real instruments multi-sampled exclusively for this app. Hundreds of included scales allow you to effortlessly play in any style from rock to classical, whether you are a musical novice or a seasoned professional.

Jordan Rudess, the world-renowned keyboardist for Dream Theater says:

"ThumbJam stands at the very top of the overcrowded music app world. The sounds included absolutely rival those found in pro instruments and making music on the app is a total joy. The only problem I have with this app is that I did not make it myself! Luckily, I'm able to work with the developer and offer a few good feature ideas as well as some choice sounds from my personal collection!"

Even if you've only played air guitar, ThumbJam lets you sound like a pro. Pick an instrument and jam -- with all the scales to choose from you'll never hit a wrong note. The high quality instrument samples will make you sound like you just skipped years of music lessons.

For the performing musician, this app is awesome for soloing on an instrument you didn't bring along. Play in any key, any style -- go from a string ensemble to a wailing guitar. ThumbJam was developed and tested by musicians to feel and sound like a real instrument. You'll be surprised at how expressive it can be, make sure to check out the videos and audio at

ThumbJam makes use of tilt and shake to add vibrato, tremolo, note bends, and volume swells for more realistic and expressive results. It supports up to five (eleven on iPad) simultaneous touches and up to 24 voice polyphony, for each of up to 8 loaded instruments! Delay and stereo reverb add depth to the sound, and a resonant lowpass filter gives you more tone shaping power. Put on your headphones or plug in to your home stereo to experience some of the highest quality instruments in the App Store.

Build your own loops from the ground up or import your favorites and jam from there. Layer as many loops as you want, with different instruments for each. Export your loops as audio files or Ardour DAW sessions via WiFi. Copy and paste audio from other apps using Sonoma Wire Works AudioCopy/Paste as well the general pasteboard, via email, AudioShare, iTunes Document Sharing, or open directly in another application. Supports Audiobus and Inter-App-Audio for streaming sound to/from other apps in real-time, including state save/restore with Audiobus2.

Want to jam with your friends? ThumbJam lets you broadcast tempo, key, and scale to other nearby devices via Bluetooth so you can be in sync live. Even better, you can use it as a MIDI or OSC controller over WiFi, with any CoreMidi compatible device, or other apps on the same iOS device with virtual MIDI, or play ThumbJam with other hardware or software MIDI controllers or apps!

The app includes a huge variety of scales, from western to eastern. Save your favorites for quick access, or create your own in-app. You can even import new scales in the Scala format for complete flexibility.

You can also record your own instruments using a built-in or attached microphone, or from file import.

Customer Reviews

Great app and good customer service

I downloaded this app when it went on sale for .99 just recently. And I am kind of sad I have been missing out on this for so long. Haha. I did end up buying it for a friend at the 8.99 price because it was worth it.

I had also had some questions about setting up the scales and presets to work with the new Auug case/holder and they were quick to help me out. Got all my questions answered in a timely manner by email (being in business I expect 2 days or less response time). Looking forward to playing around with this app more.

The only bad thing I have run into so far is that the Bluetooth transmission is a little slow for using the app over a Bluetooth speaker or receiver. Only tested it on a mpow Bluetooth 4.0 receiver, so it could have been the receivers issue.

The App That Keeps on Giving

One of those, ‘only on a touch screen is this possible’ type apps that make you happy your purchased your iDevice.

Beautiful sounds and easy scales are really only the tip of the iceberg with Thumbjam. There’s a looper. There’s an audio to MIDI converter. There’s split screens (up to 4 instruments on screen at once). It works as an 8 channel multitimbral sampler. It will allow you to play the white notes on your external keyboard and route that MIDI info to another app while TJ superimposes its scale on it (you have to try this to believe it). It’s a sampler. It plays well with every single iOS music making standard including multiple AudioBus outputs. And. So. Much. More.

If you own an iDevice and like to make music there’s absolutely no reason for you to not purchase this immediately. You’ll love it.

an entire instrumental world in your pocket

I have had ThumbJam for a few years, since my iPhone 4, and it is still one of my favorite apps and a rare gem that I have bought for several other people because I am so enamored with it.
Not too many but there are a few instruments that play like the real one might. And I can’t say this is something you could play in a band. But if you like to explore instruments, especially if you have kids, then this is one of the best out there for just the sheer number of instruments available and the quick and easy way of switching from one to another.
If you have kids I highly recommend this, and if your don’t it’s fun to play with.
