Sleek, efficient, and responsive, TuneWave is the no-nonsense utility that lets you tune your instrument quickly and easily. TuneWave puts everything you need front and center for optimal visibility and glanceable feedback. It can transpose if you’re using an instrument that requires it, and it can even adjust the base frequency to fit your needs. You can even adjust the input volume based on your instrument or surroundings for the best possible results. Forget big dials and fake wood, just get in, get ready, and then get back to your music. "the design is modern and the app has few distracting bells and whistles...minimalist and speedy." - The New York Times
KR8
Read full descriptionHide full description
KR8-0 is a drum machine for live performance. It runs a step sequencer with 16 to 64 steps, four drum kits, per-channel mute and solo, per-channel volume, and a BPM range of 40 to 220. The audio engine runs on a dedicated thread separate from the UI, so the tempo holds regardless of what's happening on screen. Four kits are included. The default kit is synthesis-based: each sound is generated from mathematical waveforms and envelopes computed in real time, with no sample files involved. The three additional kits are sample-based, using recorded drum sounds loaded from audio files on the device. No internet connection is used at any point. No account is required. No data leaves the device.

Verdict
The clearest difference is update cadence: KR8 at every 4 days against TuneWave's every 5 months. TuneWave's advantage is price ($0.99 vs $2.99) and device support (5 vs 1). On ads, in-app purchases and iOS requirement there is nothing between them.
