SoulTuner provides a simple way for you to explore the effects of binaural beats where each ear receives a slightly different frequency. This is said to produce feelings of relaxation or greater focus depending on the settings. Use the knobs to adjust the base (Carrier) frequency to one that feels right for you. Optionally, add harmony voices and reverb for a fuller sound or listen to a complex harmony of drones all by itself. Features —Pure binaural sine waves, one for each ear in headphones —Music toggle to switch to musical notes instead of raw frequencies —Toggle to swap left and right for binaural sources —Up to 25 additional color-coded interval harmony drones over two octaves (but less is often more) —Add automated panning to gently move drones around —Add reverb for fuller spacial sound —Change harmony drone voices —Create ambient noise of various pleasing types: Pink, Brown, Green, Gray, White and add a slow sweep to change it —Add a low slow pulse synchronized to the other audio for extra relaxation —Use a timer to turn everything off after awhile, good for a sleep setting —Can run in the background while you do other things or have your device screen off Uses —Explore relaxation and focus properties of binaural audio —Find frequencies that feel right for you —Use the massive drone stack out to a recording device

Verdict
The clearest difference is price: SmartPlank at Free against SoulTuner's $0.99. SmartPlank also leads on iOS requirement (16.0 vs 18.6). SoulTuner's advantage is update cadence (every 5 days vs every 4 months). On ads, in-app purchases and device support there is nothing between them.
