To use Shake to Play, hold the iPhone with the SIDE BUTTON facing you and shake it back and forth. The sound intensity automatically adjusts based on the strength of each shake. You do not need to hold the iPhone perfectly upright. As long as the SIDE BUTTON remains facing you, the device can be tilted up to approximately 90Β° forward. Shake detection may not work if the iPhone is tilted more than 45Β° around the Y-axis (toward either the screen or the back of the device). You can also play the selected instrument by tapping it directly on the screen.

Verdict
The clearest difference is in-app purchases: PocketPercussion at none against TN's 1. PocketPercussion also leads on ads (none vs shown) and update cadence (daily vs every 5 months). TN's advantage is iOS requirement (15.6 vs 26.0). On price and device support there is nothing between them.
