TrueEntropy uses your phone's camera to generate true random numbers derived from thermal noise. The camera in your smartphone is so advanced that it can detect even the smallest variations produced by fundamental particle physics. We capture thermal variations in every pixel of your phone's camera to create a powerful, high volume entropy random number generator. No need to move your phone - even if your phone is resting on a desktop, it is able to pick up a sufficient quantity of thermal variations to generate random numbers at a rate of 18Mb per minute. - Generate binary files for local use via AirDrop - Send entropy to a destination machine via cryptographic relays - Continuous generation mode to constantly reseed target machines

Verdict
The clearest difference is in-app purchases: TrueEntropy at none against Ear Spy Apps's 4. TrueEntropy also leads on iOS requirement (12.0 vs 14.0). Ear Spy Apps's advantage is update cadence (every 5 weeks vs every 41 months) and ratings volume (1.3K vs 11). On price, rating, ads and device support there is nothing between them.
