PSiO

This application presents the advantages of the PSIO device in the shape of a pair of glasses combining light & relaxation. This device is revolutionary because it offers for the first time a real support for the mind to be in full shape all year. Sessions are available for morning, afternoon and evening. The app is designed for PSIO ambassadors as it allows them to present the benefits of the PSiO effectively in order to bring their prospects to test the device quickly. It is possible to make an appointment immediately with an ambassador. The app also gives the opportunity to test the level of alertness before and after a PSIO session. Indeed, a section proposes a reaction time test.

Verdict
The clearest difference is in-app purchases: PSiO at none against RedDose's 1. PSiO also leads on ads (none vs shown) and iOS requirement (9.0 vs 15.0). RedDose's advantage is update cadence (weekly vs every 11 months). On price and device support there is nothing between them.
