"EEG Waves" is a system designed to conduct sessions during which data on the user's emotional activity (states of emotional relaxation and concentration of attention) are recorded. Based on the obtained data, a graph of the dynamics of changes in wave activity, emotional state and a circular diagram of rhythms is plotted. The application provides the ability to export data, save and view the results of sessions, mechanisms for filtering them by dates and custom ranges. The mobile application is part of the "EEG Waves" system. You must purchase a MINDO device (or BrainBit) to conduct sessions. Detailed information about the system can be found on the official website of the manufacturer.

The clearest difference is price: Fatigue Test TalTech at Free against EEG Waves's $24.99. Fatigue Test TalTech also leads on update cadence (weekly vs every 12 months). EEG Waves's advantage is iOS requirement (13.0 vs 16.2). On ads, in-app purchases and device support there is nothing between them.
