"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.

Verdict
The clearest difference is price: Mendi App at Free against EEG Waves's $24.99. Mendi App also leads on rating (4.4 vs 2.5) and update cadence (every 10 days vs every 12 months). EEG Waves's advantage is review sentiment (100% vs 77%) and iOS requirement (13.0 vs 16.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Mendi App is free to download; EEG Waves costs $24.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Mendi App holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Mendi App has 454 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 77% of Mendi App's written reviews are positive against 100% of EEG Waves's, so the app with the better star average is not the one people write more warmly about.
Mendi App ships an update every 10 days, EEG Waves every 12 months. The most recent releases landed on October 17, 2026 and October 6, 2026 respectively.
