Verdict
The clearest difference is review sentiment: Brain at 100% against EV Battery's 0%. EV Battery's advantage is rating (5.0 vs 3.0) and in-app purchases (none vs 1). On price, ratings volume, ads and monetization model 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
Both are free to download. Brain sells 1 in-app purchase, starting at $1.99 per month. EV Battery asks for nothing beyond the download.
EV Battery holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 0% of EV Battery's written reviews are positive against 100% of Brain's, so the app with the better star average is not the one people write more warmly about.
EV Battery ships an update monthly, Brain every 21 months. Both last shipped on November 3, 2026.
