Verdict
The clearest difference is ads: Authorized Unlock at none against Brain training calculator's shown. Authorized Unlock also leads on iOS requirement (12.0 vs 15.8.3). Brain training calculator's advantage is update cadence (every 2 weeks vs every 4 months). On price, in-app purchases and device support there is nothing between them.
