# Brainiac vs WhatsThat

The clearest difference is rating: Brainiac at 4.8 against WhatsThat's 2.0. Brainiac also leads on ads (none vs shown) and ratings volume (262 vs 17). WhatsThat's advantage is review sentiment (71% vs 33%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Brainiac sells 5 in-app purchases, starting at $6.99 per 7 days and WhatsThat sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Brainiac holds the better App Store score, 4.8 against 2.0. That said, the two scores are not equally well evidenced: Brainiac has 262 ratings behind it against 17, so its average is the more settled of the two. Written reviews complicate that: 33% of Brainiac's written reviews are positive against 71% of WhatsThat's, so the app with the better star average is not the one people write more warmly about.

Brainiac ships an update every 8 days, WhatsThat every 5 days. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
