# Brainjuice vs Spirkz

The clearest difference is review sentiment: Spirkz at 100% against Brainjuice's 39%. Spirkz also leads on in-app purchases (none vs 8) and ads (none vs shown). Brainjuice's advantage is rating (4.2 vs 3.7) and ratings volume (10 vs 3). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Brainjuice sells 8 in-app purchases, starting at $2.99 per 7 days. Spirkz asks for nothing beyond the download.

Brainjuice holds the better App Store score, 4.2 against 3.7. Both are backed by a comparable volume of ratings — 10 and 3 respectively. Written reviews complicate that: 39% of Brainjuice's written reviews are positive against 100% of Spirkz's, so the app with the better star average is not the one people write more warmly about.

Brainjuice ships an update every 5 days, Spirkz daily. Both last shipped on October 31, 2026.
