# ABCDEF vs Brainstorm

The clearest difference is in-app purchases: ABCDEF at none against Brainstorm's 4. ABCDEF also leads on ads (none vs shown). Brainstorm's advantage is update cadence (every 3 months vs every 12 months) and iOS requirement (12.0 vs 26.0). On price and device support there is nothing between them.

Both are free to download. Brainstorm sells 4 one-off in-app purchases. ABCDEF asks for nothing beyond the download.

ABCDEF ships an update every 12 months, Brainstorm every 3 months. The most recent releases landed on October 7, 2026 and October 3, 2026 respectively.
