# Brain vs Tango

The clearest difference is in-app purchases: Brain at none against Tango's 1. Brain also leads on ads (none vs shown) and update cadence (every 2 days vs fortnightly). Tango's advantage is iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.

Both are free to download. Tango sells 1 one-off in-app purchase. Brain asks for nothing beyond the download.

Brain ships an update every 2 days, Tango fortnightly. The most recent releases landed on October 25, 2026 and October 29, 2026 respectively.
