# Stack Merge vs Unblock+

The clearest difference is in-app purchases: Stack Merge at none against Unblock+'s 10. Stack Merge also leads on iOS requirement (13.0 vs 26.1). Unblock+'s advantage is ads (none vs shown) and update cadence (every 8 days vs every 2 weeks). On price and device support there is nothing between them.

Both are free to download. Unblock+ sells 10 one-off in-app purchases. Stack Merge asks for nothing beyond the download.

Stack Merge ships an update every 2 weeks, Unblock+ every 8 days. The most recent releases landed on November 4, 2026 and November 9, 2026 respectively.
