# Quantum vs PrimePop

The clearest difference is in-app purchases: Quantum at none against PrimePop's 3. Quantum also leads on ads (none vs shown) and update cadence (every 4 days vs every 3 weeks). PrimePop's advantage is device support (3 vs 1) and iOS requirement (15.6 vs 17.6). On price there is nothing between them.

Both are free to download. PrimePop sells 3 one-off in-app purchases. Quantum asks for nothing beyond the download.

Quantum ships an update every 4 days, PrimePop every 3 weeks. The most recent releases landed on October 4, 2026 and October 14, 2026 respectively.
