# Zero vs PACC

The clearest difference is in-app purchases: PACC at none against Zero's 10. PACC also leads on iOS requirement (13.0.0 vs 17.0). Zero's advantage is update cadence (every 2 weeks vs every 18 months) and chart position (#112 vs unranked). On price, ads and device support there is nothing between them.

Both are free to download. Zero sells 8 in-app purchases, starting at $9.99 per month. PACC asks for nothing beyond the download.

Zero ships an update every 2 weeks, PACC every 18 months. The most recent releases landed on November 8, 2026 and November 4, 2026 respectively.
