# Breadpad vs CoPac

The clearest difference is in-app purchases: CoPac at none against Breadpad's 3. CoPac also leads on update cadence (every 3 days vs fortnightly) and iOS requirement (15.1 vs 18.0). Breadpad's advantage is ads (none vs shown) and chart position (#198 vs unranked). On price there is nothing between them.

Both are free to download. Breadpad sells 3 in-app purchases, starting at $4.99 per month. CoPac asks for nothing beyond the download.

Breadpad ships an update fortnightly, CoPac every 3 days. The most recent releases landed on September 23, 2026 and September 17, 2026 respectively.
