# Breadpad vs IDFA

The clearest difference is in-app purchases: IDFA at none against Breadpad's 3. IDFA also leads on update cadence (every 3 days vs fortnightly). Breadpad's advantage is ads (none vs shown) and chart position (#50 vs unranked). On price and iOS requirement there is nothing between them.

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

Breadpad ships an update fortnightly, IDFA every 3 days. The most recent releases landed on October 11, 2026 and September 30, 2026 respectively.
