# Baly4Docs vs My successful KROK

The clearest difference is in-app purchases: My successful KROK at none against Baly4Docs's 1. My successful KROK also leads on device support. Baly4Docs's advantage is update cadence (every 4 months vs every 15 months). On price and iOS requirement there is nothing between them.

Both are free to download. Baly4Docs sells 1 in-app purchase, starting at $9.99 per year. My successful KROK asks for nothing beyond the download.

Baly4Docs ships an update every 4 months, My successful KROK every 15 months. The most recent releases landed on September 6, 2026 and June 1, 2026 respectively.
