# SBF Theorie vs Bootspruefung.de

Both are free to download. SBF Theorie sells 15 one-off in-app purchases. Bootspruefung.de asks for nothing beyond the download.

SBF Theorie ships an update every 6 weeks, Bootspruefung.de every 2 weeks. The most recent releases landed on October 17, 2026 and October 3, 2026 respectively.
