# Bilingual Library vs Dzongkha Test

The clearest difference is in-app purchases: Dzongkha Test at none against Bilingual Library's 10. Dzongkha Test also leads on update cadence (every 3 months vs every 16 months) and device support (3 vs 1). On price and ads there is nothing between them.

Both are free to download. Bilingual Library sells 10 one-off in-app purchases. Dzongkha Test asks for nothing beyond the download.

Bilingual Library ships an update every 16 months, Dzongkha Test every 3 months. Both last shipped on November 6, 2026.
