# Tesdopi vs Khmer Knowledge

The clearest difference is in-app purchases: Khmer Knowledge at none against Tesdopi's 14. Khmer Knowledge also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Tesdopi's advantage is update cadence (every 3 weeks vs every 3 months). On price and device support there is nothing between them.

Both are free to download. Tesdopi sells 14 one-off in-app purchases. Khmer Knowledge asks for nothing beyond the download.

Tesdopi ships an update every 3 weeks, Khmer Knowledge every 3 months. The most recent releases landed on September 16, 2026 and September 10, 2026 respectively.
