# TC vs Exam DA

The clearest difference is in-app purchases: TC at none against Exam DA's 1. Exam DA's advantage is review sentiment (100% vs 73%) and device support (3 vs 1). On price, update cadence, ads and monetization model there is nothing between them.

Both are free to download. Exam DA sells 1 one-off in-app purchase. TC asks for nothing beyond the download.

TC ships an update every 8 months, Exam DA every 10 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
