# Cello Key vs Examen CVQ

The clearest difference is in-app purchases: Examen CVQ at none against Cello Key's 1. Examen CVQ also leads on ads (none vs shown) and update cadence (every 3 days vs every 6 months). Cello Key's advantage is iOS requirement (14.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. Cello Key sells 1 one-off in-app purchase. Examen CVQ asks for nothing beyond the download.

Cello Key ships an update every 6 months, Examen CVQ every 3 days. The most recent releases landed on November 3, 2026 and October 29, 2026 respectively.
