# QROX vs GSA

The clearest difference is review sentiment: QROX at 68% against GSA's 6%. QROX also leads on update cadence (every 5 weeks vs every 6 months). GSA's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

QROX ships an update every 5 weeks, GSA every 6 months. The most recent releases landed on September 22, 2026 and August 13, 2026 respectively.
