# TriadXP vs Reaction Lab

The clearest difference is rating: Reaction Lab at 5.0 against TriadXP's 4.7. TriadXP's advantage is update cadence (every 2 months vs every 7 months) and ratings volume (44 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. TriadXP sells 10 in-app purchases, starting at $39.00 per month and Reaction Lab sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Reaction Lab holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: TriadXP has 44 ratings behind it against 2, so its average is the more settled of the two.

TriadXP ships an update every 2 months, Reaction Lab every 7 months. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
