# Thermal Vision vs Question

The clearest difference is review sentiment: Question at 100% against Thermal Vision's 0%. Question also leads on rating (4.5 vs 4.1). Thermal Vision's advantage is ads (none vs shown) and update cadence (daily vs every 5 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. Thermal Vision sells 3 in-app purchases, starting at $6.99 per 7 days and Question sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Question holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 53 and 40 respectively. Written reviews point the same way: 0% of Thermal Vision's written reviews are positive against 100% of Question's.

Thermal Vision ships an update daily, Question every 5 months. Both last shipped on November 4, 2026.
