Verdict
The clearest difference is rating: FireLine at 4.6 against I.Q.'s 2.9. FireLine also leads on ratings volume (531 vs 7) and review sentiment (38% vs 23%). I.Q.'s advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 3 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. I.Q. sells 4 one-off in-app purchases and FireLine sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
FireLine holds the better App Store score, 4.6 against 2.9. That said, the two scores are not equally well evidenced: FireLine has 531 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 23% of I.Q.'s written reviews are positive against 38% of FireLine's.
I.Q. ships an update every 2 weeks, FireLine every 3 weeks. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
