# IQ Test vs IDFX Practice Test

The clearest difference is rating: IQ Test at 4.6 against IDFX Practice Test's 1.0. IQ Test also leads on review sentiment (38% vs 0%) and update cadence (every 2 weeks vs every 5 months). IDFX Practice Test's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. IQ Test sells 5 in-app purchases, starting at $4.99 per 7 days and IDFX Practice Test sells 1 in-app purchase, starting at $7.00 per month. Whichever you choose, the download price is not the number that matters.

IQ Test holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: IQ Test has 1.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 38% of IQ Test's written reviews are positive against 0% of IDFX Practice Test's.
