# iFour Core vs Mat

The clearest difference is ratings volume: iFour Core at 28 against Mat's 2. iFour Core also leads on update cadence (every 2 months vs every 4 months) and iOS requirement (11.0 vs 17.6). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. iFour Core sells 2 in-app purchases, starting at $5.99 per month and Mat sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for iFour Core against 5.0 for Mat. That said, the two scores are not equally well evidenced: iFour Core has 28 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

iFour Core ships an update every 2 months, Mat every 4 months. Both last shipped on October 24, 2026.
