# A2Z Groups vs aContacts

The clearest difference is rating: A2Z Groups at 4.6 against aContacts's 4.0. A2Z Groups also leads on review sentiment (82% vs 54%) and ratings volume (3.9K vs 45). aContacts's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (13.0 vs 16.0).

Both are free to download. A2Z Groups sells 4 in-app purchases, starting at $0.99 per year and aContacts sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

A2Z Groups holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: A2Z Groups has 3.9K ratings behind it against 45, so its average is the more settled of the two.
