# ACI ECOLINK vs Invozen

The clearest difference is monetization model: ACI ECOLINK at free against Invozen's freemium. ACI ECOLINK also leads on ratings volume (20 vs 1) and iOS requirement (15.0 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.9 for ACI ECOLINK against 5.0 for Invozen. That said, the two scores are not equally well evidenced: ACI ECOLINK has 20 ratings behind it against 1, so its average is the more settled of the two.
