# AIVELA vs O.P.C.

The clearest difference is rating: O.P.C. at 5.0 against AIVELA's 3.2. AIVELA's advantage is in-app purchases (none vs 2) and ratings volume (26 vs 2). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. O.P.C. sells 2 in-app purchases, starting at $9.99 per month. AIVELA asks for nothing beyond the download.

O.P.C. holds the better App Store score, 5.0 against 3.2. That said, the two scores are not equally well evidenced: AIVELA has 26 ratings behind it against 2, so its average is the more settled of the two.
