# Cosyra vs PreGrade Ultra

The clearest difference is update cadence: PreGrade Ultra at daily against Cosyra's every 6 days. PreGrade Ultra also leads on rating (5.0 vs 4.7). Cosyra's advantage is ratings volume (13 vs 2) and iOS requirement (16.0 vs 26.4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Cosyra sells 6 in-app purchases, starting at $20.00 per month and PreGrade Ultra sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PreGrade Ultra holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Cosyra has 13 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.

Cosyra ships an update every 6 days, PreGrade Ultra daily. Both last shipped on October 25, 2026.
