# Omega Calculator vs Cuspart

The clearest difference is ads: Omega Calculator at none against Cuspart's shown. Omega Calculator also leads on ratings volume (44 vs 1) and update cadence (every 2 months vs every 4 months). Cuspart's advantage is rating (5.0 vs 4.7). On price, in-app purchases, monetization model and device support there is nothing between them.

Cuspart holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Omega Calculator has 44 ratings behind it against 1, so its average is the more settled of the two.
