# Membership App vs CupCalc

The clearest difference is rating: CupCalc at 5.0 against Membership App's 3.8. CupCalc also leads on update cadence (fortnightly vs every 6 weeks). Membership App's advantage is in-app purchases (none vs 2) and ratings volume (19 vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. CupCalc sells 2 in-app purchases, starting at $12.99 per year. Membership App asks for nothing beyond the download.

CupCalc holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Membership App has 19 ratings behind it against 1, so its average is the more settled of the two.

Membership App ships an update every 6 weeks, CupCalc fortnightly. Both last shipped on October 24, 2026.
