Verdict
The clearest difference is ads: Calculator at none against Cuspart's shown. Calculator also leads on update cadence (every 2 weeks vs every 4 months) and ratings volume (8 vs 1). Cuspart's advantage is rating (5.0 vs 4.6) and iOS requirement (16.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Cuspart sells 1 one-off in-app purchase and Calculator sells 2 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Cuspart holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Calculator has 8 ratings behind it against 1, so its average is the more settled of the two.
Cuspart ships an update every 4 months, Calculator every 2 weeks. Both last shipped on November 3, 2026.
