Verdict
The clearest difference is review sentiment: Diam Calc Lite at 83% against GemGuide Pricing's 40%. Diam Calc Lite also leads on monetization model (free vs subscription) and update cadence (every 2 weeks vs every 69 months). GemGuide Pricing's advantage is rating (3.3 vs 3.0) and ratings volume (6 vs 1). On price, ads, in-app purchases 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. Neither carries in-app purchases, so what you see is what you pay.
GemGuide Pricing holds the better App Store score, 3.3 against 3.0. That said, the two scores are not equally well evidenced: GemGuide Pricing has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Diam Calc Lite's written reviews are positive against 40% of GemGuide Pricing's, so the app with the better star average is not the one people write more warmly about.
Diam Calc Lite ships an update every 2 weeks, GemGuide Pricing every 69 months. Both last shipped on October 24, 2026.
