Verdict
The clearest difference is review sentiment: Pyramid at 81% against CardStack's 0%. Pyramid also leads on ratings volume (91 vs 2) and iOS requirement (15.6 vs 26.0). CardStack's advantage is rating (5.0 vs 4.4) and update cadence (every 2 weeks vs every 9 months). On price, ads, in-app purchases and monetization model 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.
CardStack holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Pyramid has 91 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of Pyramid's written reviews are positive against 0% of CardStack's, so the app with the better star average is not the one people write more warmly about.
Pyramid ships an update every 9 months, CardStack every 2 weeks. The most recent releases landed on September 21, 2026 and August 31, 2026 respectively.
