Verdict
The clearest difference is in-app purchases: Cardzilla at none against Rogervoice's 5. Cardzilla also leads on review sentiment (91% vs 67%) and iOS requirement (13.0 vs 16.0). Rogervoice's advantage is ratings volume (1.8K vs 76) and rating (4.8 vs 4.6). On price, ads, 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. Rogervoice sells 5 in-app purchases, starting at $2.99 per month. Cardzilla asks for nothing beyond the download.
Rogervoice holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Rogervoice has 1.8K ratings behind it against 76, so its average is the more settled of the two. Written reviews complicate that: 91% of Cardzilla's written reviews are positive against 67% of Rogervoice's, so the app with the better star average is not the one people write more warmly about.
Cardzilla ships an update every 4 weeks, Rogervoice every 11 days. The most recent releases landed on October 15, 2026 and October 21, 2026 respectively.
