# Cardu vs R

The clearest difference is rating: R at 5.0 against Cardu's 4.3. R also leads on ads (none vs shown) and monetization model (free vs ad-supported). Cardu's advantage is ratings volume (6 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

R holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Cardu has 6 ratings behind it against 1, so its average is the more settled of the two.

Cardu ships an update every 2 months, R every 3 months. The most recent releases landed on June 4, 2026 and September 15, 2026 respectively.
