# Cardu vs ISIC

The clearest difference is ads: ISIC at none against Cardu's shown. ISIC also leads on review sentiment (18% vs 0%) and ratings volume (98 vs 6). Cardu's advantage is monetization model (ad-supported vs free with in-app purchases). On price, rating, 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.

On the App Store both sit at effectively the same score — 4.3 for Cardu against 4.3 for ISIC. That said, the two scores are not equally well evidenced: ISIC has 98 ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 0% of Cardu's written reviews are positive against 18% of ISIC's.

Cardu ships an update every 2 months, ISIC monthly. The most recent releases landed on June 4, 2026 and September 25, 2026 respectively.
