Verdict
The clearest difference is review sentiment: JADOH at 98% against DuoCards's 63%. JADOH also leads on rating (5.0 vs 4.7). DuoCards's advantage is ratings volume (1.4K vs 1) and update cadence (monthly vs every 5 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. JADOH sells 3 in-app purchases, starting at $2.99 per month and DuoCards sells 10 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.
JADOH holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: DuoCards has 1.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 98% of JADOH's written reviews are positive against 63% of DuoCards's.
JADOH ships an update every 5 months, DuoCards monthly. The most recent releases landed on October 15, 2026 and October 27, 2026 respectively.
