# DuoCards vs TANGO TRAINING

The clearest difference is ratings volume: DuoCards at 1.4K against TANGO TRAINING's 2. DuoCards also leads on iOS requirement (13.0 vs 15.1). TANGO TRAINING's advantage is rating (5.0 vs 4.7) and update cadence (fortnightly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. DuoCards sells 10 in-app purchases, starting at $19.99 per month and TANGO TRAINING sells 10 in-app purchases, starting at $18.00 per month. Whichever you choose, the download price is not the number that matters.

TANGO TRAINING 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 2, so its average is the more settled of the two.

DuoCards ships an update monthly, TANGO TRAINING fortnightly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
