Verdict
The clearest difference is ads: InkDeck at none against Codalingo's shown. InkDeck also leads on update cadence (every 9 days vs every 4 months). Codalingo's advantage is rating (4.3 vs 4.0) and ratings volume (20 vs 1). On price, in-app purchases, 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. InkDeck sells 3 in-app purchases, starting at $2.99 per month and Codalingo sells 14 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Codalingo holds the better App Store score, 4.3 against 4.0. That said, the two scores are not equally well evidenced: Codalingo has 20 ratings behind it against 1, so its average is the more settled of the two.
InkDeck ships an update every 9 days, Codalingo every 4 months. The most recent releases landed on September 18, 2026 and September 2, 2026 respectively.
