Verdict
The clearest difference is update cadence: Idioms at every 3 days against Tavi's weekly. Tavi's advantage is ratings volume (6 vs 1). On price, rating, review sentiment and ads 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. Idioms sells 3 in-app purchases, starting at $1.99 per month and Tavi sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Idioms against 5.0 for Tavi. That said, the two scores are not equally well evidenced: Tavi has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Idioms ships an update every 3 days, Tavi weekly. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
