Verdict
The clearest difference is update cadence: Kulmo at every 3 days against Rost's every 24 months. Kulmo also leads on ratings volume (19 vs 1). Rost's advantage is monetization model (free vs freemium) and review sentiment (100% vs 80%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Rost sells 1 one-off in-app purchase and Kulmo sells 6 in-app purchases, starting at $1.99 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 Rost against 4.9 for Kulmo. That said, the two scores are not equally well evidenced: Kulmo has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews are what separate them: 100% of Rost's written reviews are positive against 80% of Kulmo's.
Rost ships an update every 24 months, Kulmo every 3 days. The most recent releases landed on November 4, 2026 and November 13, 2026 respectively.
