# Mossi vs Shelvo

Mossi and Shelvo are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Mossi sells 1 one-off in-app purchase and Shelvo sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Mossi ships an update every 5 days, Shelvo every 8 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
