# Nemos vs Estratum

Nemos and Estratum 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. Nemos sells 10 in-app purchases, starting at $4.99 per 7 days and Estratum sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Nemos ships an update weekly, Estratum every 10 days. The most recent releases landed on November 7, 2026 and November 6, 2026 respectively.
