# DOTRIX! vs ONO

Both are free to download. DOTRIX! sells 1 one-off in-app purchase and ONO sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

DOTRIX! ships an update every 4 days, ONO every 2 months. The most recent releases landed on June 1, 2026 and September 10, 2026 respectively.
