# Frontier vs Thread Mark

The clearest difference is ads: Frontier at none against Thread Mark's shown. Thread Mark's advantage is update cadence (fortnightly vs monthly) and device support (3 vs 1). On price and in-app purchases there is nothing between them.

Both are free to download. Frontier sells 6 in-app purchases, starting at $1.99 per 7 days and Thread Mark sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Frontier ships an update monthly, Thread Mark fortnightly. Both last shipped on October 31, 2026.
