# ARMOR vs Seriport

The clearest difference is ads: ARMOR at none against Seriport's shown. ARMOR also leads on device support (3 vs 1). Seriport's advantage is update cadence (every 2 days vs every 2 weeks) and iOS requirement (16.0 vs 18.0). On price and in-app purchases there is nothing between them.

Both are free to download. ARMOR sells 3 in-app purchases, starting at $4.99 per month and Seriport sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ARMOR ships an update every 2 weeks, Seriport every 2 days. Both last shipped on October 31, 2026.
