# Blower vs Heritage Units

The clearest difference is price: Heritage Units at Free against Blower's $1.99. Heritage Units also leads on update cadence (every 10 days vs every 9 months). Blower's advantage is in-app purchases (none vs 2) and ads (none vs shown). On review sentiment, device support and iOS requirement there is nothing between them.

Heritage Units is free to download; Blower costs $1.99 up front. Heritage Units sells 2 in-app purchases, starting at $0.99 per year. Blower asks for nothing beyond the download.

Blower holds the better App Store score, 4.5 against 4.1.

Written reviews complicate that: 53% of Blower's written reviews are positive against 58% of Heritage Units's, so the app with the better star average is not the one people write more warmly about.

Blower ships an update every 9 months, Heritage Units every 10 days. The most recent releases landed on November 13, 2026 and November 6, 2026 respectively.
