# Headspace vs Power Analysis

The clearest difference is rating: Power Analysis at 5.0 against Headspace's 4.4. Headspace's advantage is review sentiment (71% vs 50%) and update cadence (every 2 months vs every 4 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Headspace costs $3.99 and Power Analysis $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Power Analysis holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 10 and 3 respectively. Written reviews complicate that: 71% of Headspace's written reviews are positive against 50% of Power Analysis's, so the app with the better star average is not the one people write more warmly about.

Headspace ships an update every 2 months, Power Analysis every 4 months. The most recent releases landed on October 18, 2026 and October 9, 2026 respectively.
