# Headspace vs KTrunk

The clearest difference is price: KTrunk at Free against Headspace's $3.99. KTrunk also leads on rating (5.0 vs 4.4). Headspace's advantage is in-app purchases (none vs 3) and review sentiment (71% vs 50%). On update cadence, ads and device support there is nothing between them.

KTrunk is free to download; Headspace costs $3.99 up front. KTrunk sells 3 one-off in-app purchases. Headspace asks for nothing beyond the download.

KTrunk holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Headspace has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 71% of Headspace's written reviews are positive against 50% of KTrunk'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, KTrunk monthly. The most recent releases landed on September 22, 2026 and June 4, 2026 respectively.
