# Home Assistant vs MARSTEK

The clearest difference is ratings volume: Home Assistant at 4K against MARSTEK's 11. Home Assistant also leads on rating (4.7 vs 4.5). MARSTEK's advantage is review sentiment (72% vs 54%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Home Assistant holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Home Assistant has 4K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 54% of Home Assistant's written reviews are positive against 72% of MARSTEK's, so the app with the better star average is not the one people write more warmly about.

Home Assistant ships an update every 10 days, MARSTEK every 2 weeks. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
