Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
