Verdict

The call

The clearest difference is review sentiment: TDAS mobile at 100% against Home Assistant's 54%. Home Assistant's advantage is rating (4.7 vs 3.7) and update cadence (every 10 days vs every 2 months). On price, ads, in-app purchases and monetization model 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 3.7. That said, the two scores are not equally well evidenced: Home Assistant has 4K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 54% of Home Assistant's written reviews are positive against 100% of TDAS mobile'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, TDAS mobile every 2 months. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
