Verdict

The call

The clearest difference is rating: Power Focus at 4.7 against Stella's 4.2. Power Focus also leads on ratings volume (457 vs 26). Stella's advantage is update cadence (every 3 weeks vs every 4 months) and review sentiment (77% vs 66%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Power Focus holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: Power Focus has 457 ratings behind it against 26, so its average is the more settled of the two. Written reviews complicate that: 66% of Power Focus's written reviews are positive against 77% of Stella's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Power Focus ships an update every 4 months, Stella every 3 weeks. The most recent releases landed on September 30, 2026 and September 29, 2026 respectively.
