Verdict
The clearest difference is rating: FastR at 4.4 against DTE PowerControl's 3.0. FastR also leads on ratings volume (290 vs 4). DTE PowerControl's advantage is in-app purchases (none vs 2) and review sentiment (68% vs 38%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. FastR sells 2 one-off in-app purchases. DTE PowerControl asks for nothing beyond the download.
FastR holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: FastR has 290 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 68% of DTE PowerControl's written reviews are positive against 38% of FastR's, so the app with the better star average is not the one people write more warmly about.
DTE PowerControl ships an update every 2 months, FastR every 5 months. The most recent releases landed on October 18, 2026 and October 15, 2026 respectively.
