Verdict
The clearest difference is rating: QRControl at 4.7 against Tentacle Timebar's 4.3. QRControl also leads on ratings volume (114 vs 4) and update cadence (every 2 months vs every 6 months). Tentacle Timebar's advantage is device support (4 vs 2). On price, review sentiment, 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.
QRControl holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: QRControl has 114 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 67% of Tentacle Timebar's written reviews are positive against 60% of QRControl's, so the app with the better star average is not the one people write more warmly about.
Tentacle Timebar ships an update every 6 months, QRControl every 2 months. The most recent releases landed on September 17, 2026 and August 10, 2026 respectively.
