# Quantum Frequency vs Signals Generator

The clearest difference is rating: Signals Generator at 4.7 against Quantum Frequency's 4.1. Signals Generator also leads on ratings volume (29 vs 7) and device support (4 vs 2). Quantum Frequency's advantage is in-app purchases (none vs 14) and update cadence (every 7 months vs every 33 months). On price and ads there is nothing between them.

Both are free to download. Signals Generator sells 14 one-off in-app purchases. Quantum Frequency asks for nothing beyond the download.

Signals Generator holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 7 and 29 respectively. Written reviews complicate that: 80% of Quantum Frequency's written reviews are positive against 67% of Signals Generator's, so the app with the better star average is not the one people write more warmly about.

Quantum Frequency ships an update every 7 months, Signals Generator every 33 months. The most recent releases landed on September 7, 2026 and September 20, 2026 respectively.
