# Tone generator vs PXE

The clearest difference is in-app purchases: PXE at none against Tone generator's 3. PXE also leads on ads (none vs shown) and update cadence (every 4 weeks vs every 5 months). Tone generator's advantage is ratings volume (152 vs 3) and rating (4.0 vs 3.7). On price and device support there is nothing between them.

Both are free to download. Tone generator sells 3 one-off in-app purchases. PXE asks for nothing beyond the download.

Tone generator holds the better App Store score, 4.0 against 3.7. That said, the two scores are not equally well evidenced: Tone generator has 152 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 67% of Tone generator's written reviews are positive against 50% of PXE's.

Tone generator ships an update every 5 months, PXE every 4 weeks. The most recent releases landed on October 19, 2026 and October 12, 2026 respectively.
