Verdict
The clearest difference is in-app purchases: The Oscillator at none against MultiTone Generator's 7. The Oscillator also leads on iOS requirement (9.0 vs 15.5). MultiTone Generator's advantage is update cadence (monthly vs every 5 months) and rating (4.6 vs 4.3). On price, review sentiment, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. MultiTone Generator sells 7 in-app purchases, starting at $1.49 per month. The Oscillator asks for nothing beyond the download.
MultiTone Generator holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: MultiTone Generator has 355 ratings behind it against 58, so its average is the more settled of the two. Written reviews complicate that: 85% of The Oscillator's written reviews are positive against 80% of MultiTone Generator's, so the app with the better star average is not the one people write more warmly about.
The Oscillator ships an update every 5 months, MultiTone Generator monthly. The most recent releases landed on October 13, 2026 and October 7, 2026 respectively.
