Verdict
The clearest difference is ads: Quazzl AI at none against Singing Lessons's shown. Quazzl AI also leads on update cadence (every 2 days vs fortnightly) and rating (4.7 vs 4.4). Singing Lessons's advantage is review sentiment (69% vs 60%). On price, ratings volume, in-app purchases and monetization model 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. Singing Lessons sells 6 in-app purchases, starting at $7.99 per 7 days and Quazzl AI sells 3 in-app purchases, starting at $6.00 per month. Whichever you choose, the download price is not the number that matters.
Quazzl AI holds the better App Store score, 4.7 against 4.4. Both are backed by a comparable volume of ratings — 194 and 95 respectively. Written reviews complicate that: 69% of Singing Lessons's written reviews are positive against 60% of Quazzl AI's, so the app with the better star average is not the one people write more warmly about.
Singing Lessons ships an update fortnightly, Quazzl AI every 2 days. Both last shipped on November 4, 2026.
