# AIMusic vs Double+

The clearest difference is review sentiment: AIMusic at 81% against Double+'s 20%. AIMusic also leads on rating (4.7 vs 3.4) and ratings volume (49 vs 7). Double+'s advantage is in-app purchases (none vs 21) and update cadence (every 6 days vs fortnightly). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. AIMusic sells 21 one-off in-app purchases. Double+ asks for nothing beyond the download.

AIMusic holds the better App Store score, 4.7 against 3.4. That said, the two scores are not equally well evidenced: AIMusic has 49 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 81% of AIMusic's written reviews are positive against 20% of Double+'s.

AIMusic ships an update fortnightly, Double+ every 6 days. The most recent releases landed on September 23, 2026 and June 5, 2026 respectively.
