# Noisapp vs MP3 Converter

The clearest difference is price: MP3 Converter at Free against Noisapp's $1.99. MP3 Converter also leads on ratings volume (49K vs 2) and chart position (#131 vs unranked). Noisapp's advantage is in-app purchases (none vs 4) and ads (none vs shown). On update cadence and device support there is nothing between them.

MP3 Converter is free to download; Noisapp costs $1.99 up front. MP3 Converter sells 4 in-app purchases, starting at $3.49 per month. Noisapp asks for nothing beyond the download.

Noisapp holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MP3 Converter has 49K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 100% of Noisapp's written reviews are positive against 83% of MP3 Converter's.

Both ship on a similar rhythm, roughly every 5 weeks. The most recent releases landed on November 1, 2026 and November 12, 2026 respectively.
