# InternetFM vs Sonic Detroit

The clearest difference is in-app purchases: Sonic Detroit at none against InternetFM's 1. Sonic Detroit also leads on rating (4.9 vs 4.7) and review sentiment (100% vs 89%). InternetFM's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 4 months). On price there is nothing between them.

Both are free to download. InternetFM sells 1 in-app purchase, starting at $5.99 per month. Sonic Detroit asks for nothing beyond the download.

Sonic Detroit holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Sonic Detroit has 91 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 89% of InternetFM's written reviews are positive against 100% of Sonic Detroit's.

InternetFM ships an update every 6 weeks, Sonic Detroit every 4 months. The most recent releases landed on November 2, 2026 and November 5, 2026 respectively.
