Just. Press. Play. Collectively, the stations on InternetFM are the craft brewers of radio and the app is their taproom.

Verdict

The call

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.
