# Saudade FM vs ISFM

The clearest difference is rating: ISFM at 5.0 against Saudade FM's 4.0. ISFM also leads on ads (none vs shown) and update cadence (every 2 months vs every 5 months). Saudade FM's advantage is review sentiment (100% vs 67%). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ISFM holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 6 and 3 respectively. Written reviews complicate that: 100% of Saudade FM's written reviews are positive against 67% of ISFM's, so the app with the better star average is not the one people write more warmly about.
