# WorldStock vs RuinRisk

The clearest difference is price: RuinRisk at Free against WorldStock's $2.99. RuinRisk also leads on review sentiment (80% vs 67%). WorldStock's advantage is rating (5.0 vs 4.0) and in-app purchases (none vs 1). On ratings volume, update cadence, ads and monetization model there is nothing between them.

RuinRisk is free to download; WorldStock costs $2.99 up front. RuinRisk sells 1 one-off in-app purchase. WorldStock asks for nothing beyond the download.

WorldStock holds the better App Store score, 5.0 against 4.0. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews complicate that: 67% of WorldStock's written reviews are positive against 80% of RuinRisk's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. Both last shipped on November 1, 2026.
