Verdict

The call

The clearest difference is price: Index at Free against Full Stack Interview's $0.90. Index also leads on update cadence (fortnightly vs every 6 weeks). Full Stack Interview's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.6). On review sentiment, ads and in-app purchases there is nothing between them.
