Verdict

The call

The clearest difference is rating: FitTrack+ at 5.0 against Stackr's 4.4. FitTrack+ also leads on review sentiment (100% vs 68%) and monetization model (free vs freemium). Stackr's advantage is ratings volume (215 vs 6) and chart position (#164 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.
