Verdict

The call

The clearest difference is rating: YLMSportScience at 4.5 against Spleeft's 1.0. YLMSportScience also leads on review sentiment (70% vs 38%) and ratings volume (19 vs 2). Spleeft's advantage is monetization model (freemium vs subscription) and update cadence (every 3 weeks vs every 5 months). On price, ads and in-app purchases there is nothing between them.
