# YLMSportScience vs Spleeft

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.

Both are free to download. YLMSportScience sells 5 in-app purchases, starting at $1.99 per month and Spleeft sells 13 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

YLMSportScience holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: YLMSportScience has 19 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 70% of YLMSportScience's written reviews are positive against 38% of Spleeft's.

YLMSportScience ships an update every 5 months, Spleeft every 3 weeks. The most recent releases landed on September 21, 2026 and September 16, 2026 respectively.
