Verdict
The clearest difference is ratings volume: SLT at 3.3K against FITunLtd's 2. SLT also leads on update cadence (every 4 weeks vs every 3 months). FITunLtd's advantage is monetization model (free vs ad-supported). On price, rating, ads and in-app purchases there is nothing between them.

On the App Store both sit at effectively the same score — 5.0 for FITunLtd against 5.0 for SLT. That said, the two scores are not equally well evidenced: SLT has 3.3K ratings behind it against 2, so its average is the more settled of the two.
