Verdict
The clearest difference is update cadence: X at every 3 weeks against FITLAB Strong's every 4 months. X also leads on rating (5.0 vs 4.7) and ratings volume (426 vs 69). FITLAB Strong's advantage is monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.
