# X vs FITLAB Strong

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 (445 vs 89). 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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

X holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: X has 445 ratings behind it against 89, so its average is the more settled of the two.
