# TREMBLE Studios vs 4D Fit

The clearest difference is ratings volume: TREMBLE Studios at 2.3K against 4D Fit's 1. 4D Fit's advantage is monetization model (free vs ad-supported) and iOS requirement (14.0 vs 16.0). On price, rating, review sentiment and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 5.0 for TREMBLE Studios against 5.0 for 4D Fit. That said, the two scores are not equally well evidenced: TREMBLE Studios has 2.3K ratings behind it against 1, so its average is the more settled of the two.
