# StretchLab vs ChillRx

The clearest difference is review sentiment: ChillRx at 100% against StretchLab's 48%. ChillRx also leads on rating (5.0 vs 4.8) and iOS requirement (14.0 vs 16.0). StretchLab's advantage is ads (none vs shown) and ratings volume (11K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

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