Verdict

The call

The clearest difference is monetization model: Stretch Authority at free against StretchLab's free with in-app purchases. Stretch Authority also leads on update cadence (every 10 days vs every 3 weeks) and iOS requirement (14.0 vs 16.0). StretchLab's advantage is ratings volume (11K vs 7). On price, rating, review sentiment and ads there is nothing between them.
