Wind Correction
Read full descriptionHide full description
In athletics, wind conditions are a crucial factor for every athlete. Wind Correction is the first app that lets you accurately calculate what your time or measurement would have been under any desired wind conditions. Wondering how your performance might change with a neutral wind? Or curious to see your potential with a more favorable breeze? Simply select your event, input your recorded result along with the wind conditions you experienced, and choose the wind value you want to test. Wind Correction will do the rest! The app’s algorithm is based on the studies and research of M. Moinat, O. Fabius, and K.S. Emanuel. Their findings were published in 2018 in the article, Data-Driven Quantification of the Effect of Wind on Athletics Performance.
Hurdler Analysis

Hurdle Analyzer is an AI-powered technique analysis app for sprint hurdlers and their coaches. Using Apple's Vision framework, it detects human body pose frame-by-frame from a standard iPhone video, identifying key joint angles at the peak of each hurdle clearance. Each session produces a per-hurdle scorecard covering lead leg extension, trail leg mechanics, torso position, and flight time, with real-world distance measurements and cross-hurdle consistency tracking built in. A full education library covers technique guides, training drills, and biomechanics lessons across 100m/110m, 300m, and 400m hurdles. Athlete profiles track progress over time with trend charts for every key metric. Everything runs on-device — no internet connection required. For coaches: Hurdle Analyzer brings frame-by-frame biomechanical analysis to every practice session. Import a side-on clip of 1–3 hurdles, and the app instantly breaks down each clearance individually — scoring lead knee extension, trail leg fold, torso lean, and flight time on a 0–100 scale per hurdle. Rather than averaging technique across a full race, you get a precise read on exactly which hurdle broke down and why, with a side-by-side comparison showing whether mechanics are improving or deteriorating across the clip. Takeoff distance, landing distance, and clearance margin above the bar are measured automatically when athlete height is entered, turning subjective coaching observations into concrete numbers you can track session to session. For athletes: Stop guessing what's going wrong at the barrier. Hurdle Analyzer uses the same AI pose detection technology used in professional sports analysis, running entirely on your iPhone or iPad — no subscription, no cloud upload, no waiting. Have someone film you going over a hurdle, import the clip, and within seconds you have a scored breakdown of your lead leg snap, trail leg fold, and forward lean at the moment you're over the bar. Every session is saved to your profile so you can see your lead knee angle improving over weeks of training, and every coaching tip is specific to what the camera actually saw — not generic advice.

Verdict
The clearest difference is device support: Wind Correction at 2 against Hurdler Analysis's —. Wind Correction also leads on iOS requirement (15.6 vs 17.6). On price and in-app purchases there is nothing between them.
