run vs RUN!
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
run
This running app simplifies pace calculations by allowing users to input any two of time, pace, or distance to instantly determine the third. Its intuitive design mimics a standard calculator for effortless operation and simulation.
- Instant pace calculation
- Input any two of time, pace, distance
- Intuitive calculator-like interface
- Easy simulation by changing values
- Minimum input required

This app is a pace calculator for runners. Troublesome time conversion is unnecessary. Moreover, operation can be done very intuitively. It is supposed to be done with minimum input. This calculator instantly calculates the remaining one by specifying any two of three elements of time, pace, and distance. So it is very easy to simulate by changing the value. The upper half is the input & display part and the lower half is the numeric keypad, like the general calculator. If you want to recalculate when all three items of time, pace and distance are filled, change one of the values and then tap the element-icon you want to calculate. With this application, it is fun to run even more!

Run Smarter with 3D Motion + AI Transform your smartphone into a biomechanics lab. Capture your stride. Analyze your form. Improve with precision. ///Overview/// This app offers full-body 3D motion analysis, AI-based feedback, and even ground reaction force (GRF) estimation — all from a single video recorded on your phone. Whether you're jogging, running, or sprinting, gain deep insights into how you move, where you can improve, and how to train smarter. ///Core Features/// • 3D Running Form Analysis Track your trunk lean, joint angles, stride mechanics, and symmetry — frame by frame. • AI-Powered GRF Vector Estimation Estimate ground reaction force angles and magnitudes with no sensors required. Understand how force is transmitted through your body at foot strike and push-off. • Detailed Biomechanical Feedback Receive professional-grade feedback on: Posture & alignment Left–right symmetry Center of mass (CoM) stability Contact time and GRF angles Stride efficiency and propulsion • Scoring System & Insights Get personalized scores across four domains: Stability, Efficiency, Symmetry, and Mobility — all computed using evidence-based benchmarks. • Custom Exercise Recommendations Based on your biomechanics profile, the app suggests targeted drills to correct imbalances, improve propulsion, and boost running economy. • Progress Tracking Visualize improvements in joint angles, contact time, vertical oscillation, and more over time. ///How It Works/// Just set your phone on a stable surface and run. Our system captures and processes your movement using advanced pose tracking and physics-based modeling — including real-time GRF estimation. /// Who It’s For /// Runners who care about form, not just pace Coaches, therapists, and biomechanists Athletes aiming for injury-free performance gains Data-driven individuals seeking clarity in their training No Sensors. No Lab. Just Science.
