First, pick the job, then the tool
Parents ask for the best pitching app as if there is one answer. There is not, because these tools do completely different jobs. Some measure speed, some measure the ball, some help a coach mark up video, and some use AI to analyze the body. The smart move is to decide what you actually want to learn, then choose within that category. Here are the four buckets.
1. Radar: how hard is he throwing?
If you just want reliable velocity, a dedicated radar tool is the simplest answer. Pocket Radar is the popular choice, with a basic handheld model around $299 and a Bluetooth model near $400 that pairs with an app for speed-on-video overlays.1 It does one thing and does it well. Just remember that velocity is a number to monitor, not a target to chase, especially with young arms.
2. Ball-flight data: what is the ball doing?
If you want spin rate, movement, and pitch-design data, you are looking at ball-flight systems like Rapsodo and Trackman. These are powerful and accurate, and they are also expensive, facility-level equipment, with Rapsodo's pitching units running into the thousands and Trackman quoted at the enterprise level.2 For the vast majority of youth families, this is more tool, and more cost, than the situation calls for.
3. Manual video: a coach's eye on tape
If you want to record a delivery and have a human mark it up, frame by frame, with lines and angles, manual video apps are the category. OnForm is the leading one for coaches doing remote lessons (it absorbed the popular Hudl Technique, which was discontinued in 2021), and V1 Baseball is a budget-friendly option around $40 a year.3 Note that the older favorites Coach's Eye and Hudl Technique are both shut down. The strength here is a coach's expertise. The limit is that it still depends on a human eye catching fast details.
4. AI mechanics: automated analysis from a phone
The newest category uses computer vision to analyze the body automatically from a normal phone video, no markers, no coach required to draw lines. This space is small. Mustard is the main consumer app doing automated AI mechanics feedback, and it is positioned mostly around performance and drills. CritchPitch sits in this category too, with a specific focus the others do not center: screening the movement patterns associated with arm stress and health, and tracking them over time.
This is the open lane in 2026. Almost every tool measures performance, speed, spin, or mechanics for velocity. Very few are built around protecting the arm. If your first question is 'is my kid's delivery safe,' that is a different job than 'how do I add velocity,' and most apps are not built for it.
So which should you choose?
| If you want to know... | Use this category | Examples |
|---|---|---|
| How hard he throws | Radar | Pocket Radar |
| Spin and ball movement | Ball-flight (facility) | Rapsodo, Trackman |
| A coach's read on video | Manual video | OnForm, V1 |
| If the mechanics are safe | AI mechanics screening | CritchPitch |
| Automated mechanics for velocity | AI mechanics | Mustard |
Most families do not need the expensive facility hardware. A radar tool plus an AI mechanics screen covers the two questions that matter most for a young pitcher: how hard is he throwing, and is the way he is doing it putting his arm at risk. If that second question is the one keeping you up, start by reading [how to tell if the mechanics are safe](/library/are-my-pitchers-mechanics-safe) and [screening a pitch for free](/try).
Education, not a medical diagnosis or treatment plan. If your pitcher has pain, consult a qualified sports-medicine professional.
