iPhone-camera batting app
SwingDino vs b4-app
b4-app is the closest thing to us out there, iPhone camera only, no gadget to strap on a kid. They built a serious "personal batting lab" that floods you with pro stats (attack angle, bat path, an exact contact point) a single phone camera can't honestly measure, and they keep your kid's swing video in the cloud. We measure the few numbers a phone can actually earn, throw the video away on purpose, and make it fun enough that a 7-year-old (and a 70-year-old) wants another cut.
Cheapest way to find out? Free.
Get the app, set your phone on a stand off to the side, and take a cut. No radar gun, no facility membership, no five-figure invoice.
Competitor specs and prices are gathered from public sources as of 2026 and may change, check each brand for current details. SwingDino is a fun, repeatable progress tracker, not a lab-calibrated instrument.
