What Angular Baseball is

Good swing coaching has mostly gone to families who can pay for weekly lessons and live near a good facility. Angular Baseball gives any hitter with an iPhone the kind of mechanical read a hitting coach gives, in plain English, and keeps every swing so you can see whether a fix held.

What it does

• Grades the swing. Film from the side and the app tracks 33 points on the body through the swing. It grades 13 checkpoints across setup, load, stride, contact and follow-through, and gives the swing a score out of 100.
• Says what to fix first. Each problem gets a plain-English explanation and a severity, so the hitter works on one thing at a time.
• Prescribes drills. Every problem comes with a drill from a library of 20, matched to what the swing showed.
• Tracks progress. Every report is saved, so a parent, player or coach can compare this month's swing with last month's.
• Works for coaches. A coach keeps a roster, adds their own notes on top of the grade, and can send a parent a report that opens without the app. How it works for coaches.

It measures the body and reports hand speed. Here's exactly how a swing is scored, and here's a real report, unedited.

Who it's for

Parents who want to know what their kid should work on, players from about 10 to 18 who want to see their swing get better, and coaches who want to give every hitter on a roster feedback between lessons. Baseball and softball, righty or lefty.

What it costs

Free to start: 2 analyses a day and 5 a week, with no card and no expiry. A free coach account gets 1 analysis per player per day, up to 20 a week. Pro is unlimited and costs $9.99 a month or $49.99 a year, the same price for players, parents and coaches.

What you need

An iPhone on iOS 17 or later, and a side view of the swing with the phone held upright at hip height. Clips can be up to 20 seconds, and the app finds the swing in them.

The name

The App Store name is Angular Baseball: Swing Coach, and the website is angularsports.com. The app is unrelated to the Angular web framework and to "Angular-Baseball", an open-source browser game on GitHub. It was once called SwingAI, which is also the name of a different company's product, WIN Reality's SwingAI.
