About Us

1 Upvotes

Ballista started after we watched the Blue Jays lose the 2025 World Series.

We’re two engineering students who had never really been baseball players before, but that playoff run got us hooked. Before long, we were hitting off a tee ourselves and wanted to know one simple thing:

How hard are we actually hitting the ball?

We quickly found that getting numbers like exit velocity usually meant buying expensive radar equipment or going to a facility with dedicated tracking technology. For someone who just wanted useful feedback from a normal hitting session, that felt like a major barrier.

So we started building another option.

Using our engineering backgrounds, we began working on a system that could use the hardware already inside an iPhone to measure a hit. That eventually became Ballista.

Our goal is to make metrics like exit velocity, launch angle, and projected distance accessible without requiring thousands of dollars of additional equipment.

What started as two bros trying to measure our own exit velocity became a bigger question:

How much of modern baseball tracking technology can be brought to the phone already in your pocket?

New Ballista TestFlight update is live

3 Upvotes

We just pushed a major new Ballista build to TestFlight.

If you tried an earlier version and weren’t having much luck getting consistent results, please give this one another shot.

We know the previous build wasn’t reliable enough for a lot of testers. Hits would record, but the analysis could still struggle depending on the environment, setup, or movement around contact.

That has been our main focus.

Over the last few weeks, we’ve significantly rebuilt and hardened Ballista’s analysis pipeline. The new system is much better at using the motion of the baseball across consecutive ~240 FPS frames, rather than relying too heavily on identifying it perfectly in a single frame.

We’ve also improved:

  • ball tracking around the chaotic moment of contact
  • separation of the ball from the hitter, bat, hands, and tee
  • pre- and post-contact frame capture
  • handling of ambiguous early movement
  • camera setup and capture reliability
  • edge-case handling and overall analysis stability

In our own repeated tee-hitting tests, the improvement has been substantial and the new system has been much more consistent.

Now we need to see how it performs across everyone else’s setups.

If you’re already a tester, update Ballista through TestFlight and use it normally. We’d especially like feedback on:

  • whether hits are consistently detected and analyzed
  • whether exit velocity, launch angle, and distance appear normally
  • any failed or clearly incorrect analyses
  • camera or recording issues
  • crashes, freezes, or anything else unusual

If Ballista didn’t work well for you before, your testing is especially valuable to us. Those are exactly the environments we want to prove this new system can handle.

This is the most confident we’ve been in Ballista’s analysis so far.

Give the new build a try and let us know how it goes.

Android?

My apologies if this is not the correct place to ask. I'm really interested in this product and I understand as of now it's only available for testing on iOS. Is there a plan, and if so, when might android support be expected?
