Anyone else having issues with SwingVision on older iPhones? iPhone 13 Pro keeps crashing

As the title says, I’m trying to use the SwingVision app with my iPhone 13 Pro mounted on a SwingStick during my sessions.

For the past 4–5 months, the app has crashed during pretty much every recording, usually anywhere from 2 seconds to around 40 seconds after starting.

Recently, I tried using my wife’s iPhone 17 Pro instead, and the recording worked flawlessly for the entire session. That makes me wonder whether this is related to the older hardware rather than my setup.

So my question is: **what’s the oldest iPhone people are currently using with SwingVision reliably, without crashes?**

I know SwingVision mentions **“iPhone 11 / SE (2020) or newer”** in a few places on its website, but is that still realistic in practice?

I’d especially like to hear from anyone using an iPhone 11, 12, 13, or 14. Which model are you using, and does recording work reliably for you?
