How would you record a rocket's tilt angle several times a second during its ascent?

Say I had something like an EasyTimer and set it to ignite the second stage only if the tilt angle was less than 10 degrees. I fly it and the second stage doesn't ignite. How would I find out if I was close to that 10 degrees and what the tilt angle actually was?

I was thinking of something like a tilt sensor feeding an OpenLog and continuously recording the tilt angle to an SD card. But there are probably other ways to accomplish the same thing too?

Wouldn't you just download the flight log from the EasyTimer post flight? I've still not flown mine myself but my expectation is that it logs the flight onboard?

I have done it and whenever you play back your flight it shows the rocket moving in all directions. You can play it back on any Android devices.
I also have realtime telemetry
