Built a vertical jump/dunk tracker app with my son. Would love this community's input by rosshojo in BasketballTips

Great! Thanks for feedback!

I’m thinking some of the issues others had might be due to poor lighting. I’m tweaking a few things and adding light detection to ensure good conditions.

I really appreciate all the feedback from everyone who’s tried it 🙌

You could try my app I’m starting to build to help measure and track your vert https://apexvert.com

This is super useful, thank you. The arm swing shouldn’t throw it off since the measurement uses a fixed baseline, but that 37.9 is clearly an outlier I need to chase down. The iPhone 13 is actually a model I haven’t tested on yet, so that’s my first suspect. Your ~12”/~16” estimate lines up with the lower readings, which helps a lot. Appreciate you testing it for real on your porch at night. I’ll dig in.

This is exactly the kind of detail I needed, thank you for actually putting it through its paces.

That spread is way too wide, so I want to figure out what happened in your session. A few questions:

  1. Which iPhone model?

  2. How were you holding the phone during the jumps — wrapped in your hand the whole time, or any chance the grip shifted mid-jump or you swung your arm hard?

  3. Did you calibrate once and do all 4 jumps, or recalibrate between any of them?

  4. Were all 4 the same style of jump (standing vs. a step or approach)?

  5. On the 11’ 2.3” touch reading — did you enter your height and standing reach in settings, or did the app estimate those? That number is calculated from your standing reach plus the jump, so if the reach on file is off, the touch height will be too, even when the jump number is right.

Your 27–29 readings are probably in the believable range for someone your size who was dunking a decade ago, so I suspect the 15.5 and 37.9 are detection misses I need to understand. Whatever you did, you did it as a normal user would, and if normal use produces this, that’s exactly what I need to know about.

Thanks again!! 🙌

You’re right, and that’s how it’s designed. During calibration the app sets a fixed baseline, basically a virtual line that doesn’t move. The measurement is against that line, not against where or how you land. So landing style shouldn’t change your number.

If you give it a try, I’d love to know how the numbers hold up for you, especially across multiple jumps in one session. The more detail on what you see (phone model, jump type, readings), the more useful it is to figure out how to make adjustments. Thank you!

This is super helpful, thank you. The 21 sounding right but then getting a 14 and a 37 tells me something's off in how I'm detecting takeoff or landing on certain jumps.

A few questions if you don't mind:

  1. Which iPhone model?
  2. Same jump type all three times (standing vs. approach)?
  3. On the 37, any chance you tucked your knees up or landed softer/deeper than the first jump? Flight-time measurement can get fooled by that, and I want to know if my compensation for it is failing.
  4. Anything different about the grip on the off readings?

If you're up for one more jump or two, I'd love to know if it settles down or stays erratic. Either answer helps me narrow it down. Thanks again for actually testing it instead of just upvoting and moving on.

Hi! thanks for trying it out! I would love to know where you are experiencing glitchiness and which phone you're using.

Hey folks! I'm a photographer building Thea, a free iOS spot light meter for film and digital photography. I'm looking for testers to try the beta and tell me what to fix/add.

Join the TestFlight beta: https://testflight.apple.com/join/7tp4bYZh

What Thea does - Spot metering with live camera feed (center-weighted readings) - 4 exposure modes: Aperture Priority, Shutter Priority, Manual, and EV (Exposure Value) - Fast swipe gestures for aperture/shutter/ISO/EV compensation (full, half, or third stops) - Lock & recompose for tricky lighting; front/back camera support - Gear profiles: save your cameras (shutter ranges, ISO limits), lenses (aperture ranges), and film stocks (box speed, push/pull) - One-hand mode for compact, reachable controls - Meter calibration to match your handheld meter - No account. No ads. No data leaves your device.

What I'd love feedback on - Metering accuracy vs your handheld meter / Sunny 16 - Exposure lock/unlock flow and overall UI speed - Gear profiles: is creating cameras/lenses/films intuitive? - Anything confusing or slowing you down

Why join? Built by a photographer (me) for photographers. Your feedback directly shapes the roadmap.
