What's New in RipReader

1.6.4

July 14, 2026

• Compare your throws by tag. A shared filter now works across both History and the Spray Chart, so you can line up throws from the same disc, round, or session. • When a throw lands outside the frame, RipReader now tells you which side got clipped so you can adjust your aim, and it no longer flags well-centered misses as edge clips. • Clearer advance-ratio guidance that names your throw type and explains what the number means for your skill level. • Fixed a capture screen that could get stuck with no way out if a throw was detected late. • The compass calibration warning now reminds you to remove magnetic phone accessories, a common cause of interference.

User reviews

Works not bad!

I think you can use the tech disc on this app? I was getting exact numbers. Then I switched to a regular disc and it took sometime to get speeds.

Update: It still took a lot of tries for me. I throw an average around 63-65 mph on the Tech Disc and this app said I threw 68 mph. That would be nice but I don’t think it’s accurate.

I don’t know how it works but maybe the wide lens needs to be used. I’ll continue to update my review as this app updates and enhances. I really hope the accuracy and experience gets better!

Response from developer

Hi! I really appreciate the feedback! If you have a throw that you think was the incorrect speed, please press the "Report Issue" button on the throw details screen. That allows me to diagnose what happened and improve the app for everyone.

Garbage app

All this app does is say “waiting for placement” while simultaneously heating my phone to the approximate temperature of lava. Not one feature works.

Response from developer

Hi, I'm really sorry that you've had a rough experience so far. If you're willing to keep trying, I suspect the issue might be a compass permission not being granted. Please check this setting: Settings > Privacy & Security > Location Services > System Services (scroll all the way to the bottom) > Compass Calibration, check that it's set to ON. If you are still having issues feel free to email me support@sarulian.com. I respond quickly and will get you up and running.

Free Trial need testing

The app seems great, but there’s some finicky parts of the app that take a few throws to understand: audio prompts for throwing, data display only shows after session, heat defo bugs out the app. I tried it out in a noisy outside space and got caught in a loop. I suspect it was because I hit my 5 throw limit, but it might have been the heat as well. I get that you want to get the revenue, but I wasn’t really able to assess the app to know if it’s worth the 25$/year

Unable to estimate speed

That title is about all I hear out of this thing.

Does what it says it can do

Awesome app that works as intended. Had a few tech disc/ RipReader sessions and the speeds were lining up within 1mph approx and even the RPMs seemed to be on point. I have a feeling this app is going to be as useful as UDisc to most players who are looking to improve their form/ distance. Well done
