Native SwiftUI app with minimal resource usage. Your data never leaves your Mac: no tracking, no telemetry, and no cloud sync.

Very useful. Sometimes when I connect my iPhone 16 pro max and my Samsung T9 SSD it only shows the slow speed for one of them like 480 so I need to verify using this app and make sure they both show 10 for the speed which is a fast USB 3 speed so if it’s not i just disconnect and reconnect. I use that especially with the great local backup program that backs up the iPhone to the mac called iMazing. It’s like Time Machine for the iPhone. it can do so much.
Developer Response
That is awesome to hear! Verifying the connection speed before running a heavy local backup is a great use case. I'm glad the app helps you catch slow cables quickly. Thank you so much for the kind words!
Great App!

This app is so simple to use, I love it. I would love to see an option to let it fallback to the icon when no power source is connected, rather than having text saying “Connected/Not Connected” as I’d love to see it only for wattage when connected.
Developer Response
Thank you so much for the kind words and the fantastic review! I'm really glad you're finding the app simple and useful. That's an excellent suggestion for the menu bar display. I completely agree, that would be a much cleaner and more elegant implementation. I have updated the logic in the most recent update that matches your request. Suggestions like this are what help make the app better for everyone!
Very Handy!

Do you have a bunch of USB-C power bricks lying around, and you’re not sure which ones will supply enough power to quick charge your MBP? This is the app. Sure, you can look in system information every time you plug something in, but this is faster.
Developer Response
Thank you for taking the time to share your experience! It's fantastic to hear that the app is helping you sort through your power adapters. Feedback like this is incredibly motivating. Please don't hesitate to reach out if you ever have a feature request!
Perfect!

This app is great, it does exactly what it says it’s going to, and does it really well. It sits in the menu bar and provides the info as soon as any USB is plugged in. Doesn’t get in the way, and love that no subscription is required. Totally worth it
Developer Response
I am so glad you appreciate the straightforward approach, my goal was to make a simple tool that does its job well and stays out of the way. Hearing that it's "Perfect!" is the best feedback I could ask for.And thank you for highlighting the no-subscription model. I believe in providing great value with a single purchase, thrilled you feel it was totally worth it. Thanks again for your support!
