Timesaving necessary tool

Absolutely essential. Being able to take screenshots and captures with bezels helps us to provide review pics/video to our design team.Having a way to actually see the current dynamic type setting is way more helpful that it may seem. Being able to examine the user defaults values with a click, set locations, turn off wifi. It is truely the app that keeps on giving.

Screen recording is good

Got this for the screen recording feature. Had some initial trouble wrangling the output because the UI that appears when a video is saved is has black text on a black background, making it illegibile. I first opened the raw capture file by mistake (because you can accidentally drag it to a browser window before you save it) and was disappointed with the quality, but on my next try, the video produced by Saving the recording was much higher. Would love to see some more polish on this app, and maybe the ability to adjust the export compression level, including exporting with loss-less compression.

Developer Response
The compression options should not be available in version 5.0 from the preferences. Let us know if you still need more flexibility: https://github.com/AvdLee/RocketSimApp/issues

Must have tool

This is a great tool for any developer looking to get a little bit more out of the simulator app that accompanies Xcode. Personally, I love being able to record a gif on command, rather than right-click>save as gif on the simulator. I also love being able to take a screenshot(with bezels!!!) then overlay that screenshot to compare small changes!

Stop reading and download this tool - I use it every day and it keeps getting better. I save a lot of time compared to times past when I would waste energy fiddling to test features not included with the native app simulator.The annual subscription is the best bargain out there.

Fixed: - Magnifier fails when moving to another display (Thanks, S. Lee!) - Captured photos using Simulator Camera now contain metadata (Thanks, F. Byaruhanga) - Roadmap view now looks good in light mode (Thanks, D. Vlasov) - Custom Simulator names are now properly recorded (Thanks, M. Sabaris)
