Tools on the app
There on tools on the desktop version like adding an oval, rectangle or square and also an arrow, that are not available in the app. If these options were available I would be able to use it in the field. Otherwise I have to go back to office to edit the files instead of being able to do that on the job.

There are multiple tools available for app development. But during the development process, it's going through many processes like analysis, UI/UX design, testing phase, deployment, and support. In this process testing is the most important part of your app development. There are a lot of tools available for mobile app testing. I have gone through many blogs and I found one blog that gives the best tools for testers with its features, price, benefits, and limitations. I hope this article will help you to test your mobile application.
