I like the solution from https://www.diskinternals.com/uneraser/ a lot, and I think you will find it interesting and working for you too. It allows to recover all the lost data fast and nicely. Good luck with it!

I think native development is a much better solution for most of the apps. But sometimes, you just need a simple app for a website, for example. And you need to deploy it fast on different platforms. This is where react native comes. I would recommend you to check out the service from https://www.intellectsoft.net/services/mobile-development for mobile development. I am sure that they will help you with all your needs...
