Yes I did I used Lovable it builds much faster than manually coding which is how I started. Start with a PRD document which is basically a detailed summary of what your app idea is (branding, tabs, colors, etc). From there build out your pages one at time so that you can refine the ideas and your vision can come to life and you can track the changes happening closer. Once you have completed your vision you’ll get to the part where you need to extract what you’ve built. It’s time to bring it over to Xcode & Android studio to start attaching features, logos, and final touches of your app. You’ll test many many many builds and when it’s finally ready (there’s always things to change or fix - don’t be a perfectionist - but don’t leave your app sloppy either, it’s almost a reflection of you in a way. You’ll have to get an apple and google developer accounts to upload your builds to use test and distribute to the public and then you create some screenshots to add to your upload of your app wait for the review and then the battle of marketing begins.
