Lovable expert to finish website + app

I developed my app fatlossapp.com using Lovable but repeatedly hit loop blockers- burning through credits, causing much frustration and stoppinf me in my tracks since I am getting nowhere and spending too much.

I need a Lovable prompt expert to
* Finalise the site with my tick list of errors and amends
* Implement SEO/keywords for google (my site is hosted on Vercel)
* Launch the site into actual app mode for app mobile use on Apple + Google play

I need the above performed using less than 100 credits on Lovable
