AI Built My SaaS, Then Made It a Mobile App in One Click

I gave myself one afternoon to build a real SaaS with AI, and the part that got me was the mobile app. One prompt built the full web app. One click turned it into a mobile app too. Then I deployed the whole thing live for free. Here's exactly how it went.

I described a lead tracker CRM in plain English, hit go, and about four minutes later I had a working web app. Database, login, a searchable leads table, edit and delete, and a dashboard. Then one click generated a companion mobile app. Then I deployed it live and got a real link you can open right now, running on the free tier.

The tool is Modelence. You describe the app in plain English and it builds the full stack (frontend, backend, database, auth) then hosts and deploys it for real. Your first app comes with a free build credit and the free entry tier runs at no cost, so you can test an idea before you spend anything. When you're ready to run it as a real product with your own domain, it's $20 a month.
