How to Build an App with Lovable in 2026

Complete guide to building your first app with Lovable AI.

Time to first app: 1-3 hours


Step 1: Sign Up

  1. Go to lovable.dev
  2. Sign up (free tier available)
  3. Create new project

Takes 2 minutes.

Start here: Lovable


Step 2: Describe Your App

Be specific. Good prompt:

"Build a task manager where users can:
- Add tasks with title and description
- Mark tasks complete/incomplete
- Delete tasks
- See all tasks in a list

Use a clean, modern UI with blue accents."

Bad prompt: "Build a task app"

More detail = better results.


Step 3: Let AI Build

Lovable generates:

  • React frontend
  • Backend API
  • Database schema
  • UI components

Takes 5-10 minutes.

Watch the AI work. It shows progress.


Step 4: Test Your App

Click "Preview" to see it running.

Test everything:

  • Add a task
  • Complete it
  • Delete it
  • Check if it works

Found issues? Fix in next step.


Step 5: Iterate

App not perfect? Tell Lovable:

"The delete button should be red, not blue"

or

"Add a filter to show only completed tasks"

AI updates the app. See changes in real-time.


Step 6: Add Features

Start simple. Add features one at a time:

"Add user authentication so each user sees only their tasks"

Then:

"Add due dates to tasks"

Build incrementally. Test each feature.


Step 7: Deploy

Lovable deploys with one click.

  1. Click "Deploy"
  2. Get your live URL
  3. Share with users

App is live. Done.


Common Beginner Mistakes

Mistake 1: Vague Prompts

Bad: "Make it better"
Good: "Change the button color to blue and increase font size"

Mistake 2: Too Many Features at Once

Build one feature at a time. Test. Then add more.

Mistake 3: Not Testing

Test every feature before adding the next one.


Example App Prompts

To-Do List:

"Build a todo list with tasks, completion status, and delete functionality. Clean UI."

Booking System:

"Build a booking system where users can book time slots. Show calendar view and manage bookings."

Expense Tracker:

"Build an expense tracker. Add expenses with amount, category, date. Show total by category."

When to Use Lovable

Tips for Success

2. Be specific
Describe exactly what you want.

3. Test frequently
Check each feature works before moving on.

4. Iterate
First version won't be perfect. Improve it.


Next Steps

After building first app:

  1. Show 5 friends
  2. Get feedback
  3. Iterate based on feedback
