Canva

1. Learn it

• ▸Not for building your app — for everything that sits beside it when you launch.
• ▸You start from a template that's already the right size, then swap the words and colours for yours.
• ▸The sizes matter more than the art: a launch banner that's cropped wrong looks careless.
• ▸Keep one brand colour and one font pair and your scrappy assets still look like a set.

Cost: Free tier; paid for brand kits and premium assets.

Write the banner before you design it

MessyDev never signs you up, spends your money, or touches your accounts. You do that part.
