I've seen a lot of peoples launching and sharing app online, but i had never launched an app myself before.

For the background, recently i had to create a lot of invoices and i didn't want to pay for any products out there, so i build one for myself over few days.

I focused on a simple and straightforward product with a straightforward UI:

• A toolbar with actions (download pdf, discount etc.)
• A form file that represent the invoice

It worked fine for my case, but i thought of, before sharing a few important features should be added:

• Multiples currency
• Templates

Then, launched it on X/Twitter and done!

Eventually after a few days it generated $90 (7 customers) which was quite unexpected.

It was a nice experience, and so, i decided to make another app soon!
wish you all the best
