In the modern era, mobile phones and mobile apps have become an essential part of daily life. If you are looking to create an app, you will face many challenges. Mobile app design should be your priority because users don't want to use an app that has design flaws. Don't try to mirror other apps. You can just take some inspiration but copying their design is a big no. The most significant challenge you will face is your poor budget. If your budget is low and you are new to this, try to find some free apps without hiring a designer.

Of course, that's really important indeed, but I feel like it's necessary to think about the internal part of the business. For some reason, I was underestimating it, and I had problems with my finances. But when I decided to open high risk accounts, everything started getting better, and I should've thought about it earlier.

That's true, but I think it's something inevitable, so entrepreneurs have to be ready for it. There are many technologies that help them develop their businesses, like contactless payments and different gateways, so it's not the hardest part. But I know that it makes some business owners quit this field and switch to other spheres.
