Making an app isn’t as simple, so there are some things to be aware of like
1. Cost
Making an app is free but publishing the app and getting the required items and extra features will cost you some money. That is why many would opt for professional help to sort budget and planning but doing it DIY sounds fun too
But ask yourself
Do I need some form of web presence to build interest and demonstrate capabilities?

What would be the amount of money I would be willing to put toward this app idea, my seed investment?

What would be the amount of time I have available to put toward this app idea?

2. Hardware
For apps on android, its easier, about any old computer would do it. Provided it has a decent amount of RAM and storage.

3. Time
The average time to make an app would be 3 months. This includes design, testing & development. Making an app is a huge time investment.
to make an app you’ll need to learn how to code, use youtube or blogs
For android, AndroidHive is pretty good. If you’d like the best experience, there are paid courses.



But Personally, i'd still recommend seeking professional help like Ultranet . Because there are app marketing and app maintenance to worry about, but in the case for Ultranets they are more different in that their launching and test running are thorough using QA testing, furthermore they like to work closely to ensure the app miss your ideas and suit your budget and timeline.
