Which database user registration solutions for android and ios app

[werner111]

I'm building my first quiz app in android studio with Kotlin. I have the .xml file ready for the registration and login page, what are the best options to store login data?

• I want to make a commercial app.
• Because its my first app I search for a free (or low cost) solution.
• I have experience (course) in postgresql
• I want to store also gamedata (for answer and question analysis)
  
• I want also ios.

Is sqlite a good solution? Is this free or do I need to work/pay with/for an api? Is firebase a good solution? is the phone vertification of 0.06 high or dont I need this? Or are there better options?

Thxs.

SQLite is suitable for storing data locally on Android devices.
But I think you may have to develop back-end applications and store user registration data in the back-end database.
In this case, you can choose MS SQL Server, MySQL, or even various cloud DBs.

Thanks for your answer, I have a few questions.
I have only data analysis skills in postgresql. Is it diffecult to make a back end database for apps?
Is MySQL enough, or do I need to pay for an api or something else?
I have Python skills for data analysis, so MySQL is a good solution.

It is not difficult to make just a back-end database. But you need to develop your backend application which is maybe a web api in order for your apps(iOS & Android) to call.
If the size of the data you want to store in DB is medium, I think MySQL is sufficient.

I can use the mysql database from my website hosting. I think that's the easiest.
Thank you for your help!!

Okay. You're welcome.
Would you like to leave a five-star for my app available on Play Store if it is convenient for you? Thanks in advance.
Hope the quiz app you are building will be successful!
