MobAppCreator

Pros: Affordable which could be the selling point for this app
Your app will be pushed onto both Apple Store and Google Play Store

Cons: Hidden costs. after your application is uploaded to the Apple Store and Google Play Store, any update afterwards you will get charged for revisions and security updates/builds.

Overall: Not entirely true about the one time payment

They were very responsive when it came to submitting the app to both Apple store and Google play store but they failed to tell you that any time there's a security update and a new build needs to submitted with the changes you will pay $$$ amount every time... So the lifetime is just for hosting your app and that does not mean you will not be charged ever time you need to push another build or another update.

I am looking at an alternative since they've only been responding after they get paid. That's not what the deal I purchased was... The updates and revision pushes should be automatically applied. they are not even providing the app file to possibly try to do that on my own. they hold your app hostage on their platform. Now my google developer account is subject to be deactivated because the updates have not been submitted and I am sure they do get these notices but wait until you contact them to send you a link to pay them $$$ to update the build and submit it on your behalf.

Buy at your own risk.
