Questions before you choose
Can Base44 publish mobile apps?
Yes. Base44 documents IPA and AAB generation on Builder or higher. Its mobile package runs the published web app in a secure web view; it is not a generated React Native app.
Is Newly free?
Newly has no free plan. Your organization needs paid credit or credit granted by Newly before the agent can work.
Does source export mean every feature is ready?
No. Both platforms offer code export. Device features, backend services, payments and store submission still need the appropriate setup and testing.
