Submitting multiple apps with trivial differences, or an app whose primary purpose is redirecting to another app/website rather than providing standalone value, is treated as spam regardless of how it was built.
Common with template-based app factories that publish dozens of near-identical apps differing only in icon and color scheme.
"Your app is one of a series of apps with a similar name, icon, or content, and appears to be spam, per Google Play's Spam policy."
Under the spam policy, submitting multiple apps that differ only trivially, or an app whose main purpose is redirecting to another app or website instead of offering standalone value, is treated as spam however it was made. App factories that publish dozens of near-identical apps differing only in icon and colour scheme are the typical case.
A store full of duplicates makes it harder for people to find good apps and for honest developers to be seen. Redirect-only apps add little for users and can be used to push traffic or evade other rules. By defining spam in terms of the value an app offers, Google can act against low-effort mass publishing without needing to prove bad intent.
Only if each offers meaningfully different value.
Apps that only redirect may be, depending on the value they add.
The two cover similar ground from different platforms' perspectives.
