Quick answer
Right now, I would treat Hearth and Hamlet as a Steam/PC game. I would not trust random Android APK or iOS download pages.
Current Status
- Steam lists Windows and SteamOS/Linux requirements.
- IncrementalDB also tags the game as Windows, fixed price, and having a demo history.
- I did not find an official Android or iOS listing in the core sources.
- Avoid APK mirrors. This is exactly the kind of keyword where bad download pages can appear.
Why People Search Mobile
Idle and incremental games feel like they should work on a phone, so the search intent is natural. But search demand is not the same thing as an official mobile release. The page should say that plainly.
Best Portable Option
For portable play, check Steam Deck and SteamOS/Linux first. That is closer to the official platform information than an unverified mobile download.
