WhatTheStar is free, carries no advertising and asks for nothing. If it has been useful, you are welcome to put something in.
Buy me a coffeeWhat it changes
It keeps the project's small running costs covered and buys a little more of the evenings that go into it — new guides, better ephemerides, and the long work of making a sky map correct rather than merely convincing.
Nothing is gated behind it. There is no paid tier, no unlock, no ads to remove and no queue to jump.
Other ways to help
Free, and sometimes worth more. Tell someone who has always meant to learn the sky. Report a star drawn in the wrong place, a time that is an hour out, or a guide that explains what you already understood and skips what you did not. Errors in an astronomy app are hard to notice and easy to fix once noticed.
