Where to Play PokeIdle: PC, iPhone, and Android in the Browser
Play Free means open the official site. This page does not host an installer, and it does not link a third-party APK.
Open these addresses
Pokeidle.net: https://pokeidle.net/ — desktop browser. The developer has said the phone layout is not the focus. Pokeidle.io: https://pokeidle.io/ — PC and phone, one account, and the phone layout is an app-like view of the same site. Poke Idle World: https://poke.idleworld.online/ — no install, phone works. Pokeidle.com: https://pokeidle.com/ — browser plus a manifest for a PWA.
On iPhone, open the site in Safari, use the share sheet, and tap Add to Home Screen. On Android, use Chrome's install prompt when the site offers one. Com is the site that publishes the manifest tags. The others may only give you a bookmark.
After the page loads, return to which game you opened and the first half hour. If a download button on a video asks for a file, close it and use the safety notes.

FAQ
Is there a PokeIdle app?
Not on the official sites. Pokeidle.com can be installed as a PWA from the browser. The others are plain sites.
Does it work on iPhone?
Pokeidle.io and Poke Idle World describe phone play in the same account as PC. Use Safari or Chrome and, if you want an icon, Add to Home Screen.
Why not an APK?
No official Android package is linked. A random APK would be someone else's build of a browser game.
