Stardew Valley fans just got a powerful new sidekick for their farms and friendships. Gunther’s Library, a fan-made companion app for Android, is designed to keep your entire playthrough organized—and players are already raving about it. Launched on October 3, 2025, the app has quickly surpassed 5,000 downloads on the Google Play Store.
Built by developer BlueCaret, Gunther’s Library focuses on simplifying the way you track progress across the valley. The free version works on devices running Android 12 or higher and includes a complete item database, step-by-step guidance for both the Community Center and Joja routes, detailed villager gift preferences, and tidy collection lists. If you want even more control over your goals, a one-time premium upgrade for $5.99 unlocks advanced tools like a perfection tracker, personal notes, an in-app calendar, to-do lists, and support for managing multiple farms.
The idea came from a familiar pain point: constantly juggling dozens of wiki tabs while trying to plan the next in-game day. After nearly two years of development, the result is a polished, fast, and thoughtfully organized app that feels tailor-made for min-maxers and casual players alike. Early community reactions have been enthusiastic, with comments like “I can’t play without this app anymore” and “I’m reinstalling Stardew Valley just because of this app.”
As for availability, the app is currently Android-only. An iOS version isn’t planned yet, as the developer doesn’t have the necessary hardware to publish on the App Store, but a future release isn’t off the table. Supporters can chip in to help make that happen through voluntary contributions.
If you’ve ever wished for a clean, mobile-friendly way to track items, optimize your bundle strategies, and plan your path to 100% perfection, Gunther’s Library brings everything together in one place. Try the free version to get your farm organized, and unlock premium if you want deeper planning tools without a subscription.
