Unofficial Save the World web app
StormBook shows what each mission alert rewards and whether you still need it for your Collection Book. Use the web app to add rewards as tasks, run the mission, and mark items collected without juggling notes, spreadsheets, or separate trackers.
StormBook works in the browser. The Android app is available through Google Play if you prefer the native app.
StormBook is independent and unofficial. It is not affiliated with, endorsed by, or sponsored by Epic Games, Inc.
StormBook Web
The web app gives players a browser-based way to review daily mission alerts, inspect Collection Book status, add rewards to tasks, and manage local progress. Progress stays in the browser unless you export a backup, and backups are designed to work with the Android app too.
Open the web appThe public guides explain how mission alerts, Collection Book tracking, and tasks connect. They are written for players who want to understand the tracker before using it and for search engines reviewing whether the site provides useful original content.
Read the Mission Alerts guideThe Android app remains available for users who prefer native features, but the website is no longer only a download page. StormBook Web can be used directly from the site, while the app adds platform-specific convenience such as native notifications and purchase handling.
Compare task and reminder behaviorThe FAQ covers common questions about local progress, backups, X-Ray Tickets, V-Bucks display mode, reset timing, and unofficial status. The changelog documents visible updates so users can see that the project is maintained.
Read the FAQConnected workflow
Collection Book progress stays tied to the items you actually need, and completed tasks can feed back into that progress instead of leaving you to update a second tracker later.
Each alert shows the reward and tells you whether it is missing from your Collection Book or already collected, so you can decide quickly if the mission is worth your time.
Turn rewards into tasks in one tap. One-time rewards like Perk-Ups and repeatable rewards are both supported, with a completion flow that keeps progress organized instead of scattered.
Keep a local export of your Collection Book, tasks, themes, and notification settings when you want a backup you can restore later through Android's document picker.
How It Works
Open the daily Mission Alerts list and see the mission, power level, reward, and whether that reward is still missing from your Collection Book.
If you still need it, add it to Tasks in one tap. StormBook supports both one-time rewards and repeatable rewards without splitting them into separate tools.
After running the mission, finish the task and update the Collection Book from the same flow, so your tracker reflects what you actually collected.

Privacy-minded by design
StormBook does not ask for your Epic Games password and does not require Epic account credentials. Most progress data is stored locally on your device, with optional backup files created only when you choose to export them.
