ADHD Second Brain App | Focus Timer, Brain Dump & Timebox Planner | Offline HTML Download

ADHD Second Brain is an offline HTML productivity app for planning tasks, projects and focused work. It is designed for adults who prefer a calmer place to capture ideas, choose a next step and plan their day, including people with ADHD or executive function challenges, freelancers, students and creators. It is a digital download, not a PDF planner, spreadsheet, native mobile app or cloud service. No account or subscription is required.

WHAT IS INCLUDED
You receive the interactive ADHD Second Brain HTML file and a detailed User Guide PDF. There is also a Quick Start Guide inside the app. The app brings together a Brain Dump, tasks and projects, a Focus Timer with Pomodoro options, visual Timeboxing, an Energy Dashboard, Help Me Choose, a Distraction Parking Lot and a Weekly Reset. You can choose from eight visual themes, Dark Mode and a dyslexia-friendly font option. Backup and restore tools, plus JSON and CSV export options, are included.

HOW IT WORKS
After purchasing, download the files from Etsy and save the HTML file to your computer. Open it in a modern desktop browser, then add your tasks, routines, notes and plans. No traditional software installation is required on a laptop or desktop. Your information is normally stored locally in the browser or viewing environment you use. Export regular backups from Settings.

COMPATIBILITY — PLEASE READ BEFORE BUYING
A Windows or Mac desktop/laptop with a modern browser such as Chrome, Edge, Firefox or Safari gives the most reliable and full experience. The layout can display on smaller screens, but locally downloaded HTML files behave differently across devices and browsers.

On an iPhone or iPad you may need a compatible HTML viewer to open the file. File handling, local storage, downloads, imports and backups can vary on iOS and between viewer apps. Some sections may need scrolling or zooming; buttons or advanced features may not work as they do on a desktop. Full iPhone/iPad functionality is not guaranteed. If mobile use is essential, please contact me through Etsy before purchasing.

IMPORTANT LIMITATIONS AND SAVING YOUR DATA
The app works locally and does not require an internet connection after download. It has no cloud account or automatic synchronisation: information entered on one device will not automatically appear on another. Clearing browser data can remove saved information, so avoid private/incognito browsing, check that your work has saved before closing the app and export backups regularly. To move information between devices, export a current backup and import it on the other device where supported. Your information stays in the local device/browser environment unless you choose to export or share a backup. Device and browser behaviour may vary.

This product is a productivity and organisational tool. It does not provide medical advice, diagnosis, treatment, counselling or therapy. It is not a replacement for support from a qualified healthcare professional. If you are concerned about ADHD symptoms or your wellbeing, please seek advice from an appropriately qualified professional.
