About this app

# ODude Note: Private Notes, Health Records & AI Prompts

ODude Note is an offline notepad for everyday writing, private notes, personal health records, period tracking, and AI prompts. No account or sign-in is required. Your information is stored locally on your device.

## Private Notes, Your Way

**Multiple Private Vaults**
Create multiple keys, each opening a separate notebook. Entering a different key opens its associated notebook, which appears empty if no notes have been saved under it.

**Public & Private Notes**
Keep everyday notes, lists, reminders, drafts, and personal thoughts organized in separate notebooks.

**Color Labels & Instant Search**
Use color labels to organize notes and quickly search note titles and text.

**Home Screen Widgets**
Access quick notes from your home screen with a choice of themes.

**Import & Share**
Receive text from other apps and share public notes when you choose.

## AI Prompt Manager & Runner

Save, organize, and reuse prompts for ChatGPT, Claude, Gemini, and other AI tools.

- **Dynamic Placeholders:** Detect variables such as {{topic}} and [audience] in your prompts.
- **Run Wizard:** Fill in the required details and copy a completed, ready-to-use prompt in one tap.
- **Customizable Fields:** Support single-line text, multiline input, and dropdown choices.
- **Star Favorites:** Bookmark frequently used prompts for quick access.
- **Reuse with Ease:** Keep useful prompts organized instead of rewriting them every time.

ODude Note helps you prepare and manage prompts. Use your preferred AI service separately to submit prompts and receive responses.

## Personal Health Records

**Offline Health Records**
Record and organize personal health information, symptoms, measurements, and other details. Keep dated entries to review your personal history.

**Separate Health Sections**
Organize different types of health information independently, making it easier to find and manage your records.

**Period Tracking**
Record menstrual period dates, review previous cycles, and view estimated upcoming period dates based on your recorded history. Predictions are estimates and may differ from actual dates.

Great app and amazing developer support! The developer updated this app for the first time in 10 years, which accidentally broke my data. But after a quick email to support, they pushed another update and recovered everything perfectly. Highly recommend!

It is a fine app but you might want to add one more feature of back up. I like the idea of having infinite passcodes as every word typed leads you to a different space and unless one knows the word they won't be able to access it. But when I shifted from one device to another, there was no way to back up all my notes at once. I could only share one note at a time which makes it a tiresome process for many notes. If you can back up one passcode space at a time, it would save a lot of time.
