TriniDo — ToDo System

By Fabian Merkle

This app is only available on the App Store for iOS devices.


Is your mobile todo list not fast or powerful enough for you?

Enter TriniDo: a fast ToDo list designed be your trusted system. It is built for Getting Things Done (GTD).
TriniDo is crafted to be your complete tool for organizing your todos. Manage all the commitments you have with yourself and others.

Your head is for having ideas, not for holding them. TriniDo offers an intuitive keyboard driven workflow: Enter thoughts quickly. You will be guided to decide on all that requires clarification. Have all your actions only a few taps away.

TriniDo focuses on what we see as the essence of GTD: action, context and outcome.


3 step workflow: Add, Decide, Act

• ADD - Capture what is on your mind: Whenever you think of something you need to do type it into TriniDo. Then continue what you were doing.

• DECIDE - Go through all thoughts you captured. Decide 3 things for them: action, context, outcome.

1. ACTION: the first physical step you can take, e.g. "search flight to Rome", "buy eggs", "read GTD introduction"
2. CONTEXT: the location, situation or person you require for doing the action, e.g. "market", "online", "Bob"
3. OUTCOME: the desired ultimate result of the action, e.g. "organize birthday party", "visit Paris"

It is easy to switch between action, context and outcome. Just swipe left or right.

• ACT - Select a context like "market", “call”, “team meeting" or “dad”. This way you see everything you can do at that moment. Follow your intuition when choosing which action to mark off next. Since you do not need to rethink your tasks again each time you can be productive stress-free.


• ADD - Collect fast.
Immediately start typing and press enter to capture whatever is on your mind. Swipe up on any list to enter what is on your mind as “quick capture”.

• DECIDE - Guided clarification.
See what needs attention: Each action needs a context. Each outcome needs at least one next action.
Easily do a weekly review by going through the "all actions" list and the outcome screen.

• ACT - Pick the right action to do next.
Search and filter to see the most relevant tasks for you. Start the text with a space, to enter "quick select", then type the context to quickly change between them.

TriniDo is designed to work best if you use Getting Things Done – GTD (trademark David Allen Company). This popular self-management methodology enables you to achieve stress-free productivity. TriniDo lets you put those steps into practice.

TriniDo is free. Pro features to make the app even more powerful will be added soon.
