Time blocking app
A calendar can protect the time. TodoTrail helps you decide what to do inside it, in an order you can actually follow.

Beyond the calendar block
A two-hour focus block can still disappear into setup, indecision, and task switching. TodoTrail turns that block into a short sequence of visible actions, so the first move is ready before the timer starts.
How it works
Decide what should be true when the block ends: a draft exists, feedback is sent, or the first version is reviewed.
Add only the steps that support that outcome. Put setup first, focused work in the middle, and a clean handoff at the end.
If the block ends early, leave the current note in place. The route shows where to resume without reconstructing the session.
Built for the real day
TodoTrail does not pretend every minute will go exactly as planned. It gives a focus block enough structure to start, continue, and recover.
Keep the actual start and end time in your calendar. Use the route for the actions that belong inside that window.
Opening files, collecting references, and preparing a meeting are real steps. Put them on the route instead of hiding them.
Choose the sequence before the session so each completed task leads naturally to the next.
A block can end without the route disappearing. Keep the current state and make an intentional decision about what moves.
A good fit for
Turn a protected writing, coding, or design block into a short sequence with a defined finish.
Put review, practice, and recall in order instead of jumping between materials.
Group related calls, forms, and follow-ups into one focused route.
Practical questions
TodoTrail currently focuses on the task route inside a work session. Use your existing calendar for fixed time boundaries and TodoTrail for the sequence of work.
Usually three to five clear steps are enough. If the route becomes a full backlog, the block has probably lost its focus.
Yes. Set the timebox in your timer or calendar, then use TodoTrail to define the actions and the stopping point for that session.
