Featherline

A thoughtful medication tracker

Featherline is a medication tracker built for people on long-term hormone therapy who want to keep their personal records private.

Build a personal medication schedule, daily or weekly. Get reminders at dose times, with quick actions to mark doses as taken, log them later, or note when you've taken something outside your plan.

Visualize your routine

Featherline shows how your dose timing flows across the day and week.
