Choose two day types
Try early and night, clinical and off, or any two days that really appear in your week.
Choose two different kinds of days. Set the times that matter. Keep the same three small steps around them for one week.
Day types, three-step routines, daily check-ins, and wake modes stay free.

The goal is not a streak. It is to learn whether the same small routine still fits when the clock changes.
Try early and night, clinical and off, or any two days that really appear in your week.
Add a wake, start, and wind-down time for each day type.
Choose three actions you can repeat without rebuilding the whole plan.
Open the day type, follow what fits, and leave what does not.
Use your second day type. Keep the steps, but use its own anchors.
Use Momentum and the daily check-ins to note what you did. No perfect score is required.
At the end of the week, keep the actions that made sense on both kinds of days.

This is the real three-step plan in Volyia 1.6. You choose the day type and the anchors. Volyia keeps the plan small and visible.
Plus is for people who want a longer view after trying the routine. It is not required for this challenge.
For eligible U.S. users, annual Plus is free for 14 days, then $29.99/year unless canceled. Local pricing and eligibility on the purchase screen are authoritative.
Install Volyia, choose two day types, and set three small steps. You do not need an account or a subscription to start.
