What the 90-Day Challenge actually does

The 90-Day Challenge is a sponsorship feature — a configurable challenge window from 30 to 180 days that turns a goal into a structured timeline. The free trackers stay free forever; the Challenge is the optional structured program on top, included with sponsorship.

When you set one up, you provide:

• Start date — today, or a future date to schedule ahead
• Current weight and goal weight
• Duration — 90 days by default, adjustable from 30 to 180

From your goal and duration, the app calculates your daily calorie target and deficit. The duration is fixed once the challenge starts. There is no adaptive timeline that stretches or compresses based on progress, no banking of surplus days, no multi-week phases. You pick a window and the Challenge holds you to it.

What you see day to day

At the top: Day X of Y, a progress bar, days remaining, and a projected end date calculated from your start.

Below that, a Challenge Timeline — one card per day showing food, walking, and weight data auto-aggregated from the respective trackers. You don't re-log anything; the Challenge pulls from whatever you recorded in the Calorie, Walking, and Weight trackers for that date. Days before today show history; today's card updates live as you log.

Mid-challenge changes

• Goal weight is editable while the challenge is active. Changing it recalculates the daily calorie and burn targets so the Challenge stays aligned with the new goal.
• Reactivation — a completed or cancelled challenge can be reactivated within 24 hours of ending. After that window, starting again means creating a new challenge.
• Scheduling ahead — set a future start date to queue up the next block before the current one wraps.

How to use the Challenge

Choose a duration that feels serious but believable — 60 to 90 days is often the sweet spot. Review weekly, not daily; the timeline cards are built for pattern spotting, not hour-by-hour reaction. If the goal weight needs to move, edit it inline and let the daily targets update, instead of running the math in your head.
