The two pages split by purpose: page one is the streak, 100 numbered days you mark off one at a time, and page two is the habit log, where you record specifics (which habit, which days, any notes) rather than just a checkmark. The streak page gives you the big, visible arc, day 34 of 100 looks and feels different from day 3. The habit log gives you the granular record, which specific days you actually showed up, useful when you're troubleshooting why a streak broke.
The goal field is blank on purpose: a tracker built around a specific goal type (fitness-specific icons or workout fields, say) would need a different version for every use case. This one stays generic, so the same two pages work for a career goal in January and a different habit in June.
This tracker fits someone who already knows their goal and wants a visible record of showing up daily. It assumes you've done the goal-setting already and just need the tracking mechanism. It's a weaker fit if you haven't defined the goal yet, or if you want built-in structure around what to do each day (workout plans, meal plans, specific exercises); this tracker only tracks that you did the thing, not what the thing was. It's also not built for multi-week planning with weekly reviews or reflection prompts. If you want that layer, our 12-Week Goal Planner adds weekly check-ins and KPI tracking on top of a similar streak concept.
Compared to other trackers in the shop, this one is the stripped-down, single-purpose version: two pages that work for any goal. Our 30/60/90 Day Challenge Template is built around three distinct phases with different goals per stage, suited to a goal that evolves in chunks. This one assumes the goal stays constant across the full 100 days, and the only thing that changes is whether you showed up.
One deliberate choice: 100 days, not 90 or 66, even though habit-formation research points to a range near that rather than one fixed number. 100 was picked as a round, motivating number, long enough to get past the point where most goals get abandoned (usually somewhere in the middle third), but short enough to see the finish line from day one.
