28-day habit calendar for a fitness app

“Stiff back at 40? 28 days, 10 minutes, one move a day.”

The same calendar mechanic moved out of education into fitness. Each cell is one exercise, which makes the programme feel finite and easy to start. The headline names the pain, not the product.

Why it works

• A finite plan beats an open-ended subscription: 28 days feels like a commitment the viewer can actually keep.
• Naming the pain ('stiff back at 40') targets an age group without saying 'for people over 40'.
• Ten minutes a day is small enough to remove the 'no time' objection before it forms.
• Seeing Day 28 on the creative lets the viewer picture finishing, which drives installs more than 'download now'.

How to adapt it

1. 1.Write the pain in the viewer's own words: pull phrases from reviews or comments.
2. 2.Keep each day to one move or one action; progress should be visible across rows.
3. 3.Make the rest days visible: honesty about effort makes the plan more believable.
