Cult Fit <> Feature Requests
After a month with Cult, I’ve discovered a love for swimming and fitness—transforming from inactive to actively pursuing health. This blog shares suggestions I believe will benefit both me and fellow Cult users.
#1 Timelapse Video for Weight Loss
Idea:
Leverage Cult’s face-recognition check-in/out system to create timelapse videos showcasing users’ weight loss through facial transformations over time—an inspiring testimonial of their fitness journey.
Feasibility:
This is technically possible. Here’s a github repo I’ve made with basic proof of concept code files:
https://github.com/aakritpatel/cultfit
This POC only handles image resizing, reframing and timelapse creation. Identifying whether a user lost weight or not through images will be trickier and that needs to be handled separately (discussed later)
Google photos already creates a timelapse of this type. When a single person’s photos have been identified over a period of time, the memories section of Google Photos creates a collection of pictures of that person showing their pictures over time. Here’s a reference video:
Execution:
Such a video, will be a very strong testimonial of Cult’s role in keeping users healthy.
- Roll out for centers with face-recognition check-in / check-out.
- Limit the feature to users with 150+ photos.
- Incorporate weight-loss goals during onboarding and prompt users to update health details regularly. Use this data to filter users eligible for the timelapse.
- Use the data to generate timelapse videos for users achieving their fitness goals.
This feature would be a powerful motivational tool and testimonial for Cult.
#2 Alternative to the Current No Show Policy
Idea:
Cult’s current no-show policy blocks users for two days and deducts a day of membership, potentially demotivating them. Instead, allow users to pay a penalty (e.g., lose additional membership days) to unblock themselves, with penalties increasing for repeated no-shows.
This is based on the ‘Don’t miss two consecutive days’ rule of habit building.
Design and User Flow:
Reference design:

- Add an Unblock button to the blocked screen with clear information about the penalty.
- On clicking ‘Unblock’, display detailed terms:
- Unblocking deducts X days but retains no-show count.
- Penalty increases with repeated no-shows.
- Allow seamless unblocking to maintain user morale and habit momentum.
User Surveys:

Analysis and Experimentation:
Here’s a comparison between old and new policy

Based on the above analysis, there is potential gain for both the users and Cult fit in executing this system
A final decision can only be made after experimentation is done. Here are the details for experimentation:
