I was working on building a chatbot on WhatsApp - to help people build better habits. The bot would suggest a program consisting of daily/ weekly micro-goals for the habit the user wants to build. The bot also messages you with reminders ( set by user) and check-ins to see if users have completed their micro-goals. Ran a beta test with 20 odd users , didn't see much uptake. So back to drawing board. Not sure if I got my set of beta users wrong ( most of them are busy couples with kids) or if it was just the product.
