Lift 1.5 is our biggest new release since launch and reminders are the biggest new feature. Download now.
We often explain our behavior design philosophy using the B=MAT modelfrom BJ Fogg at Stanford. In the model, there are three parts to supporting a new behavior: increasing Motivation, increasing Ability (or decreasing difficulty), and Triggering the thought to do the behavior.
In the launch version of Lift, all we did was provide a boost to motivation through data visualization and community props. Then we added discussions, which underpins the community support that increases your ability by making you smarter.
We had a bit of debate about this feature, which is why it came after launch. On the one hand, it’s always been high on people’s wish list. But from my perspective, I’m terrified of building an app that people perceive as nagging. We’re about positive support and have been trying to avoid anything that felt like guilting, shaming, or nagging (even though many of our users think this would work on them).
Normally, you set a reminder as a repeating alarm (for example in your calendar) and then you hear that alarm day after day regardless of whether it is effective. A lot of people ignore the alarm. If we built our reminder feature this way, we’d be essentially creating the habit of ignoring your habits.
Algorithmically, we’re using an exponential back off. If you miss one reminder, the next one comes two days later. If you miss that reminder, the next comes four days later. The pattern repeats with 8 days, 16 days, and 32 days.
