If you onboard people to committing to something where they don't need to remember later to do it — an automatic action — what happens is you onboard, you exit out of the app, and then the next day you don't need to remember. It'll just start to block the app and you'll remember: oh, I committed to this, now I'm in.
Auto-Scheduling a Session in Onboarding Eliminates the Remember-to-Use-It Failure Mode
Opal's biggest onboarding win was creating an automatic Mon-Fri 9-5 blocking session for the apps the user named as distractions. The user doesn't have to return to activate it — it just fires the next morning. This sidesteps the most common reason productivity apps churn in week one: the user forgets to engage. Default-on beats opt-in when the product goal is behavior change.
Initial MVP took around two to three months maybe… I use Cursor a lot, but I'm very specific which files to touch and don't let the AI just go rogue basically.
Ship the MVP in 2-3 months and keep the AI on a tight leash — specific files only
The first version shipped in two to three months by scoping tightly around a tracker plus a custom workout engine. AI coding tools accelerated the work, but only when pointed at specific files rather than allowed to roam — autonomy is what produces unmaintainable sprawl.
There's a play for whatever you're stuck on.
