DopaLoop is an iOS habit tracker that starts with goals ("better sleep", "less overwhelm") and lets you attach habits to them. Miss a day: nothing resets. The goal stays visible as an anchor or Northstar. The idea is that patterns over time matter more than daily streaks.
Tech: SwiftUI + SwiftData, with Foundation Framework and CoreML, fully local, no backend, no account. Privacy wasn't just a marketing decision, really. I just didn't want anyone to fear for their data, including myself or my kids. Everything stays on-device.
14-day free trial to get some momentum and gain insights from the analytics. No ads, no data collection.
Source isn't public, but happy to answer questions about the SwiftUI/SwiftData architecture, the HealthKit integration, or the ADHD-specific design decisions.

Yet another habit tracker, but the research citations for each habit are actually useful.
The product doubles down on the Seinfeld "don't break the chain" idea with sensible, social-forward features: 30-day heatmaps, unique public share pages, streak counters, reminders and a one-time lifetime purchase option. The landing page sells the behavioral pitch well, but the field is crowded and the promised "giftable streak tokens" concept (in the title) isn't clearly explained on the page — useful for individuals, not a breakthrough.
