Flutter
FigmaScan. Track. Done.
CalFit is the mobile app we built to remove the one step that kills most calorie trackers: manual entry. A meal gets logged with a photo, not a search box.
The Problem
Every major calorie app is built around the same workflow: search a food database, guess the portion, adjust for how it was cooked, repeat for every meal, every day. That workflow is accurate in theory and abandoned in practice. Most people quit logging within the first two weeks, not because they lack discipline, but because the tool asks for more effort than the habit can sustain.
What We Built
CalFit is organized around a single core action: point the camera at a plate.
- AI Food Scan. A photo of a meal returns an identified dish, an estimated calorie count, and a full macro breakdown (protein, carbs, fat) in one step.
- Self-adjusting target. The daily calorie target is not fixed at onboarding. It recalculates from the user's actual weight trend over time, so the number stays honest even when metabolism or activity changes.
- Weight trend tracking. A running trend line smooths out normal day-to-day water-weight noise so the number a person sees actually reflects progress.
- Hydration and fasting. Water logging sits alongside 16:8, 18:6, and 24-hour fasting timers for the people combining fasting with tracking.
- Workout tracking. Logged workouts feed back into the day's calorie math instead of living in a separate app.
How It Works
CalFit is built in Flutter and Dart, shared across iOS and Android from one codebase. Meal photos are processed through an AI vision model trained to recognize dishes and estimate portion size well enough to return a usable calorie and macro figure without the user typing anything. The self-adjusting target logic treats the user's own weigh-ins as ground truth and corrects the daily calorie number against that trend rather than trusting a static formula indefinitely. Figma drove the visual system, kept warm and encouraging rather than clinical, down to a small in-app character that reacts to logged meals.
The Results
CalFit ships as a live iOS app with a free tier and a Calfit+ upgrade for unlimited scans. The bet it validates is narrow but important: once the logging step drops from a minute of typing to a two-second photo, people who would have quit tracking by day ten are still logging on day thirty.
