Only for iPhone

iPhone
Keep intermittent fasting and weight management in one record. Set your fasting timer, including a 16-hour fast for a 16:8 routine, and log measured weight to follow your progress. If weight loss is your goal, review changes in your own records without promises of results.
Track fasting, morning fasted weight, and tags for free. With FastCue Free, review goal progress and basic trends. With Pro, use your records to compare weekly and monthly change, recurring behavior context, plateaus and recovery, and one thing to compare next.
Free tracking and basic progress
• Choose a quick goal or set your own fasting duration and target end time.
• Review fasting history in a calendar and timeline.
• Enter measured morning fasted weight manually in kg or lb.
• See weight-goal progress, checkpoints, and basic weight trends.
• Add tags before, during, and after fasting to preserve recorded context.
• Use the fasting heatmap and iPhone Home Screen widgets.
• Explore a fixed Pro Insights sample kept separate from your personal records.
Pro Insights from your records
When enough comparable history is available, Pro can show weekly and longer-term change, context observed alongside tags, times, and weekdays, weight change, plateaus and recovery, and one thing to compare next week. Insights show only the differences and context supported by comparable personal records. They do not claim a cause or health effect, guarantee an outcome, or prescribe an optimal fasting method. When history is limited, FastCue shows the summaries and progress that the available records support.
Pro management tools
• Review uncategorized and similar tags with advanced tag management.
• Use start, goal-end, morning-weight, and other notifications based on times you set and the active fast’s current goal. Follow progress with Live Activities on supported devices. Notification permission and device settings are required.
• Export and import readable, unencrypted JSON yourself. Import replaces current local data after confirmation.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Insights now uses shorter labels and clearer charts, with next week’s experiment on the main screen. Weight charts make period swipes and pinned tooltips easier to use. Fixed record charts appearing late or being cut off.
