Keep intermittent fasting, measured weight and goal progress in one journal. Set your fasting timer, including a 16-hour fast for a 16:8 routine, and use your weight tracker to review changes. If weight loss is your goal, follow your own records without promises of results.

Track fasting, morning fasted weight and tags for free. FastCue Free includes calendar history and basic trends. With Pro, use record-based analysis and insights to compare weekly and monthly changes, recurring habits and patterns, plateaus and recovery. Set reminders to support your diet routine and find one thing to compare next.

Free tracking and basic progress

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 and progress displays based on times you set and the active fast’s current goal. Notification permission and device settings are required.
• Export and import readable, unencrypted JSON yourself. Import replaces current local data after confirmation.
