Raw observations
Daily scale weight and logged sets never disappear behind the smoothed line.
Graph views, not gamification
Your logbook already contains the signal. Flexbound sketches it.
Charts exist to answer a training question: Is the weight trend moving? Is maintenance converging? Did volume jump? Is the lift progressing? No rings to close, streaks to protect, or scores without a decision attached.
This is the running Expo app. The ink observations, pencil trend, axis labels, and brass goal line all ship in Flexbound and render from stored records.
Chart rules
What stays visible when the line gets cleaner.
Decision trend
A pencil-blue trend reduces noise only for the decision the chart is meant to support.
Target or reference
Brass marks a declared goal, prescribed range, or current target—not a universal ideal.
Confidence and provenance
Measured maintenance shows confidence and links back to the complete food days and weight trend that produced it.
Questions the graphs answer
BodyweightIs the trend moving at the intended weekly pace?
MaintenanceWhat intake maintained this observed weight trend?
Training volumeDid hard-set exposure change faster than recovery can follow?
Estimated 1RMIs performance rising across comparable sets?
AdherenceWere enough days complete to trust the conclusion?
Goal progressWhat changed since the goal was written in the notebook?
Coming to iOS
A graph should change the next decision.
Flexbound keeps the observation, trend, reference, and explanation together on the same notebook page.
