GCP2Go for Apple Watch – User Guide

General Tips

  • Constants: Built-in and user entered constants are automatically synced from paired iPhone.
  • History: Optional history sync with paired iPhone can be activated in the Settings screen.
  • iPhone Sync: Syncing is performed in the background, so changes on the paired iPhone may not appear immediately on GCP2Go on Apple Watch.
  • Graphs: Axis and plot line color and plot line thickness are obtained from the corresponding settings for GraphCalcPro2Go on the paired iPhone. Graph scale can be changed by rotating the digital crown. y-axis scaling is default. Touch and hold on the graph to toggle scaling for y-axis, x-axis, and both. Drag on the graph to move the origin.
