Fovcus Amsler Grid Tracker — the main tracking grid with Draw, Bend and Vortex tools

Mark exactly what you see — with your finger

Compare

See exactly what changed between any two sessions

Pick any two saved sessions and place them side by side. The score, date and marking pattern are shown together so changes that might be invisible in isolation become obvious at a glance — and shareable with your specialist.

Side-by-side view Score comparison Both eyes separately

History

A complete dated record of every eye check

Every session is saved with its date, score and a thumbnail of what you marked. Scroll back through months of checks at a glance, tap any entry to expand it, or delete anything you don't need.
