## What is Slidequill?

Slidequill is a private microscopy record workbench for students, educators, field naturalists, and home microscopy benches.

- Clearly separated field-number estimates and stage-micrometer calibration
- Viewing magnification, optical field, image scale, image span, and scale-bar calculations
- Searchable chronology with calibrated and estimated status
- Optional local images selected through Apple's system Photos picker
- Complete local PDF and CSV record export
- 80 distinct offline bench methods with search and category filters
