## What is PlasmidViewer Pro?

PlasmidViewer is a fast, native plasmid map viewer for iPhone, iPad and Mac. Open a sequence and see it the way you do in SnapGene or Benchling — as a circular map, a linear map, or an annotated sequence, with restriction sites, features, labels, ORFs and a ruler you can show or hide from a single View sidebar.

Built for molecular biologists, students and ehtusiasts, it reads the file formats you already use and renders them cleanly on every screen size, with no account to create and nothing to upload to a third-party server.

VIEW YOUR PLASMIDS • Circular, linear and annotated-sequence maps • A SnapGene-style "View" sidebar to show or hide enzymes, features, labels, ruler and ORFs • Pinch to zoom and pan anywhere on the map • Select features and restriction sites to inspect them

RESTRICTION-ENZYME ANALYSIS • Full restriction-enzyme analysis over a bundled REBASE-style catalog • Scope the map to an enzyme set, or show and hide individual enzymes • See cut positions directly on the circular and linear maps

OPEN THE FORMATS YOU ALREADY USE • SnapGene binary (.dna) • GenBank (.gb / .gbk) • FASTA (.fa / .fasta) • Raw sequences • Export back to .dna

YOUR LIBRARY, BACKED UP TO ICLOUD • Save plasmids to your personal library • Backup and sync through your own private iCloud (CloudKit) • Your sequences stay in your iCloud account — we never collect or see them

TRY IT FREE The bundled example plasmid is always free to open and explore, so you can see exactly how the maps and enzyme analysis work before subscribing.

SUBSCRIPTION Opening, importing, saving and iCloud backup require PlasmidViewer Pro, an auto-renewable subscription at $19.99/month. One subscription activates the app on one device at a time; you can move the active device any time from Manage Devices inside the app.

• Payment is charged to your Apple Account at confirmation of purchase. • The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. • Manage or cancel anytime in your Apple Account settings.
