Helix Genetics vs PlasmidViewer Pro

Helix is a focused reference and study tool for the genetic code — every codon, every amino acid, and a live transcription/translation playground in your pocket. Whether you are a biology student grinding for an exam, a med-school applicant brushing up on biochemistry, or a curious mind who just wants to understand how DNA becomes protein, Helix gives you the answer in one tap. KEY FEATURES • Full codon table — all 64 codons mapped to their amino acid, with start and stop calls • Amino acid reference — names, three-letter and one-letter codes, side-chain class, and structure • Transcribe & Translate — paste or type a DNA sequence and watch it become mRNA and protein in real time • Quiz mode — drill yourself on codon → amino acid, amino acid properties, and start/stop signals • Search any nucleotide triplet, three-letter code or one-letter code instantly • Clean, distraction-free design built for quick reference and longer study sessions • Fully offline — your sequences never leave your device DESIGNED FOR STUDY Helix stays out of your way. No accounts, no popups, no upsells. Open the app, find what you need, and get back to learning. PRIVACY No tracking. No accounts. No data collection. Sequences you paste stay on your device.

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.
