What's New in Plasmids X

2.0.1

October 6, 2026

PlasmidsX 2.0 is a complete rebuild of the app. • New circular and linear maps: restriction sites labelled with their positions, small features drawn inside the ring, and an overview strip to move around long maps • A new sequence view with both strands, translations, feature tracks and enzyme sites, and a tool bar for the actions you use most • Restriction analysis with the commercially available enzymes from REBASE, aware of Dam, Dcm and CpG methylation • Digest & Gel: see the fragments on a virtual agarose gel • A library with folders, tags and favorites; import GenBank, FASTA, SnapGene and ApE files • Saved versions of every plasmid, and a Home Screen widget • On iPhone, iPad and Mac, with keyboard shortcuts, pointer support, Dark Mode, Dynamic Type and VoiceOver • Available in English, German, Spanish, French, Italian, Japanese and Simplified Chinese New: PlasmidsX Pro, a monthly or yearly subscription for sequence editing, cloning (restriction and ligation, Gibson Assembly, Golden Gate, Gateway and PCR), alignment, BLAST, NCBI downloads, and GenBank and SnapGene export. Viewing, importing, annotating and analyzing stay free. Features you bought in PlasmidsX 1 stay unlocked (sequence editing and cloning are part of Pro) — restore them in Settings. Your plasmids from PlasmidsX 1 are imported into the new library the first time you open the app.

User reviews

Horrible

Doesn’t support .dna file and does no let you create a plasmid.

Response from developer

Thank you for your feedback. As of version 1.8.5, we support .dna files for importation. If you need any assistance with the app please reach out to plasmidsapp@gmail.com for support.

not what it seems

Unfortunately, GenBank format import works very poorly (strips a lot useful information), manual re-annotation and correction are a hassle. Awkward graphics and not a very user-friendly interface.

Great iPad alternative to SnapGene

Hey, thanks so much for developing a plasmid app for iPad, this is great. My one gripe is that I can’t open files stored in OneDrive, and I need to copy them to be located on my iPad itself. I’d happily pay for this feature as a premium option if it were to become available.

Response from developer

Thanks for using the app! I am glad that the app has been useful for you. Unfortunately, due to limited resources, I don’t have an immediate plan to add native cloud storage support to the app. You can however effortlessly import plasmids from many cloud storage apps that support iOS Files app integration. Plasmids X has access to the Files app interface for import/export operations.
