Cladewright: Tree Studio

Support

Cladewright is an offline iPhone and iPad tree-inspection workspace. No sign-in or subscription is required.

Import a tree

  1. Open Library and tap the plus button.
  2. Choose Open Tree File for a Newick or NEXUS document, Paste Tree Text for clipboard content, or Add Sample for a fresh worked project.
  3. After parsing succeeds, Cladewright selects the project and opens Tree.

Supported source details

Newick input may contain quoted labels, doubled quote escapes, nested bracket comments, internal support labels, and optional finite nonnegative branch lengths. NEXUS input supports a TREES block, an optional TRANSLATE table, and TREE or UTREE statements. Unsupported or malformed values produce an error instead of being silently replaced.

Work with the tree

Use the segmented controls to choose rectangular or radial layout and topology or branch-length scale. Ladderize reorders branches for readability. Collapse hides descendants below the selected support floor. Tap a visible node to inspect it, focus on its clade, or reroot at an internal branch.

Join trait metadata

Traits accepts CSV with the columns taxon,group,value,note,color. Quoted multiline fields, doubled quotes, UTF-8 BOMs and Windows line endings are supported. Malformed quoting, repeated or empty headers, inconsistent column counts and missing taxon labels are rejected. Taxon matching is case-insensitive and diacritic-insensitive, while the source label remains unchanged.

Export a review packet

Open Export to share an individual Newick, NEXUS, trait CSV, SVG, or PDF file. Share Complete Packet creates every available format and presents them together in the iOS share sheet.

Backups and device changes

Projects live in Cladewright's private app container. Before deleting the app or changing devices, export a complete packet for each project. The packet preserves portable tree and trait files and a PDF report; it is not a full app-state backup and does not restore display settings or the entire library automatically. Cladewright does not operate a cloud-sync service.

Method sources

Cladewright links to the Interactive Tree of Life annotation guide and the NEXUS file-format specification. These references describe formats and presentation; they do not validate a project's biological interpretation.

Report a problem

Email support@shadowfetch.com with the device model, iOS or iPadOS version, source format, screen involved, and steps that led to the issue. Do not attach confidential research data unless you are authorized to share it.

Saved-library errors

If a saved library cannot be read, Cladewright preserves the original file and blocks changes. Use Save preserved library copy to save the file for recovery. This preserves the file but does not repair damaged data. Failed writes restore the last saved library state and display an error.
