## What is SplitsTreeApp?

SplitsTree computes and visualizes phylogenetic trees and networks. This is the iPad and iPhone edition of the SplitsTree program that is widely used in evolutionary biology, with the same methods, the same workflow and the same documents as on the desktop.

Evolutionary data often does not fit a single tree. Recombination, hybridization, gene transfer and plain noise leave conflicting signals in the data, and a phylogenetic network shows them instead of hiding them. SplitsTree takes you from an alignment, a distance matrix or a set of trees to a tree or network, and lets you explore the result with your fingers.

FROM DATA TO TREES AND NETWORKS
• Reads aligned DNA, RNA and protein sequences, distance matrices, trees and splits in Nexus, FASTA, PHYLIP, Newick and other common formats
• Distances: Hamming, Jukes-Cantor, K2P, HKY85, GTR, LogDet, protein ML and more
• Trees: neighbor-joining, BioNJ and UPGMA
• Split networks: neighbor-net, split decomposition and parsimony splits, drawn as networks or outlines
• Haplotype networks: median joining and minimum spanning network
• From sets of trees: consensus trees, consensus networks, consensus outlines and super networks
• Rooted networks: cluster networks and hybridization networks
• Bootstrapping, the Phi test for recombination, delta scores, phylogenetic diversity and more

INTERACTIVE VIEWS
• Viewers for trees, split networks, rooted networks and tanglegrams
• Zoom, rotate and select with touch gestures
• Find taxa, and format labels and lines
• Export images and data through the share sheet

EVERY ANALYSIS IS A WORKFLOW
An analysis is a chain of data and algorithms that leads from the input to the final view. Change an option anywhere and everything that depends on it is recomputed. The workflow is saved with the document, so an analysis started on the iPad can be continued in SplitsTree on a Mac, Windows or Linux computer, and the other way round, without any conversion.

FILES
Documents are kept in the app's own folder, which is visible in the Files app, so they can be copied, renamed or moved to iCloud Drive. Files can be opened from Files, Mail and other apps. Five example datasets are included to get you started.

ONE PURCHASE, NO DATA COLLECTED
No subscription, no ads, no account. The app does not collect any data, and all computations run on your device.

Designed for iPad; also runs on iPhone.
