Tree Atlas compared with OTISS, TreeCanopy and KeyTREE

Side by side

Not verified means we could not confirm it on the company's own public pages. It does not mean the feature is missing. The small numbers link to the note, source and date for each cell.

When to pick someone else

Tree Atlas is not the right tool for every team.

• OTISS

  If your team is Android-only and already uses OTISS, or wants its BS 5837 Survey and Tree Survey apps together. Tree Atlas for Android is built and in testing, not on Google Play yet.

• KeyTREE

  If your team draws in AutoCAD. KeyTREE is an add-in that keeps the trees inside the drawing.

• TreeCanopy

  If you want a voice-first app where you dictate each tree, with crew seats free (its pricing page). Its Solo plan is £24.99 a month; the VAT basis is not stated.
