Opal Alternatives
Opal is described as 'lets you organize just about anything — ideas, reports, lists, notes, projects, graphics — in the form of an outline. If you used Acta, you’ll love Opal'. There are seven alternatives to Opal for a variety of platforms, including Mac, Windows, iPhone, iPad and Android Tablet. The best alternative is Orgzly, which is both free and Open Source. Other great apps like Opal are OmniOutliner (Paid), Visual Outliner (Freemium), OutlineEdit (Free) and Deep Notes (Free).
