"Every App included, we have researched and used (the front runners more so, others not so extensively) with selection based on our findings and have included those we find useful; reliable; relatively straightforward to use; reasonable/good value for money; and/or that stand out in their category for some reason. Of the many AAC Specialists reviewing, listing and blogging about Apps we have most closely cross-checked with Jane Farrell's list here. Most, if not all, the Apps that we have included, Jane has given either 2/3 or 3/3 stars in her 1 - 3 star rating."
