The DERS iOS app has been deprecated. New web based DERS is now available. http://www.ders-app.org for more info. The Developmental Environmental Rating Scale (DERS) measures the quality of learning environments offered in classrooms serving children between the ages of 2.5 and 12. It aligns environmental design and implementation with desired outcomes related to executive functions, literacy, and social-emotional development. The DERS consists of 60 research-based environmental attributes or observable behaviors (child and adult) aligned with five broad aspects of human development: initiation and concentration, inhibitory control, working memory, linguistic and cultural fluency, and social fluency and emotional flexibility. The assessment is administered in a 60-minute classroom observation, during which the assessor records the presence, magnitude, and/or frequency for each item. Schools can use the DERS internally to identify priorities for continuous improvement or externally as an assessment of environmental quality. The DERS was developed by researchers at the National Center for Montessori in the Public Sector.

Verdict
The clearest difference is rating: DERS at 5.0 against Mosyle School's 1.8. Mosyle School's advantage is ratings volume (92 vs 4) and update cadence (every 2 months vs every 5 months). On price, ads, in-app purchases and monetization model there is nothing between them.
