This is a health-related quality of life questionnaire asking your views about how your disease condition and/or treatment is affecting your daily life. In the absence of a haematology specific patient-reported outcome (PRO) measure for use in both clinical practice as well as clinical research, the European Haematology Association - Scientific Working group for ‘Quality of Life and Symptoms’, as part of its remit embarked on development of a new PRO measure for such purpose.

Verdict
The clearest difference is in-app purchases: HM at none against VTE Calc's 1. VTE Calc's advantage is update cadence (every 2 days vs monthly) and iOS requirement (9.0 vs 12.4). On price, ads and device support there is nothing between them.
