IBD Classes
Read full descriptionHide full description
The PIBD classes app was developed to assist clinicians in the diagnosis of paediatric IBD most specifically in the cases of patients with IBD when trying to distinguish between ulcerative colitis, Crohn’s disease and IBDU. The user should then use this and other clinical information to complete as many of the 23 questions needed to then generate a suggested diagnosis. Once you reach a diagnosis, no further questions are offered eg if class 1 features are present leading to a diagnosis of Crohn’s disease the class 2 and 3 features will not appear.

Verdict
The clearest difference is update cadence: NNI365 at every 6 weeks against IBD Classes's every 43 months. IBD Classes's advantage is iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
