MelApp

Identify rapidly and accurately T, N, M parameters for melanoma staging, guiding you through the complex AJCC tables. Correct staging of melanoma is of fundamental importance for the correct treatment of patients suffering from this condition. In 2018, the eighth edition of the American Joint Committee on Cancer (AJCC) T-N-M classification came into effect to improve the prognostic stratification of melanoma. Calculating the stage of melanoma may not be easy. MelApp is a supporting app that helps you navigate quickly and accurately through the complex AJCC tables. By simply selecting items from a drop-down menu, set according to the criteria of the AJCC tables, MelApp also allows you to identify the three T-N-M parameters. By cross-referencing the three values thus obtained, the final result, parameter S, will help you determine the stage of the lesion as identified by the AJCC tables and suggest possible follow-up indications. MelApp is developed by Meeter Congressi in collaboration with Melanoma Unit - University of Campania "Luigi Vanvitelli", Prof. Giuseppe Argenziano, Dr. Elvira Moscarella, Dr. Gabriella Brancaccio and Dr. Teresa Russo.

Verdict
The clearest difference is update cadence: MelApp at monthly against EDF's every 7 months. EDF's advantage is iOS requirement (9.0 vs 11.0). On price, ads, in-app purchases and device support there is nothing between them.
