Objective: To validate an app of the mobile health technology type for the notification of drug-related incidents in a Mobile Emergency Care Service. Method: Heuristic validation study of an app devised for notifying drug incidents in a pre-hospital emergency care service. To operationalize the entire process, from elaboration to validation of the app, the Design Thinking methodology was used. Validation was carried out following Nielsen's 10 heuristics, in a computer science institute from Rio de Janeiro, based on the analysis by 12 evaluators, who issued individual evaluations and then, in group reports. These assessments were carried out from use cases shared during validation. The evaluators were able to use the app to send a supposed notification and rate it. Results: The evaluators agree that the app fulfills its role, requiring usability adjustments, which were duly carried out, following the demands set out in the report. Conclusion: Analysis of the application by the evaluators resulted in an improvement in the app's interface. Therefore, the infringement points presented were developed to define a possible satisfactory correction, according to the end users' reality.
