In recent years, the development of mobile applications has been evolving and becoming more and more frequent. This event is positive, since it plays an important role in facing and mitigating the multiple adversities that appear in the different existing sectors, such as business. On the other hand, it was detected that a little known problem that many companies in the pharmaceutical industry experience is poor inventory management, which causes countless consequences, generally of a negative nature. For this reason, in this work it was decided to make a mobile application prototype to face this problem. In this regard, the RUP methodology was used, along with various computer tools, in order to elaborate the prototype. Besides, as a data collection technique, surveys were made, which were subjected to expert judgment, in order to qualify the prototype. Likewise, very satisfactory results were obtained, concluding that the mobile application prototype that was developed complies with all the necessary conditions to mitigate the inventory management problems of pharmaceutical industry companies.
