This app allows you to record the diseases you suffer from and the expenses for their diagnosis and treatment, which can be: medications, medical consultations, imaging studies, surgeries, dental procedures, treatments and cosmetic surgery, etc. It also allows you to record doctor's appointments.
For example, let's say you are 50 years old and you have an old dream, namely to straighten your teeth. For this, you will go to the orthodontist about 30-40 times and pay for them, you will have x-rays, you will have orthodontic appliances installed and possibly other expensive parts. You can record all expenses and appointments in the app and in the end, after 5 years, you will know how much you spent on this personal health project.
