mEMA License Levels


We offer the most flexible pricing in the industry. We believe that you should only pay for what you need. If your study will run for six months, then why pay for a full-year subscription? If you don’t need geolocation, why pay for it? Our three license levels are designed so you can get exactly what you need and upgrade whenever you are ready.

mEMA is the only commercially available EMA system that grows in complexity as your research does. We have already built advanced features into the system that can be easily turned on whenever you are ready for them.
