Very good performance/cost ratio
The app covers the needs of a congress/conference for a reasonable price and this is what our clients usually asks for. The backend interface is really user friendly and accessible to everyone. You can count on the support team if you need it ! Twoppy takes in consideration our remarks and try to improve their app functionalities which is really appreciated. I'm really happy with the tool and just hope that the app will be available offline as well in the future.
