After a soft-launch of two months, more than 50% of users have already installed the new mobile app. During this period, the app has received very positive feedback and is described as  “a very big progress”. The old app will be permanently phased out in the coming months.
In addition, the new app will also become an important instrument to attract new customers through a 'free trial' option. In this way, the mobile app becomes a full-fledged marketing channel and conversion tool for Teamleader.

In the meantime, Teamleader is working independently on the further evolution of the new app, which was made possible by very good technical cooperation between the teams.
