Premium: Cost = CHF 4.00/user. Offering many more customizable features, this version allows developers to recover the investment costs of the project launch phase.

Business: Specially developed for companies. Its main feature consists in the following possibility: the Covid19-positive employee has the possibility of sending the app's log file to the employer. The latter, via our separately purchasable app version, can view the contacts he had with other employees during the previous few weeks and, if necessary, order quarantine.
App: CHF 10.00/user, discounts for more than 20 employees. Application to read log files of the infected employee: CHF 200.00 (purchase is not mandatory).

Education: Version for compulsory and post-compulsory schools.
Kindergartens and primary schools need a "key chain" that every child must wear. The teacher will have the application that will warn him/her if it detects too close contacts between pupils.
