In the customer-facing Mariana Tek apps, you can customize the app colors, the ads that show in the app, and up to 4 additional "Integration tabs".
The "Integration tabs" are spaces that can be used for just about anything. You have the option to either work with a partner or build your own custom integrations. You can follow the development guide here for technical requirements.
If you elect to build your custom integrations, Mariana Tek can make recommendations for development partners. Some recommended partner integrations with Mariana Tek today include Spivi (performance metrics) and Challenges (challenge tracking).
If interested, please contact our Integrations team.
