To access the Sportreact PLUS subscription, go to Settings-> all subscription plans. Alternatively the upgrade will be offered to you when you try to access a PLUS feature in the app via the "UPDATE SUBSCRIPTION" button.
The subscriptions to PLUS are distinguished by two parameters- duration and athlete count. All the subscriptions have a month to month or yearly option. The amount of athletes determines which tier subscription you will require:
Tier 1- allows up to 5 athletes
Tier 2- allows up to 20 athletes
Tier 3- allows up to 80 athletes
Tier 4- allows up to 120 athletes
More than 120 athletes-contact support for a custom quote on this.
