Track canceled subscriptions in your OCaml application

Many OCaml applications have a subscription model where users pay a monthly or yearly fee to use the application. These applications are called SaaS or Software as a Service application. In these applications, users are usually charged a monthly or yearly fee and can use the application for that period. In some cases, users are on a pay-as-you-go model set for each action they perform in the application.

In either of these cases, a common issue that the application usually faces is when a user cancels their subscription, also called churn. Therefore, an application's churn rate is a critical metric that can significantly affect the application's revenue and, consequently, the sustainability of the application.

Therefore, SaaS applications should actively monitor when users cancel their subscriptions, the reason for the cancellation, and the overall churn rate. This way, the application can always be aware of the performance of the application and take immediate action if needed. For example, in the case of a high churn rate, the application can take action to improve the user experience to reduce churn. Or, in the case of a high-value user canceling their subscription, the application owner can take action to retain the user.

LogSnag is a powerful, real-time event tracking tool that works seamlessly with any OCaml application and is an excellent solution for tracking subscription cancellations and churn rates. With LogSnag, you can set up event tracking for anything you want and track when users cancel their subscription in your OCaml application in real-time. You may also set up optional rules to notify you and your team when a user has canceled their subscription.

In addition, LogSnag allows you to track user journeys and create a timeline of events for each user. This way, you can always track the activity of a specific user, such as when they have canceled their subscription and any other activity they have done in your application.
