In my last post, I have introduced a simple 4-steps framework to organise your thinking of tracking your App. In this post, I want to share with you three Metrics that I found helpful for product teams to monitor App health status.
Now, let’s discuss the metrics..
1- Usage: This metric is to answer how many users use the App flows/features/events. The absolute number is beneficial to know, but comparing it to benchmarks such as the previous periods or certain targets gives context to the number if it is good or bad. i.e. in Spotify App example, one event that you want to follow is upgrade_to_premium (How many users with free account upgrade to paid account). how this number is compared to the targets, and previous periods.
Another benefit for monitoring this metric is to see if certain features are used as expected. The usage trend may shows to you if your App users think of the features as you do, or if they give more weight to other features different that yours.

2- Success rate: This metric is the percentage of users who achieved what they want from the App successfully, with no technical issues. i.e. what percentage of App users succeed to upgrade_to_premium with no technical issue. Our hope that this percentage is 100%, but you might be surprised that this usually not the case, and % of users get technical errors for some reason or another. You can track this metric by collecting success parameter with your tracked events.

3- Completion rate: This metric is to measure how smooth are the App flows. It’s the ratio of users who complete the flow compared to the ones who start it. This should tell us where do users drop the most from the flow. One trick to be able to track this is to have consistent naming convention when naming events where the event position in the flow is mentioned in the event name. i.e. any event that has _start on it, is an event that start a flow, and any event that has _end or _complete on it means that it is the last event that should fire in the flow.

Summary
In this post, I discussed 3 metrics that Product teams can use to monitor App health status. The first is usage trends, and it aims to tell you which features are popular and which are not.
The second metric is success rate that aims to tell you if the user get any error while trying to achieve tasks in your app or digital product.
The last metric that we discussed is the completion rate and this metric tells you how smooth is your flows, and if users drop from it or not.
