**Background**
For the upcoming iOS watchlist feature, we will need to track metrics within the feature to ensure it is a success. Some of this metrics include but are not limited to things like: number of visitors to the watchlist, duration of visit and components interacted with. This task basically encompasses putting together the correct instrumentations based on appropriate event triggers to gather such information.
**The task**
[ ] Instrumentation to answer the question: How often are people clicking items in All Articles vs Reading List tab in iOS app? Bonus points if we have distribution of events in all articles vs reading list tab. From T334215 - Work is in progress
[ ] Instrumentation to answer the question: What is the monthly average edit rate in Northern and Western Europe and North America (US and Canada)? - currently in code review
**Requirements**
Instrument our existing features to answer the questions in T334215. If it will take longer than 2-3 weeks to instrument, notify Rebecca so we can cut the scope as necessary. We want to start having data come in within 3 weeks at the latest.
