A north star metric is the single measure that best captures the value your app delivers to users and predicts long-term growth, such as weekly active listeners for a music app or completed workouts for a fitness app. Choose a metric tied to real user value, that the team can influence, and that leads to revenue. Support it with a few input metrics, such as activation, retention and conversion.
What a north star metric is
A north star metric focuses the whole team on one outcome that reflects users getting value. When it grows, the business should grow too.
It is different from revenue or downloads, which can rise without users getting real value.
Qualities of a good north star
A good north star reflects value delivered, is measurable regularly, can be influenced by product and marketing work, and leads to revenue over time. It should be easy to explain.
Avoid vanity metrics such as total downloads, explained in ASO KPIs.
Examples by app type
A fitness app might use workouts completed per week; a meditation app, weekly meditators; a marketplace, completed transactions; a messaging app, daily active senders; a learning app, lessons completed.
Each counts users doing the thing the app exists for.
Input metrics
Input metrics are the levers that move the north star: new users, activation, frequency of use, retention and conversion. Teams own specific inputs.
Store metrics such as conversion rate and installs feed the top of this tree.
How ASO connects
ASO brings in the right users, which affects activation and retention as much as volume. Keywords and screenshots that attract mismatched users inflate installs but not the north star.

Choosing yours
List candidate metrics, check whether each correlates with retention and revenue in your data, and choose the one most tied to value. Test the choice with the team: everyone should understand how their work moves it.
Revisit the choice when the product or business model changes.
Activation and the aha moment
Most north star metrics depend on users reaching their first moment of value quickly. Our app activation and aha moment guide explains how to find and shorten it.
Activation is often the biggest early lever.
Reporting the north star
Report the north star weekly with its input metrics, segmented by acquisition channel, platform and country. Annotate releases and marketing changes.
See ASO reporting dashboard setup.
Common mistakes
Common mistakes include choosing revenue as the north star, picking a metric the team cannot influence, tracking too many top metrics, and never revisiting the choice.
Another is optimizing the north star in ways that hurt user experience, such as forcing extra sessions.
When to change it
Change the north star when your product strategy shifts, for example from single-player to social, or from free to subscription. Keep history so trends remain comparable.
Changing too often confuses the team, so treat it as a yearly decision unless strategy changes.
A worked example: a recipe app
A recipe app first tracked downloads, which grew while usage fell. It switched to recipes cooked per week, measured by users marking a recipe as cooked. Activation work, such as a quicker first recipe suggestion, became the priority.
The team also changed store screenshots to show quick weeknight recipes, attracting users who cooked more.
North star for marketplaces
Marketplaces need value on both sides, so many use completed transactions or matches as the north star. Input metrics then cover supply, demand and the success rate of matches.
Track each side's activation separately so one side's growth does not hide the other's problems.
Key takeaways
Pick one metric that reflects users getting value, support it with input and guardrail metrics, segment it by channel and country, and report it weekly.
Let ASO and acquisition choices be judged by how they move the north star, not just installs.
Questions to test your choice
Would this metric rise if users got more value? Could it rise while users are unhappy? Can every team name an input they influence? Does it predict revenue in your data?
If any answer is weak, refine the metric before committing.
Communicating the north star
Share the north star and its trend in every team meeting and release review. Explain how each project is expected to move it.
When people understand the link, they make better trade-offs in daily decisions.
North star for subscription apps
Subscription apps often pick a metric like weekly active subscribers using the core feature, which captures both value and revenue. Pair it with trial-to-paid conversion as an input.
See subscription app pricing strategy for related metrics.
North star versus OKRs
OKRs set goals for a quarter; the north star stays stable for longer. Teams can set quarterly objectives that move input metrics, such as improving activation or conversion, all pointing toward the same north star.
This keeps short-term goals aligned with long-term value.
Guardrail metrics
Pair the north star with guardrails that must not get worse, such as crash rate, average rating, refund rate and unsubscribe rate. Growth that damages guardrails is not real growth.
Track guardrails on the same dashboard as the north star, using crash rate and store ranking as one example of why they matter.
Segmenting the north star
Break the north star down by acquisition channel, country, platform and user cohort. A rising total can hide a weak segment, such as users from one ad network who never reach value.
Segment reports show where to focus ASO and acquisition.
How to do it, step by step
- List candidate metricsFocus on users getting value.
- Check links to retention and revenueUse your own data.
- Pick one north starEasy to explain and influence.
- Define input metricsActivation, frequency, retention, conversion.
- Report weeklySegment and annotate changes.
Before and after examples

Why it works: Value delivered beats vanity volume.
Each team tracks different goals.
Each team owns an input to one north star.
Why it works: Alignment speeds progress.
Keywords chosen for volume.
Keywords chosen for users who activate.
Why it works: Better users move the north star.
Action plan
- Tie the metric to value
- Check correlation with revenue
- Define inputs
- Align team ownership
- Report weekly
- Revisit yearly
Metrics to monitor
- North star metric
- Activation rate
- Weekly active users
- Retention
- Conversion to paid
Record the baseline, release date, audience, markets, and external changes before interpreting movement. Rankings and conversion are useful signals, but a decision is stronger when activation, retention, and business value confirm that the page attracted the right users.
Frequently asked questions
What is a north star metric?
The single metric that best captures the value an app delivers and predicts long-term growth.
Should revenue be my north star?
Usually not. Revenue follows value; choose a metric that reflects users getting value.
How many north star metrics should I have?
One, supported by a few input metrics.
What are input metrics?
Levers that move the north star, such as activation, retention and conversion.
How does ASO affect the north star?
ASO decides which users arrive; attracting the right users improves activation and retention.
When should I change my north star?
When product strategy or the business model changes significantly.
