What do DAU and MAU mean?

DAU is daily active users, the number of distinct players who play on a given day, and MAU is monthly active users, the distinct players who play within a month. Both count unique players over their window, measuring the size of your active audience daily and monthly. They are core scale metrics for how many people are actually playing.

What does the DAU/MAU ratio tell you?

It measures stickiness, what fraction of your monthly players show up on an average day. A high ratio means players return very frequently (many monthly players play daily); a low ratio means occasional play. It roughly approximates how many days per month an average player plays, making it a compact signal of how habitually your audience engages.

How do bugs and crashes affect DAU and MAU?

Indirectly but really: bugs, crashes, and frustrating experiences drive players to churn, and churned players stop counting toward DAU and MAU, so instability quietly shrinks these numbers. A drop in active users or stickiness can have a quality cause, which crash and bug monitoring can surface, so keeping the game stable helps sustain the active-user base.

What Are DAU and MAU?

Quick answer: DAU (daily active users) and MAU (monthly active users) count the distinct players who play in a day and in a month, respectively. They are core measures of your active audience size, and the DAU/MAU ratio, what fraction of monthly players show up on a given day, is a widely-used measure of how 'sticky' or engaging a game is.

DAU and MAU are two of the most commonly cited metrics in games and apps, shorthand for the size of your active audience. They sound simple, and they are, but they carry a lot of meaning, especially in relation to each other. Understanding what DAU and MAU measure, and what their ratio reveals about engagement, gives you a clear read on both how big and how engaged your player base is.

What DAU and MAU Count

DAU, daily active users, is the number of distinct players who play the game on a given day. MAU, monthly active users, is the number of distinct players who play within a given month. Both count unique players (a player who plays five times in a day still counts once toward DAU), so they measure the size of your active audience over those windows, how many real people are actually playing, daily and monthly.

These are fundamental scale metrics: they tell you how many active players you have, which underlies almost everything else. A growing DAU and MAU mean a growing active base; shrinking ones mean erosion. They are the headline numbers for audience size, watched to gauge whether the game is gaining or losing players over time.

The DAU/MAU Ratio and Stickiness

The relationship between DAU and MAU is often more revealing than either alone. The DAU/MAU ratio, daily actives divided by monthly actives, measures what fraction of your monthly players show up on an average day, which is a proxy for engagement frequency or 'stickiness.' A high ratio means players come back very often (a large share of monthly players play daily); a low ratio means they play occasionally within the month.

Intuitively, the ratio approximates how many days per month an average player plays. A ratio of 0.5 suggests the average monthly player plays about half the days, very sticky; a ratio of 0.1 suggests they play only a few days a month. This makes the DAU/MAU ratio a compact engagement signal: it captures not just how many players you have but how habitually they play, which is central to a game's health and especially important for games that depend on regular engagement.

Active Users, Engagement, and Quality

DAU and MAU describe your active base, but they are downstream of the things that determine whether players keep coming back, including quality. Bugs, crashes, and frustrating experiences erode the active base: players who churn (often driven away by technical problems) stop counting toward DAU and MAU, so instability quietly shrinks these numbers. A drop in DAU/MAU or in the stickiness ratio can have a quality cause worth investigating.

While DAU and MAU themselves come from analytics, the quality factors that influence them are exactly what crash and bug monitoring surfaces. Bugnet's crash and bug reporting reveals the technical problems driving players away, the issues that, by causing churn, suppress your active-user numbers. Watching your active-user metrics alongside your stability metrics connects the dots: if engagement is slipping, your crash and bug data may show technical reasons players are leaving. Keeping the game stable and bug-free removes a drag on retention and therefore helps sustain the DAU and MAU that measure your living, returning audience.

DAU and MAU size your active audience; their ratio reveals how sticky it is. And instability quietly shrinks both, churned players stop counting.
