Player estimates

Nobody publishes how many people play Memento Mori, so these figures are modelled from the public counts on Google Play, App Store, Steam. Each count stands in a roughly known ratio to a population — one Play rating per ~45 players, one Steam review per ~35 owners — and the estimates below combine those readings, weighted by how much each source can be trusted to speak for the whole game. Read the range as the answer and the headline as its middle.

Only the games with a PC port appear here, but where Steam does report it is a real concurrent-player count rather than a proxy for one.

Not tracked for Memento Mori: Discord, Reddit, YouTube, Twitch. A platform appears here once the game has a link to it — most mobile games have no Steam port or subreddit, so a gap is normal rather than a sign the game is small.

Storyline

There are girls who many call “witches.” Although they themselves are ordinary, they can wield slightly extraordinary powers. However, when calamity spreads throughout the land, witches begin to be feared and detested.

If we kill them, then the calamity will vanish along with them!” Witches are executed one by one. But one day, as madness seizes control of the world, it is suddenly overrun by “Curses.” A country incinerated by hellfire. A kingdom consumed by crystals. An empire purged by the Tree of Life. Such are the woeful desires of those who are called “Witches of Qlipha.” Without any means to defend themselves, nation after nation falls into ruin, until finally— The fractured land is sent adrift high into the sky. Meanwhile, the people have yet to take notice. From within these girls cursed to be witches, there emanates glimmers of hope. In order to save their decimated world, these girls set forth liberating the land from darkness. For they believe that it is the right thing to do...

Frequently asked questions

How many people play Memento Mori?

We estimate that about 1,300,000 people have played Memento Mori — plausibly between 290K and 3.9M. Around 64,000 of them play on a given day, in a range of 2.9K and 590K. Both figures are modelled from public counts on Google Play, App Store and Steam rather than published by the developer, so read them as a scale rather than as a headcount.

Is Memento Mori still active?

Yes. Memento Mori is holding steady — it measured within a percent of where it was a week ago. We recheck every source daily, and the charts on this page show each platform's readings over time.

How are the Memento Mori player estimates worked out?

Nobody publishes player counts for mobile games, so we infer them. Each public count we can read is converted into a population using a documented ratio — roughly one Google Play rating per 45 people who played, one Steam review per 35 owners, one Discord member per 40 players — and the live counts (Steam concurrents, members online, Twitch viewers) are converted the same way into a daily figure. Those separate estimates are then averaged in proportion to how much each source can be trusted, which is why sources that disagree widen the published range instead of cancelling out. This page is built on 2 readings taken since August 8, 2026.

When was Memento Mori released?

Memento Mori was released on October 18, 2022 for Android and iOS.
