If you have come here looking for how to use Memento Mori on Android, it is worth clarifying one thing from the beginning: there are two different products that share a name. On the one hand there is a simple productivity app which reminds you that time is finite and shows you your life expectancy. On the other hand, there is MementoMori: AFKRPGa mobile video game with a strong focus on art and music. In this guide I explain how to take advantage of the app on Android and, to avoid confusion, you also have a complete review of the game, its systems, characters and resources.
We are going to cover everything in detail and with clear language. We will start with the minimalist app Memento Mori (that of the vital reminder), and then we will delve into the title MementoMori: AFKRPG with its system of summons, coins, missions and a selection of witches highlighted by levels. This way you will have a comprehensive vision without leaving anything important along the way, and you will know how to identify which Memento Mori you are interested in using in your Android mobile.
The Memento Mori app on Android: what it does and how to take advantage of it
This tool is ideal if you want to have a view of your estimated life and a gentle reminder that every day counts. After a very brief initial setup, the app displays three key pieces of information: an estimate of your life expectancy, the time you would have left expressed in years, months, weeks and days, and the approximate percentage of your life already lived.
One of its most practical options is the mode lock screendesigned to leave the information visible on the desktop of your mobile phone or tablet. So, every time you look at the device, you get a positive wake-up call to focus on what matters and enjoy the moment. Additionally, the app is available for free downloadand the developer encourages you to leave questions or suggestions, even through platforms like itch.io, so that the feedback helps improve the experience.
To use it on a daily basis, there is no more mystery than opening it often and making conscious decisions: postpone a distraction, call a loved one, or dedicate some time to that project that you always leave for later. That’s the approach: an app simple and direct which works as a constant reminder, without complicated menus or dozens of settings. If you like having it visible, activate its lock screen mode and use it as a little visual anchor to your priorities.
MementoMori: AFKRPG on Android: Overview
Making the difference with the app clear, we move on to the game MementoMori: AFKRPG, a mobile title developed and published by Bank of Innovation INC which launched globally on October 18, 2022. This idle RPG competes in the same league as giants like AFK Arena and Idle Heroes, and arrived after surpassing one million pre-registrations. It is available for free at Google Play and in the iOS App Store, with optional purchases of cosmetics and in-game currencies.
Its proposal is very oriented towards those looking for a relaxed experience. The main focus is placed on the music and artwith a top-level sound section and an unmistakable visual style. The playable loop is intentionally simple, relying on AFK progression to keep you progressing even when you’re not playing, and this can feel shallower than other idles if you’re looking for a dense tactical layer. For those who value audiovisual packaging and a gentle rhythm, this MementoMori fits like a glove in Android.
If you like to play on a computer, the game can also be enjoyed on PC via emulator, with frequent recommendations to use BlueStacks along with keyboard and mouse. It is not essential, but on large screens the animations and artistic direction look better.
Invoke: the summoning system (gacha)
As a hero collector, MementoMori relies on a system of gachapon to get characters (here called “Witches”). The summon function is unlocked after finishing the tutorial and you will find it in the main menu. There are several summon banners with different mechanics and currencies, and it is worth knowing them to optimize your throws:
- Cursed Prayer Banner– Allows you to summon witches of rarity N to SR using Diamonds. It is a permanent banner, ideal to pull when you accumulate the premium currency.
- Prayer Banner of Beginnings– Exclusively offers witches of SR rarity. Works with Start Tickets and it is also permanent, very useful at the beginning to ensure quality.
- Friendship Prayer Banner– Summons from rarity N to SR with Friend Points. It’s a free path to progress if you coordinate with your friends list.
- Amber Prayer Banner: spend Tickets of Souls and rotates its featured witches daily, an interesting option for pursuing specific units.
The probabilities depend on the raritynot from the banner: SR 4.46%, R 43.77% and N 51.77%. You can summon one at a time or ten at a time, and the game applies a “pity”: every 10 summons there is a guaranteed SR. With this, progress becomes more constant even if luck is not on the side. given moment.
Summon Coins available:
- Diamonds: the premium currency; They are used to roll in the Cursed Prayer.
- Start Tickets: a pack of 10 guaranteed rolls in the Prayer of Beginnings that ensure an SR, available, for example, in Premier Gifts.
- Friend Points: are obtained and shared among friends; are spent on the Friendship banner.
- Tickets of Souls: used in the Prayer of Souls/Amber with rotation of highlights.
Key coins to progress
As in many idle RPGs, here you find several currencies. The three most important to move forward fluently are GoldDiamonds and EXP Orbs. Understanding its use greatly speeds up progression, especially in the first chapters of the story.
Gold– Easily achieved through AFK (Inactive Chest) rewards, quests, achievements and events, and even as compensation after maintenance. It is spent on practically everything: raising witch levels, improving equipmentor buy at the market. It is abundant, but you will also burn it at a good rate.
Diamonds: the premium currency of the game, much scarcer unless you pay. Its main use is for invocations in banners. They can also drop through daily quests, events, story chapters, or as compensations. If you go free-to-play, it is advisable to reserve them for key moments.
EXP Orbs: essential to level up both the witches and your account. The higher the player level, more modes you unlock. The best source, once again, is AFK rewards, so consistency checking the chest goes a long way.
How to make your witches stronger
As you progress, you will notice spikes in difficulty. In MementoMori, it is important to focus resources on a core of five witches and push them headlong, since repetition and infinite farming are not on the table. It’s a 100% game PvEso the main story and offline challenges set the pace.
Level up: the most direct method. As you level up, base stats such as Health, Defense, Attack or Speed grow, and by improving these numbers, skills scale better. For example, a skill that deals damage as a percentage of Attack hits harder if you have invested in that attribute. To level up you spend Gold and EXP Orbs. Every 10 levels you will need Kindling Orbs to upgrade your grade and sometimes unlock new skills.
Wake up– Increases a witch’s rarity and base stats, but requires duplicates of that character. High echelons can order 2, 3 or even 5 copies. This is where SR’s pity every 10 summons helps keep you from getting stuck for too long. too long.
Equipment: the other great lever. There are six types of pieces to complete the slots: Weapon, Armor, Rudder, Vest, Gloves and Boots. The pieces provide extra statistics and, well tuned, make differences in survival and damage.

Story, sound and official links
The world of MementoMori is tinged with tragedy and hope. There is talk of girls designated as “witches”, with slightly extraordinary powers, persecuted by the Church of Longinus during the “Witch Hunt.” When madness takes over the land, “Curses” arise that devastate countries: one kingdom consumed by crystals, another by the Tree of Life, and chaos ends up fragmenting the earth until it rises to the heavens. In this scenario, glimmers of hope emanate from the fragile hearts of these girls, and they set out to free their world from the darkness because they believe it is the right thing to do. As the tone of the game goes, all paths end up leading to an inevitable goodbye, and the narrative sensitively underlines this.
At the gameplay level, you can switch between automatic battles easy to use and a point of strategy in composition and equipment. The Live2D animations provide dynamism, the idle system makes you grow even offline, and advancing in the story unlocks content extra. Fine-tuning your gear allows you to precisely influence how girls climb, and guilds provide a social space to coordinate and compete to be the strongest.
The sound is the protagonist: each witch has her “Lament”, a song that expresses her emotions, and the soundtrack, of high quality, is above the standard of the medium. The game recommends use headphones to enjoy it to the fullest. Among the cast and voices, top-notch artists and seiyuus are listed, and here is a sample of the Japanese cast along with the performers of their songs:
- Illya (CV: Kana Hanazawa) – Song: Daoko
- Iris (CV: Inori Minase) – Song: Hakubi
- Rosalie (CV: Sumire Uesaka) – Song: Sayaka Yamamoto
- Soltina (CV: Yoshino Nanjo) – Song: Koresawa
- Amleth (CV: Atsumi Tanezaki) – Song: Atarayo
- Fenrir (CV: Minami Takahashi) – Song: Kano
- Freesia (CV: Yui Horie) – Song: Sonoko Inoue
- Belle (CV: Yuu Asakawa) – Song: 96NEKO
- Luke (CV: Ami Koshimizu) – Song: Ayaka Hirahara
- Carol (CV: Hina Tachibana) – Song: kurokumo
- …and many more collaborations
The previous list corresponds to the Japanese version, but from settings you can toggle the voices between English and Japanese. If you want to follow the news or watch special videos, here are the official channels: Web, X/TwitterFacebook and YouTube. The entire set is powered by Live2Dwhich explains the attractive visual finish.
As you see, “Memento Mori” can refer to both a minimalist app that helps you live more mindfully and an idle RPG with an emphasis on music, art, and the stories of its witches. On Android you can install both: use the application to see your life expectancy and activate its sleep mode lock screenand when you feel like disconnecting, enter the game to progress with the AFK system, shoot at its banners (with guaranteed SR every 10), take care of your coins (Gold, Diamonds, EXP Orbs), complete daily and weekly missions, and bet on top witches like Fenrir, Olivia or Cordie. If you prefer a big screen, remember that you can always play the RPG on PC with BlueStacks and enjoy its sound section with headphones.
