About this app

Mnemosyne, named for the Greek goddess of memory, is an app designed to aid one in remembering lists of related information. This particular memorization scenario is underserved by more traditional flashcard/memorization apps such as Anki.

For example, if one is learning German, one would eventually have to memorize a list of around 50 verbs that are the so called "dative verbs". One could try to make a really big singular flashcard, or attempt something like cloze deletion, but these are very clunky methods. With Mnemosyne, one can simply enter the list items one at a time and get feedback on which ones were missed. One could then focus on just those items that are commonly missed or continue trying to get a perfect score on the original list.

For convenience one can import a csv file into the app to create lists, or just create them manually. The csv must have a header row with the columns "Title" and "Items". Separate each item in the items column by the separate delimiter "#@!". Within a csv file, can specify multiple lists, one in each row. One can also export lists to save elsewhere.

There is a feature that allows for placing related lists together in a collapsible group. One can nest these groups to near arbitrary depth. One creates a group by prefixing the group title to the list title, followed by "::". For example, to create a grouping of German lists, where one wants a list of nouns and a list of verbs, one would name the two lists German::Nouns and German::Verbs.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.zarathustra.mnemosyne is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

No earlier build is on record for Mnemosyne, so there is nothing to roll back to yet. When a second version is published, this section will explain how to move between them safely.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of Mnemosyne, and a listing is removed when the evidence for it stops holding up.
