Editor's Overview

Guessaday is a party game application developed by Moritz Firsching, packaged as a single Android APK of version 1.0 weighing in at 1.73 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 1.73 MB, so it installs quickly even on modest connections.
  3. This build is signed by "Moritz Firsching" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

A trainer for calculating the day of the week of any given date.

This app displays a random date and asks you what day of the week that date is.
Then it checks your answer. Optionally it measures how long it took you. In the
settings you can configure the range for the random date.

If you want to learn how to do this calculation, check out on the developer's
website!

Frequently Asked Questions

Is Guessaday free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does Guessaday require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is Guessaday safe to install?
We link to the exact APK published by Moritz Firsching. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update Guessaday?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
