Scheduling Event Management

Fossify Calendar

Android

Platform information checked 2026-10-19. The F-Droid calendar is free and works without a Fossify account or a Fossify sync subscription. The separate paid Thank You app funds Fossify and adds customization/shared settings to supported apps. Calendar synchronization uses accounts or calendar providers already configured on the device; Fossify does not run a sync service. Those services can have their own costs. This replaces event planning, reminders and calendar views rather than every Business Calendar 2 Pro feature.

Official app downloads and supported devices

Use the publisher’s linked store or documented APK channel. AltStack does not host APK files. A player or independent client does not grant access to paid subscription content.

Keep events, recurring reminders and calendar widgets on your Android phone.

Installation and setup

Install on your phone or supported device · Instructions checked 2026-10-19

Use the official Fossify Calendar app page to open its F-Droid listing. Confirm package org.fossify.calendar and a compatible Android version; the current F-Droid build requires Android 8.0 or newer.
Install through the F-Droid client and open Fossify Calendar. Allow calendar access and reminder-related permissions for the functions you choose to use.
Use the local calendar views for events and reminders. To synchronize, configure an Android calendar account/provider separately; Fossify Calendar has no Internet permission and does not supply a sync server.
Keep using the selected store for updates. When switching between Play and F-Droid, back up app data and choose the same or newer version as documented by Fossify.

Calculators & Unit Conversion

Free calculator · online currency rates

Handle calculations and common unit conversions in one Android app.

The provider describes Unitto as free, with no ads, in-app purchases or analytics. Ordinary calculations and unit conversion run locally; currency conversion needs Internet access. The GPL-3.0 source and usable F-Droid edition are available. The browser version is alpha, has limited language/theming support and loses user data on reload. This is a calculator/converter alternative for part of a WolframAlpha workflow; it does not include WolframAlpha’s knowledge database, cloud symbolic engine or every guided Pro solution. The alpha web build includes additional GPL-2.0 and MIT components with separate provider notices; the Android edition is the free app reviewed here.
