MultiLocale
APK
A simple app that enables you to add additional (or "unsupported") languages to your device's locale settings, if the OEM (*ahem* **Xiaomi**) doesn't let you. Some OEMs, particularly Xiaomi with MIUI/HyperOS, limit users to selecting only one language or locale. This restriction can lead to issues, such as apps displaying incorrect characters due to Han unification, where characters in one language may appear in another. For example, without Japanese added as a locale, apps may show Chinese characters instead of Japanese ones.

Museum of a broken API
APK
Please install usageDirect instead of this app if you are interested in system usage statistics. This app reflects my experience with the usagae statistics API from a few Android versions ago. It may no longer be current and this app is no longer being maintained. The Android system collects app usage statistics in the background; however, native Android contains no way to read out this data properly. That is why I wanted to create a tool to display it. Unfortunately, I had to learn that this data source was riddled with bugs and highly unreliable. Thus, I converted this application into a museum. It exhibits aggregated usage statistics per day for usually the past ten days, per week for the past four weeks, per month for the past six months as well as data aggregated by year. As a special exhibition, it can display this data as charts. Design-wise, the app comes in the style of the settings app to highlight that this API is a part of the Android system. An included Guide to the exhibition names some of the issues you can expect to find on your tour.

Old prices are indicated by icons and a simplistic inflation adjustment is applied to try to keep them somewhat useful, although for best results you should update the prices yourself. You can view a price’s history if you want to see how it has changed over time.The app will make a recommendation as to whether a price is good, OK or bad if it has enough information. A list of unit prices is also shown so you can decide for yourself.Customer loyalty scheme discounts can be specified for each store and these will be used to adjust the unit price when making a comparison between stores.Unit conversions are handled automatically, both within and between measurement systems.
