Amplissimus

Amplissimus is an app that tries to be what the DSBMobile app could have been. It currently supports Android, iOS, Linux, macOS and Windows and is a merge of Luddifee/Amplissimus and Ampless/Amplessimus.

Why not the browser?

We could theoretically build a webapp version of this with almost no effort, BUT it would require a proxy server of some kind as all mainstream browsers try to block, what is called CSRF: You open up evil.com and in JavaScript it makes a request to bank.com that tells it to send me $1000. Of course we, as well as the browser vendors should, know that making requests to DSBMobile probably cannot ever be abused in a relevant way, but that doesn't fix the problem. Proxy servers are a solution for this and, while we might one day make one, that makes it quite a bit harder to run this as a web app.

Installing

Just take the binary and install it in your OS's standard way.

Android

Download the APK and click Install.

Linux, Windows

Download and extract the ZIP and run the included binary. (on Linux you have to chmod +x it)

macOS

Download and mount the DMG and drag-and-drop Amplissimus into the Applications.

iOS

iOS installation is interesting, because, to run on iOS "officially", we would have to pay Apple $99/year.

Filza (jailbroken)

The easiest way to install any IPA is to just open Filza, go to the Downloads folder, click the file and then on Install.

Current AltStore Beta

In Beta 5 of AltStore 1.4 a new feature was added: You can add the Amplissimus source by going to altstore://source?url=https://amplus.chrissx.de/altstore/stable.json.

AltStore 1.4 Beta 1-4

Some AltStore Betas allowed you to add custom software repositories. Go to Browse → Sources → + and enter:

https://amplus.chrissx.de/altstore/stable.json

and you can install Amplissimus like you would install Riley's apps.

AltStore 1.3 and older

AltStore allows you to install IPAs. Download the IPA and install it, either with the + button in AltStore or by using open in AltStore.

Building

Compiling for everything except Windows will assume you are running macOS or Linux, but nowadays Windows should work, too. However, for all build targets a recent version of Flutter is required. In the Output sections $aid{plat,arch} means "amplissimus-version-plat-arch". (e.g. "amplissimus-4.1.42-ios-arm64") All of the outputs are placed in the bin/ folder, which is created automatically.

Android

Dependencies

• Android SDK
• A development certificate (keytool -genkey -v -keystore /tmp/amp.jks -keyalg RSA -keysize 2048 -validity 10000 -alias amp -storetype JKS)
• A bit of configuration

Compile

./make android

Output

• $aid{android,universal}.aab an application bundle
• $aid{android,universal}.apk an application package

Linux

Dependencies

• Linux (maybe some other Unixes work, too)
• Clang
• CMake
• GTK3 headers
• Ninja
• pkg-config
• appimage-builder

(pre-installed if you installed Flutter through snap) (if you use Debian*, you can apt install: clang cmake libgtk-3-dev ninja-build pkg-config and install appimage-builder)

Compile

./make linux

Output

• $aid{linux,x86_64}.zip an archive containing Amplissimus and all deps for x86
• $aid{linux,arm64}.zip an archive containing Amplissimus and all deps for ARM

Notes

You can also run ./make linux-x86_64 or ./make linux-arm64 to build just a specific architecture and ./make linux-x86_64-nai and ./make linux-arm64-nai to skip AppImage creation.

iOS

Dependencies

• macOS
• Xcode

Compile

./make ios

Output

• $aid{ios,arm64}.ipa an unsigned iOS 12.2+ app

macOS

Dependencies

• macOS
• Xcode

Compile

./make mac

Output

• $aid{macos,x86_64}.dmg an installer image for macOS 10.15+

Notes

Unfortunately the Flutter team is slow, so you have to use Rosetta 2 on ARM64.

Windows

Dependencies

• Windows
• Visual Studio

Compile

flutter upgrade
flutter config --no-analytics
flutter clean
flutter pub get
dart run make.dart win

Output

• $aid{windows,x86_64}.zip

Notes

Flutter might get Windows ARM support at some point, in a few decades.
