If you have jailbroken iDevice, apart from using Cydia and various package repositories, you can also download and install .deb packages manually.
First, go to Cydia and download Filza file browser app (its free).
Then download deb package (if downloading in Safari, after tapping download link, select Open in “Filza”).
You should see downloaded package in Filza. Tap on it to open information screen, and select Install.
Once installation is done (you’ll see bash-4.0# prompt in terminal) select Respring. This will reset springboard and show application on your home screen.
If the application doesn’t show up on home screen (or if all jailbreak apps disappear from home screen – don’t panic), it means that the app does not support iOS version that you have on your device. Open Cydia, select “Installed” option at bottom menu and then select “Recent” at the top. Tap on the application you just installed and select “Remove”. Also use this method to remove any custom installed apps that you don’t want on your device any more.
