Explained: What Is Install0us

Installous/Install0us is an application for the iPhone/iPod Touch (collectively called the iDevice). Install0us is a web browser and downloader and installer in one.


Install0us 2.5 (discontinued)

The Browse tab houses the web browser which lets you access various websites so you can search for and download stuff. It has an address bar that lets you input the website address in case you do not want to be limited to just Apptrackr.org.

The Downloads tab is a filemanager where your downloaded IPAs are listed and you can tap on them to select “Install”. Only files with extensions .ipa and .ipa.zip are shown here, although the following file types are compatible for downloading: .ipa, .deb, .zip, .ipa.zip, .rar.

You can download multiple files at the same time, because the download screen is now separate from the browser interface. You can continue surfing for more apps to download while other apps are downloading in the background. Downloaded files are located in /private/var/mobile/Downloads. If you need to have your downloads be in /mobile/Library/Downloads, delete the Downloads folder in /mobile/ and create a symbolic link to /mobile/Library/Downloads instead. Install0us 2.5 will then work as Installous 2.0 used to. Credit for this workaround method goes to ExiMoR.

Install0us 2.5 uses the native Apple installation method that all your legit apps go through. It sends the cracked ipa to the native installer (Installd) on board your iDevice which means installation is faster, cleaner, does not require dependencies and will work for everybody, as long as you follow one simple instruction and patch your Installd file. Installation is always clean and there is no need for a “dirty” toggle. If installation fails, either you didn’t get your Installd patched properly or the cracked ipa you downloaded is corrupted (maybe during cracking or during download).

The Settings tab has a bunch of options: you can set a homepage for the web browser, decide whether Install0us automatically installs downloaded ipas and/or automatically deletes them after install, and also toggle iTunes sync functionality.

When iTunes sync is on, Install0us flips a switch in the installation process that makes iTunes recognize them as syncable apps and allow you to transfer them to your computer (unlike Cydia apps and native apps like Photos).

The latest and last version is 2.5.2.the.end. Development on this has ceased, but the app will continue to run.


InstallØus 3.0 (dead)

installØus 3.0 has 5 tabs at the bottom:

  • Search
  • Updates
  • Browse
  • Downloads
  • More (Settings, About)

The Search is a native engine that taps into Doosje’s database which pulls data from Apple’s iTunes Store, so it works just like the AppStore and you always get up to date data. When you tap on an app you are brought to the app description screen, including a Downloads tab where you will see the plugins you have installed.

The plugins are user-end extensions that you can install to provide yourself with download links from your choosen cracked-app sites. Many web plugins were made by the community for various sites. A native plugin for iPhoneCake was released in the last beta before termination.

The Updates tab shows all the AppStore apps you have installed, both the purchased and the cracked ones. InstallØus 3.0 detects the app versions that you have and compares it with the latest versions that Apple has, thus keeping you informed about when the apps you are using are outdated. When you tap on an app here, you are brought to the same screen as above.

Browse, Downloads, and More are as described above in Install0us 2.5.


What you need to know if you intend to install and sync cracked apps:

  • You will need to have your Installd file patched. Read Patching the Installd.
  • You will also need one legit app from the AppStore.


Installous 2

Development on Installous had been taken over by the devs from Hackulous as of the 2.0.4 update. Install0us and Installous are no longer related; Install0us and Installous are separate apps and can be installed simultaneously on the iDevice.

In Installous 2, the browser is set to load Apptrackr.org, and there is no option for the user to input their own website address. There is also no simultaneous download functionality. Downloads are downloaded to /private/var/mobile/Library/Downloads. In the Settings menu, there is a clean/dirty toggle for the type of installation you need.

The clean method allows for update re-installations, but you still have to manually find the updates yourself. The AppStore cannot detect non-official apps, so you cannot expect to be alerted of updates. You can of course regularly check Apptrackr or other sites and see if there’s an updated crack available, and download it if so. Go back to Installous to install the update and it will modify that app to reflect the update.

The dirty method doesn’t let you update at all. Installous will just install the new ipa as a new app and you’ll end up with two icons of the same application at different versions. This method exists for times when the app is coded in such a way that clean installation doesn’t work.

To download and install Installous, open your Cydia app and add cydia.hackulo.us to your sources (under Manage -> Edit -> Add). Then select Installous and install. The latest version is 2.0.4.

The Hackulous dev team is currently working on a new installation app. Development on Installous 2 has ceased and the new app will replace it as Hackulous’ proper official installation app.

First off, What is Installous/Install0us: Explained. (link coming soon)


At the beginning, puy0 created Installous and released it under Hackulous. After version 2 was released, he went on to rename it as Install0us and released version 2.5. Eventually version 3.0 was made (also under the new Install0us name), although it never made it out of beta.

Puy0 had always wanted to make a legit app. Hiding behind a badass Big Brother (Hackulous) was not what puy0 wanted to do. He wanted the freedom to develop apps safely outside the shadows of the law with his head held high. One may argue that he would have been perfectly safe staying under Hackulous’ umbrella, but that just shows you do not understand. Puy0 didn’t want to be “safe” in terms of a good hiding place, he wanted to be out in the sun, to be clean, free, and safe. Staying behind Hackulous would only imply that what he was doing was unlawful and required backup from Hackulous. Accordingly, he moved out of Hackulous in October 09 and distributed Install0us 2.5 (and thereafter the 3.0 beta) independently.

All along he was confident that he was taking the legal route with 2.5 and 3.0 because neither of them are tied to any cracked-app sites, and neither of them actively provided download links or illegal content. But he had enough doubts to compel him to seek a proper lawyer. He eventually found a lawyer at the top of his field, specializing in Internet law and legislations. It turned out that he was not entirely in the clear, and if it were ever to go to court it would be difficult to defend his case. After a long though, he decided to quit this shady life and put a stop to Install0us development.

Install0us 3, that came with app updates and plugins, is now dead. It no longer works.

Install0us 2.5 is discontinued as of version 2.5.2.the.end. Development has ceased, but it still works. It will continue to work forever, at least until a very different iPhone OS comes out and incompatibility occurs.



When puy0 left, Hackulous didn’t feel good about it. The staff felt that they have done their part in supporting his app, keeping it updated in the Hackulous repo, and providing a platform for Installous discussion on their forum and helping their users with Installous issues, etc etc. They felt that puy0’s exit from Hackulous was tantamount to a backstab. They, Dissident in particular, disagreed with the principle behind puy0 moving out of Hackulous on grounds of legality concerns.

Also, they wanted to retain an official installation app because Installous had been part of the ‘lous’ package for so long. So they retained Installous 2 (without puy0’s approval), and, since Install0us.com was started up, did not provide support for Install0us.


The relationship between Install0us and Hackulous became increasingly strained as time went on, due in part to words uttered by members of both parties, actions taken and reactions induced, and not to mention significant prejudice and refusal on both parts to see things in another light.


To end off, now that Install0us 3 is dead, the Hackulous dev team is making their own installation application, tentatively named Installr, which will have functions similar to those in Install0us 3. Installr will eventually replace Installous as Hackulous’ proper official installation app.
