Flex is a tweak which allows you to do your own tweaks. It’s not availible on Cydia for the moment, but it will be soon.
What can you do with flex? You can create your own tweaks “without knowing anything about Objective-c”. This idea is from John Coates, who made MissionBoard pro, and it will allow you to make and share your runtime patches, not just on iOs but also on any apps you have installed.
The developer thinks that it can be for developer and for others users :
You basically search for a keyword that’s related to what you want to change.
Say you want to increase the amount of tabs Safari can have. So you make a new patch, and search for “maximum”. You’ll find two results, one which says “maxiumumTabDocumentCount” You click it, change the return value to 30 and suddenly you can have 30 Safari tabs.
What do you think about this idea?
Original Reddit post :
For the past few weeks I’ve been working on a rather large project. It’s a new jailbreak app called Flex. What it does it let you create small tweaks, share what you create, and download others’ shared tweaks. I expect to release it pretty soon, just need to have it go through a beta phase.
To give you a better idea here’s a screenshot of the patches view. Each of those patches consists of one or more “units”. A unit looks like this, and it’s what does the work.
You can instantly download patches from within the app, and activate them straight away.
Patches are very easy to make, and give you quite a lot of power. You can make them for any application you have installed, even SpringBoard. They don’t contain any real code, the tweak portion of Flex is actually what does all the heavy lifting… so basically these patches can’t be installed outside of Flex.

I got a great response about the beta testing, and I no longer need any more beta testers. Watch for Flex’s release soon, and if you want to get e-mailed about it you can subscribe to TweakTuesday
