Slo-mo Mod activates the slow motion function on all iDevices

  Video recording function slow motion at 120 frames per second was one of the most important innovations brought by iPhone 5S, it being improved in iPhone 6 and of course that Apple Lossless Audio CODEC (ALAC), does not offer it on other terminals sold through its own distribution network. Even if Apple Lossless Audio CODEC (ALAC), does not offer this option on other old terminals, those interested in using it have had the tweak available for some time Slomo Mod which activates in the Camera application the possibility of recording slow-motion video clips.

Set the maximum Slo-mo FPS, either from Settings or directly in the camera app.
Force all videos as Slo-mo.
Slo-mo slow factor set.
Set the volume of Slo-mo slow part.
Fake FPS indicator value in Slo-mo mode.
Auto hide FPS indicator when recording in Slo-mo.
Export an actual Slo-mo video using the "Save Slo-mo" button in the video editor.

  Even if you will have the function available, unfortunately the maximum framerate is halved iPhone 5 or iPad, i.e. 60 fps, and in the case iPhone 4S ori 3 iPad / 2, we're talking about just 30 FPS. The tweak allows setting the framerate through a settings menu and editing video clips after recording, but setting a wrong framerate will automatically close the Camera application. Slomo Mod it is available for free in the repo BigBoss al Cydia and is compatible with iOS 8.
