Read the opening message carefully to understand application's limitations. This app is meant for short videos and there is some lag experienced on older phones due to the amount of processing power required to apply filters to live video.
Video writing is done in 1920x1080 resolution with the exception of VHS filter which is 640x480. Photo quality outputs lower than usual due to internal methods required for applying filters.
The application uses resources heavily and will trigger warnings when phone system pressure is elevated (heat is indicator). Heed the warnings; I am not responsible for any damages. More information can be found here at Apple's developer documentation.
Limitations:
• Results will vary depending on phone status (number of apps open, running time, etc.)
• Cannot take still pictures while on Static Effect
• Kaleidoscope and Bump Distortion are not centered on iPads
• If the app is put into background mode while recording for a small duration the video will not save
• Older devices which experience lag while switching filters can put app into background then reopen to speed up
