Timelapse Toolkit vs LFTools

Timelapse Toolkit is very helpful if you shoot timelapse with DSLR cameras (Watch the video at timelapsetoolkit.com).
 It offers tools like the timelapse calculator, which unlike others, is able to calculate different values. It can be used to calculate the total length of the clip, as well as the duration of the event, and of course the interval between the shots.
It comes with other features such as a torch, very handy when shooting at night, a Sun and Moon tracker, to know the time of sunset, sunrise, moonset and moonrise. Also includes a page with tips on how to get the best results in your timelapses.

LFTools is an app for Large Format and Film Photographers. In version 1.5.0 LFTools contains 2 Tabs. The first one is the 'LF Tools' tab, with several sub sections. Each section has a tool to calculate certain properties which are used in large format photography. Like extended exposure times with regard to bellows extension or the magnification from a bellows draw for a given focal length. The second tab, 'Film Reciprocity', contains the Film Reciprocity Calculator. This calculator is of interest for all film photographers who are interested in long time exposure. With the Film Reciprocity Calculator one can overcome the so called reciprocity failure, which is inherent to almost all films. It is quite simple to use, one just has to select a film, shutter speed and aperture an the tool automatically creates a table with extended exposure times. The app comes with a pre-populated list of films from Ilford. Ilford was the only manufacture who publishes the p factor for their films. Al be it, the user can add its own films for calculation.
