In short: True-Slate is made by Andy Dodd, a working filmmaker at Iron Triangle Films in the UK. It started as the slate he wanted on his own sets, and grew into a small family of apps for film crews: True-Slate, True-Prompt and True-Script.
Every shoot needs a slate. A whiteboard clapper is cheap but slow to update, easy to misread across a room and useless for timecode. A proper timecode slate does the job beautifully, but it costs as much as a lens and is one more box to charge, carry and insure. Most of the crews I work with already carry an iPad or an iPhone, so the question was simple: could that device be a slate good enough to trust on a real set?
True-Slate is the answer I built. It shows scene, shot, take and roll in big, high-contrast type you can read from the back of a location. It jams to LTC timecode from a sound recorder, generates LTC of its own, handles every common frame rate including drop frame, and logs every take so the edit has notes from the floor. It does the things a hardware slate does, without the price tag.
All three True apps follow the same rules, because they are the rules I want from software myself:
True-Slate is the digital clapperboard with real timecode. True-Prompt is a teleprompter that follows your voice and mirrors for beam-splitter rigs. True-Script lets you write a screenplay by speaking, formats it as you go and reads it back as a table read. They share one look and one philosophy, so a crew that uses one feels at home in the others.
This site explains what the apps do, offers guides on timecode, slating and on-set workflow, and hosts each app's support and privacy pages. The guides are written from experience on real productions. If something is unclear or out of date, please tell me and I will fix it.
