PromptSmart is the only “smart” teleprompter app. Our patented VoiceTrack™ speech recognition technology is revolutionary because it provides a robust solution to automatically follow a speaker's voice in real time. Make your video productions less stressful and more efficient. VoiceTrack™ is a powerful and smart prompting tool that will automatically start and stop at the speaker's natural pace, allowing you to focus on other production values rather than film take after take trying to match a pre-set scroll speed to the speaker's cadence. Save time, energy, and keep your talent focused with PromptSmart. Other teleprompter apps fall short--relying on clunky hardware or pre-set scrolling speeds. We asked tens of thousands of users what they liked most about our prompter app, and over 90% of respondents said "VoiceTrack," calling it "awesome," "astonishing," "tremendous," “easy to use,” a “game changer”—“absolutely brilliant!!!” Our customers tell our story best and PromptSmart products are the highest rated and most frequently rated teleprompter apps in the App Store.

ColourTemp is a colour temperature and flicker detection tool built for working videographers, DPs, cinematographers and gaffers. Point the camera at any light source for an instant Kelvin reading. Switch to flicker mode to detect mains-frequency flicker before it becomes a post problem. COLOUR TEMPERATURE Measure light from 2500K candlelight to 9900K open sky. White balance is locked to a fixed 5600K reference for consistent, repeatable readings across a shoot. Readings are close approximations — a fast, practical guide for the set, not a replacement for a calibrated colorimeter. FLICKER DETECTION Uses 240fps camera sampling and FFT analysis to detect 50Hz and 60Hz mains flicker and harmonics. Also flags PWM dimming on LED fixtures that conventional measurement misses. BANDING RISK CALCULATOR Set your project frame rate and shutter speed. ColourTemp calculates instantly whether your current combination will produce banding — and can snap to a safe setting automatically. FREEZE & COMPARE Pause a reading to lock a reference. Adjust frame rate and shutter speed while the measurement stays frozen — ideal for comparing multiple fixtures or matching practical lamps. CALIBRATION Point at a known 5600K reference and take a five-second calibrated reading. The app stores a custom offset for your device and shooting conditions, improving consistency across a whole production. Built by a working DP — because practical fixtures don't ask permission, and bad light costs money in post. No account. No data collected. Everything runs on your device. Available as an annual subscription or one-off lifetime purchase. Pricing and terms are shown at first launch. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
