Best Teleprompter for an iPhone

A teleprompter uses a piece of angled two-way glass, called a beamsplitter, mounted in front of the lens. Your script is displayed on a screen below the glass, which reflects the words back up to you, while the camera behind the glass sees straight through to you. Because the text appears to float over the lens, you can read it while looking directly into the camera, so you keep natural eye contact with your viewer.

Everything that makes prompted delivery look natural comes down to one thing: how far the text sits from the lens axis.

A beam-splitter rig solves it properly. The glass sits at 45 degrees in front of the lens, the phone lies flat below it with the script mirrored, and the camera shoots straight through the glass while you read the reflection. Your eyes land on the lens itself, which is why broadcast presenters can hold a camera's gaze for ten minutes. The teleprompter has worked this way since the 1950s.

Without a beam splitter, the fix is distance. Put the reading phone as close to the lens as you can and then back the whole rig away from yourself. The angle between lens and text is what the viewer notices, and it shrinks as you move further back, which is why a prompter that looks obvious at arm's length looks fine from two metres.

Two setup details do most of the remaining work. Mirror the text if you are reading off glass, because the reflection reverses it, and every prompter app has a mirror toggle for exactly this. And get the reading surface level with the lens rather than below it: reading downwards reads as shifty on camera in a way reading slightly upwards does not.

If you film on the iPhone itself, a compact beamsplitter prompter designed for phones is the best value. Your iPhone clips in as both camera and script screen, or a second phone shows the script, and a free or low-cost teleprompter app scrolls the text at an adjustable speed. These rigs cost little and pack away small, which suits creators filming pieces to camera on a phone.

If your main camera is a mirrorless or webcam on a desk rather than the phone, an all-in-one prompter such as the Elgato Prompter is the easier long-term tool. It builds its own screen into the housing, so there is no phone to mount or mirror, and it can display a script, notes or even a video call reflected over the lens. It costs more than a phone rig but removes the fiddliness, which matters if you record to camera often.

There are three tiers, and the jump between the first two is much bigger than the jump between the second and third.

The honest guidance is to start at the top of that list rather than the bottom. A prompter app costs nothing to try, and it tells you whether you actually like reading to camera before you buy glass. Plenty of creators find they deliver better from bullet points and never need the hardware.

The trick is to not sound like you are reading. Write your script the way you actually speak, in short, plain sentences, and set the scroll speed a touch slower than you think you need so you are never chasing the text. Look through the words to the lens rather than scanning them, glance away occasionally as you would in conversation, and record a practice pass to settle your pace. A little rehearsal turns obvious reading into natural delivery.

Match the scroll to your natural speaking pace rather than trying to match your pace to the scroll. Conversational delivery sits somewhere around 130 to 150 words a minute for most people, and presenting to camera usually lands at the slower end because you are enunciating more.

The practical method is to record yourself reading a paragraph at a comfortable pace, count the words, and set the app to that figure. Then leave it alone. Chasing a scroll that is slightly too quick is the single most common reason prompted delivery sounds rushed and flat.

How the script is formatted matters as much as the speed. Short lines with hard breaks at natural pauses read far better than justified paragraphs, because your eye grabs a whole line at a time. Many creators go further and prompt from bullet points rather than full sentences, reading the idea and then saying it in their own words, which keeps the delivery loose while still preventing the mid-take blank.

Three things surprise people, and none is a reason not to use one.

Glass costs you light. A beam splitter passes only part of the light through to the sensor and reflects the rest, so the image is darker than the same shot without it. In a well-lit room this is a non-issue; in a dim one it means opening up or adding light.

Reflections land on the glass. A bright window or a lamp behind the camera will show up in the beam splitter, and the usual fix is the hood most rigs include, or moving the offending light rather than the rig.

Close range still shows. Beam splitters put the text on the lens axis, but at very short subject distances the eye movement across a line of text is still visible. Shorter lines and a slightly longer working distance both help.

The broader limitation is editorial rather than technical: a prompter makes you accurate, not interesting. Scripts written to be read tend to sound written, and the creators who use prompters well generally write the way they speak first, then prompt from that.
