Fixed Speed, Timed Scrolling and Words Per Minute Scrolling are all available on iOS, macOS, Android and the web browser version. All three move your script down the screen; they just decide the pace differently. Picking one comes down to what you already know about your read.
How to switch between the modes
VoiceGlide, Fixed Speed, Timed Scrolling and Words Per Minute Scrolling all sit side by side in the same mode selector, so switching takes one gesture.
Fixed Speed and VoiceGlide need nothing typed in; the other two modes each need one number.
Fixed Speed
You set a constant speed and the script moves at that pace. On the recording screen the control is the scrolling speed bar in the middle of the screen, so you can nudge it mid-take without opening a menu. The full steps are in How Can I Control the Scrolling Speed of the Script?
Choose this if you have rehearsed the script, you know your rhythm, and you want one control and nothing else to think about.
Timed Scrolling
You tell the app how long the read should take, and it works out the scroll speed needed to finish exactly on time. Swipe to Timed Scrolling, tap Edit, and set your target duration there. Trim a paragraph later and the pace adjusts itself.
Choose this if you have a hard duration to hit: a 30-second ad, a 60-second social cut, a news read, or a conference slot with a countdown clock on it.
Words Per Minute Scrolling
Instead of a duration or an abstract speed number, you set your speaking rate. Swipe to Words Per Minute Scrolling, tap Edit, and enter your words per minute. Most people sound natural somewhere between 120 and 160, so once you know your number, every read feels the same.
Choose this if you record regularly and want a consistent delivery pace, or if a client has given you a word count and a runtime.
When to reach for VoiceGlide instead
All three modes above scroll whether you are talking or not. If you ad-lib, pause for effect, or get interrupted, you end up chasing the text. VoiceGlide listens as you speak and scrolls only as fast as you actually talk, so the script waits when you do. It works on all four platforms too. See How to Use VoiceGlide Auto Scroll to set it up.
A quick way to decide
Whichever you use, turning on the remaining-time display helps you see whether you will land inside your slot. See How Can I Display the Remaining Time While Recording?
