Read documents one word at a time, listen aloud, or browse the text with its figures in place.
Reading modes
Flash
Words arrive at one fixed point, at 100–1,200 words a minute. Show one, two or three at once, with pauses at sentences and paragraphs.

Listen
Listen at 0.25–4× speed with each sentence highlighted. Playback continues with the screen off, remembers your place and supports a sleep timer.

Text
Read without running headers, page numbers or footnotes. Tap a sentence to start there. Uncertain words from scans are marked for checking.

Figures
Charts, diagrams and photos stay beside the text. Glance brings them into Flash as you reach them. Listen shows the current figure above the player and on the Lock Screen.

Try Flash
Press play and adjust the pace.
Every word lands on the same point, so your eyes stop moving and the words come to you. Longer words stay a little longer. A comma gets half a beat, and the end of a sentence gets a whole one. Try it slower, then faster, and find the pace where it still feels like reading. In the app, this is any document you give it.

Tempo Neural reads English and needs an iPhone or iPad with 6 GB of memory or more. On other devices, Listen reads with your Apple voices.

Landscape reading
Rotate your iPhone or iPad for a larger Flash stage, figures beside the words and controls that hide with a tap.

Your documents stay on your device.
All of it, on the device.
Lifting the text out, finding the figures, recognising photographs and the voices all happen on your iPhone or iPad. Nothing is uploaded.
No account.
Tempo never asks for your name, your email or a password. No analytics, no tracking, no advertising.
One request, when you ask.
The only time Tempo reaches the network is when you ask it to read a web page. It fetches that page and nothing else.
