What it counts
The figures on these cards are a sample, for illustration.
FILLERS · 11 · “um” ×6, “like” ×3
Fillers and hedges
Counted from your speech on the phone. The transcript is thrown away after counting. Only the counts and their times are kept.
PAUSES · 4 over 1.5 s
Pauses
The silences that land, and the ones that stall, placed on the timeline of the take.
HANDS · in frame 82% of the take
Your hands
Where they are and how much they move, when the framing can see them. When it cannot, Crest says so.
What it will never do
- Guess how you felt
- Score your health or personality
- Judge what you said
- Recognise who anyone is
- Fill a gap it could not measure
Your best is already on tape.
Every rehearsal finds the eight seconds where you looked away least. Watch it, keep it, and share it if you want to. Crest measures your ceiling, not your floor, so practice has something to aim at.
- Investor pitch
- Job interview
- Keynote opening
- Sales call
- Difficult conversation

Questions
Does my video get uploaded anywhere?
No. Every take is recorded and read on your iPhone, and the video, audio and face and body points stay there. Your account keeps your profile and your results (the counts and their times) so your progress follows you to a new phone.
What exactly does it measure?
When you look away compared with when you start a sentence, filler words and hedges, pauses, and where your hands are. Every instance is timestamped so you can replay it.
Does it tell me how I felt, or how I came across?
No. Crest counts behaviour. It never infers emotions, health or personality, and it never judges what you said. When something could not be measured, it tells you instead of guessing.
What do I get for free?
Your first full result is free, then three more reads, then one read a week, for as long as you like.
What does Crest Pro add, and what does it cost?
Unlimited reads and your patterns across takes. US$14.99 a month or US$109.99 a year, billed by Apple. Eligible Apple Accounts get 3 days free, then it renews automatically. Cancel any time in your Apple Account settings.
Why do I need an account?
So your history and patterns are never lost. Sign up takes about 30 seconds with Sign in with Apple or your email, and two quick questions so Crest can tune your drills. You can delete your account and its data from Settings at any time. Marketing emails are opt-in and you can stop them any time.
Which iPhones does it run on?
Crest is built for iPhone on iOS 26 and later. Prop the phone at eye level, or hold it, and you are set.
