Crest - Ride Out Cravings
Urge surfing for any habit
Only for iPhone

Giving in now gets logged instead of ignored, proof in your own numbers that urges fade, and an optional heads-up right before your usual window.
Every urge rises, peaks, and fades — just like a wave. Crest helps you ride through cravings instead of giving in.
WHAT IS URGE SURFING?
Urge surfing is a proven technique from therapy (DBT). The key insight: most urges peak within 10-20 minutes, then naturally fade. Most people give in during the rise, never learning that urges pass on their own. Crest gives you a calm, beautiful place to ride out that wave.
HOW IT WORKS
Tap Surf Now when an urge hits. Watch your wave rise, crest, and fall in real time. Gentle haptics guide you through each phase. Reach for a coping tool if you need one. Log it when it passes.
PROOF THAT URGES ACTUALLY PASS
Log how strong an urge was at its worst and how strong it was by the end, and Crest turns those into evidence: how far your urges actually drop, how long it takes, and how many times you've now proven it to yourself.
SLIP-UPS ARE DATA, NOT FAILURES
Gave in? Log it. Nothing breaks and no score drops. Crest asks what set it off, because the triggers that beat you are the most useful thing it can learn about you — and you'll see them separately from the ones you ride out.
FEATURES
◆ Wave visualization that follows your urge's journey
◆ Four phases: Rise → Crest → Fall → Calm
◆ 8 coping tools: breathe, ground, affirm, journal, body scan, cold, move, delay
◆ Countdown or count-up timer — your choice
◆ Streaks, totals, and time spent riding urges out
◆ Patterns: when urges hit you, and what triggers them
◆ An optional heads-up shortly before your usual window
◆ Home Screen and Lock Screen widgets, Live Activity, and Siri
◆ Private iCloud sync across your devices
PRIVACY FIRST
No account, ever. No analytics, no tracking, no ads, and no servers of ours. Your surfs sync through your own private iCloud, which we can't read. Your journey is yours alone.
WORKS FOR
Food cravings, doom scrolling, shopping impulses, nail biting, vaping, procrastination.
Any urge you want to outlast.

Built with care. You've got this.
Slip ups are data, not failures — and now Crest treats them that way.
GIVING IN GETS A SCREEN
Before, giving in dropped you back to the home screen with nothing recorded. Now it's a moment: how long you rode it, what set it off, how strong it was. No judgement, no lecture, no number going down. Knowing the pattern is how you beat it next time.
SEE YOUR URGES FADE
Crest already asked how strong an urge was at its worst and by the end. Now those numbers add up to something: "It passed 47 of your 50 surfs — hit you at 7, you left it at 3." Proof that urges pass, in your own data.
WHAT BEATS YOU
Your triggers are now split in two: the ones you ride out, and the ones that win. The second list is the useful one.
A HEADS-UP BEFORE YOUR WINDOW
Optional. Once Crest can see a real pattern in when your urges hit, it'll nudge you about fifteen minutes beforehand — so you can get ahead of it instead of reacting to it. Worked out entirely on your device.
SIMPLER
Insights and Progress were two names for the same screen. They're one now. Home leads with Surf Now, with your proof right underneath. Tap any past surf to open it.
