Walk into your next interview calm, focused, and ready. Primo is a 2-5 minute guided routine designed to calm your nerves before any high-pressure moment. Whether you're preparing for a job interview, presentation, sales call, or difficult conversation, Primo helps you get out of your head and into the right mindset. No fluff. No meditation apps that take 20 minutes. Just a quick, effective routine you can do in the waiting room, your car, or anywhere you need it. — HOW IT WORKS — Tell Primo what you're preparing for and how much time you have. The app builds a personalized routine that combines: - Breathing techniques to activate your body's natural calming response - Body-based exercises to release tension you didn't know you were holding - Grounding techniques to get you out of your head and into the present - Mental reframes to turn nervous energy into focused energy - A backup plan so you know exactly what to do if something throws you off Each step is guided, timed, and research-backed. You just follow along. — WHY IT WORKS — Primo isn't based on generic advice like "just breathe" or "picture everyone in their underwear." Every technique in the app comes from peer-reviewed research: - The breathing pattern is based on Stanford research that found it calms your nervous system faster than traditional meditation - The anxiety reframe technique comes from Harvard research showing that saying "I am excited" before high-pressure moments actually improves performance - The backup plan feature is built on implementation intentions research, which found that having a pre-planned response makes you significantly more likely to stay calm under pressure We've taken the science and turned it into something you can actually use in the moments that matter. — FEATURES — Pre-Game Prep Your go-to routine before any high-pressure moment. Takes 2-5 minutes, depending on how much time you have. Personalized to your situation. Backup Plan Builder Create an "if-then" plan for when things go sideways. If you blank on a question, start to panic, or lose your train of thought, you'll have a pre-planned move ready. This is one of the most effective (and underused) techniques for managing performance anxiety. Daily Drills One-minute exercises that build your confidence over time. Practice reframes, breathing techniques, and mental skills so they become second nature. Small reps, big results. Today's Anchor Start each day with a grounding thought. A simple way to build a calmer baseline over time. — WHO IT'S FOR — Primo is for anyone who knows they're capable but struggles with nerves getting in the way: - Job seekers preparing for interviews - Professionals giving presentations or leading meetings - Salespeople before important calls - Anyone facing a difficult conversation - People who want to feel more confident in high-pressure situations If you've ever walked out of an interview thinking "I could have done so much better if I wasn't so nervous," Primo is for you. — WHAT YOU GET — - Guided routines personalized to your situation - Science-backed techniques that work in minutes - A backup plan for when things go wrong - Daily drills to build lasting confidence - No account required, your data stays on your device — SUBSCRIPTION OPTIONS — Primo offers a 7-day free trial with the yearly plan so you can experience the full app before committing.
