The fitness app for executives and entrepreneurs who want to stay fit without meal plans, restrictive diets, or 60-minute gym sessions they don't have time for.
Most fitness apps were built for people with time. You're not one of them. You run companies, close deals, fly weekly, eat with clients three nights a week. You've tried the meal plans. You've tried counting calories daily. You've tried pushing through 5AM workouts. Something always breaks first — usually your schedule.
You can't prep chicken and broccoli for the week when you have three client dinners, a flight to Berlin, and a board meeting. The plan collapses by Wednesday, and you're back where you started — except now you also feel like you failed.
Logging every bite, weighing every ingredient, checking macros before every meal. It works for people who have time to think about food. You don't. And the guilt spiral after one bad day is worse than the weight you're trying to lose.
You're in a hotel in Frankfurt with a treadmill from 2008 and 25 minutes before your first call. Or you're home at 10PM after a long day. The workout that's sitting in your app was designed for someone else's life.
Grip is built on a simple premise: if you're running a company, you already know how to plan, prioritize, and execute under constraints. You don't need to be motivated. You need a system that fits how you actually live — not how fitness apps think you should live.
Instead of daily meal plans, you get a weekly nutrition budget. Instead of fixed workouts, you get sessions that adapt to how much time you have, where you are, and what your week looks like. Instead of a drill sergeant, you get Jimmy — an AI coach who treats you like the adult you are.
We built Grip to do five things well, not twenty things badly.
Instead of counting calories daily and feeling guilty when a dinner runs over, you get two numbers per week: a protein floor (minimum) and a calorie ceiling (maximum). Everything within those boundaries is yours to spend however you want. Steakhouse dinner on Thursday? Tuesday adjusts. The week stays balanced.
Jimmy is the coaching intelligence inside Grip. He knows what you've eaten this week, what your goals are, how your travel schedule looks, and what's realistic for you today. Ask him anything: "I have a client dinner at Ruth's Chris tonight, what do I order?" He'll tell you. "I have 20 minutes and a hotel room." He'll give you a workout.
Three durations: 15, 25, or 40 minutes. Three settings: home, hotel, or gym. The app picks the right session based on your week — if you've had back-to-back meeting days, it won't hand you a 40-minute leg workout at 9PM. Progress tracking happens in the background. You just train.
Twenty pre-built protocols for the moments that usually break your diet: business dinners at steakhouses, sushi with clients, hotel breakfast buffets, long-haul flights, weddings, all-inclusive vacations, holiday season, stress-peak weeks. Open the playbook, read it in 90 seconds, walk into the situation knowing what to do.
Sunday evening. Two minutes. Three questions: weight, energy level, how the week went. That's it. The app adjusts next week based on your answers. No daily notifications reminding you to log food. No streaks to maintain. No guilt notifications if you skip a day.
We're direct about what we don't do. If any of these are dealbreakers, this isn't the right tool for you.
We're opening Grip to the first 200 members at a founding price. This is before public launch.
Join the waitlist and you'll hear from us when public access opens. No early-access pricing — you'll pay the regular €249/year.
Join Waitlist →Most fitness apps are built by fitness people for fitness people. They assume you want to think about food and training constantly. They assume the gym is a place you go. They assume restriction is a virtue.
Grip was designed differently. We built it around the constraints that actually define busy professionals' lives: calendars that don't flex, travel that doesn't stop, business dinners that aren't optional, and mental bandwidth that's already spent on other things. Every feature asks: does this respect the user's time, or consume more of it?
The nutrition math (Mifflin-St Jeor for metabolism, 1.8g/kg for protein) is the same used by qualified nutritionists worldwide. We didn't reinvent the science — we reinvented the interface.
The AI coach was built on a coaching framework authored by an active competitive-level coach with years of experience in body composition. The AI doesn't replace the expertise — it scales it.
Hard minimums on calorie targets. Automatic flags on eating disorder signals. Immediate referral protocols for medical or mental health concerns. We don't optimize for engagement at the cost of user welfare.
Most apps optimize for daily engagement — streaks, notifications, constant logging. Grip optimizes for weekly consistency. Most apps assume you want to think about food all day. Grip assumes you don't. The difference shows up in whether you're still using it six months from now.
Yes. The weekly budget model doesn't require daily granular tracking. You log meals at a rough level (describe what you ate, the AI estimates), and the system tracks the weekly total. You check in once on Sunday. If your weekly numbers are off, we adjust together.
This is specifically who we built it for. The situation playbooks cover airport layovers, hotel breakfasts, hotels without gyms, and international dinners. The AI coach adjusts plans in travel mode automatically. Your 25-minute hotel bodyweight session is as valid as a gym day.
Most apps fail at the edges: business dinners, travel, stress weeks, social events. Grip is designed around those edges, not the idealized center. If you've given up on other apps because real life kept getting in the way, that's the exact reason this one is built how it is.
The AI coach will flag situations where our general advice should be checked with your doctor. We don't replace medical professionals — we work alongside them. If you have diabetes, thyroid issues, take antidepressants, or have other conditions, you'll get a version of the coaching that acknowledges those contexts.
Hard safety limits are built into the system: calorie floors, weight-loss rate caps, automatic referrals for injury, eating disorder signals, and crisis language. The AI operates within a tight framework — it won't recommend dangerous deficits, won't diagnose injuries, won't bend rules even if you ask it to.
Your profile stays private to you and the Grip system. We don't sell data. We don't share with third parties beyond what's needed to run the app. Full privacy policy and data handling details will be published at launch — we comply with GDPR/AVG.
Early access opens to founding members now. Full public launch is planned later this year. Founding members get access during the beta period and permanent access thereafter.
30-day refund, no questions asked. We'd rather you leave than stay frustrated.
No. Founding members pay once at €149 and keep lifetime access. No renewals, no cancellation needed. Not happy within 30 days? Full refund, no questions asked.
If you've read this far, you're probably the right fit. Grip isn't for everyone — it's for people who want to stay lean without making fitness their personality. Who want a coach, not a cheerleader. Who value their time more than they value extra features.
