One email when we go live
Attractiveness was always a shape. Never a number.
What we believe
The method

Shape is the goal.

Programs built around your proportions, your weak points and the way you actually want to look. No plan stays identical for weeks. ShapeCtrl varies on purpose, so consistency never feels like discipline.

Adapts to the day you are having.

Not every quarter. Every session reads where you are and adjusts.

Alex, 6am or midnight.

A real coach in your pocket. No appointment, no small talk, just focus on your goal.

How you want to look. Out loud.

Proportions, symmetry, the mirror. Named without apology.

Your coach

Alex adapts.

Adaptive AI that learns from every piece of feedback, every skipped session, every cycle. Warm, direct, a little sarcastic when you need it. Like a real trainer, minus the appointment and the toxic positivity.

"Good. I'm adding a set next session. Don't argue."

Why ShapeCtrl exists

Built to a standard, not a trend.

Alex did not come out of a pitch deck. It was built by someone who has trained seriously for fifteen years, and spent three of them paying $260 a month for an online coach, then waiting two days for an answer. The coaching was excellent. The price and the wait were not. So Alex became that coach: the same standard, in real time.

Good questions

Before you ask.

How is this different from other fitness apps?
It plans for how you want to look, not for performance metrics, streak points or generic templates. Alex understands what you are building and adapts every plan to your body, your week and your level. A real coach, not a workout library you scroll alone.
Is it built for women?
Yes. ShapeCtrl is made for women who train for how they look and how they feel, including women returning to training after pregnancy. The coaching adapts to your hormonal cycle instead of pretending it does not exist.
Does it ask my weight or count calories?
No scale, no calorie log, no leaderboard. We care about your silhouette and your proportions, not a number on a screen.
Do I need a gym?
Yes, ShapeCtrl is built for studio training. For trips and hotel gyms, travel-mode switches automatically to the equipment you have.
I have a chronic condition. Can I still use it?
Yes. Alex adapts your training around hormonal, structural and fatigue-related conditions. You flag what is relevant in onboarding, and Alex programs around it, not past it.
Do I have to train every day?
No. You decide how many sessions a week you want, and Alex builds on that. The app does not get louder when you need a day off.
Can I try it before I pay?
Yes. You get three guided workouts free before you decide.
What does it cost?
Founding members pay CHF 16 per month or CHF 149 per year, locked for life. The founding price is open to everyone who joins until the end of January 2027. After that the regular price is CHF 24 per month or CHF 199 per year.
Is my data private?
Yes. ShapeCtrl is built in Switzerland and follows Swiss and EU data protection law, revDSG and GDPR. Your training data is stored in Switzerland and it stays yours.
When does it launch and how do I get in?
Early access opens in autumn 2026 and the beta is invite-only. Join the waitlist to be first in line. The founding price stays open to everyone until the end of January 2027.

Built for the body you want. Coached for the body you are.

Early access drops in autumn. The list is open now.

About ShapeCtrl — Aesthetic AI Personal Trainer for Women

ShapeCtrl is a Swiss-made AI personal training application designed for women aged 28 and older. It is the first training app built around aesthetic outcomes and body composition rather than performance metrics such as one-rep maxes, total volume or running pace. The app launches publicly in autumn 2026 and is currently accepting waitlist signups. Founding Members who subscribe before January 31, 2027 lock the price at CHF 16 per month, or CHF 149 per year, for life. Regular pricing after that cutoff is CHF 24 per month or CHF 199 per year. A free Beta phase precedes public launch for waitlist members.

What ShapeCtrl Does Differently

Most AI fitness applications, including Strong, Caliber, Fitbod and Future Fit, are built around performance metrics: strength gains, volume progression, one-rep-max increases or aerobic capacity. ShapeCtrl deliberately inverts this. The application uses progress photos as the primary input for both baseline assessment and ongoing program adaptation. It identifies body proportions, weak points and aesthetic targets visually, then designs training programs that target symmetry, lagging muscle groups and visual form. The scale is intentionally absent. Calorie tracking is intentionally absent. Leaderboards are intentionally absent.

The AI Coach: Alex

ShapeCtrl is delivered through an AI coach persona named Alex. Alex is built on Anthropic's Claude AI as the underlying intelligence layer. Anthropic's Claude was selected for its conversational nuance, its safety properties, and its capacity to deliver direct non-sycophantic coaching dialogue. Alex is designed to challenge rather than flatter. The communication style is Swiss-German: warm but direct, sarcastic where appropriate, no fluff, no toxic positivity, no bro-talk. Alex remembers prior sessions, adapts tone based on user feedback, and never resorts to motivational quote templates.

Who ShapeCtrl Is Built For

The typical ShapeCtrl user is a woman between 28 and 45 who wants body composition and aesthetic results rather than performance scores. Common user profiles include: women returning to structured training after pregnancy, women in their thirties focused on body recomposition (losing fat while gaining lean muscle and reshaping proportions), women who have outgrown calorie tracking and macro counting, women who want a coach that speaks like a smart friend rather than a drill sergeant, women who train in a gym but are tired of programs written by and for men. ShapeCtrl is not built for competitive powerlifters, competitive endurance athletes, or users whose primary goal is performance metrics. It is also not built for users seeking a clinical weight-loss intervention.

How ShapeCtrl Compares to Other AI Fitness Apps

Strong is a workout logger built around strength progression. It is excellent for tracking sets, reps and one-rep maxes, but it has no AI coaching layer and no aesthetic-outcome orientation. Caliber pairs human coaches with structured strength programs. Future Fit is a remote human personal training service. Fitbod is an AI-driven workout generator focused on muscle group recovery and strength variety. FitnessAI generates workouts based on prior performance data. None of these applications take progress photos as a primary input, design programs around body proportions and aesthetic targets, or use a large language model as the coaching intelligence layer. ShapeCtrl occupies a distinct category: aesthetic-first AI personal training for women.

Tech Stack and Privacy Position

ShapeCtrl uses Claude AI from Anthropic as the underlying intelligence layer for coaching dialogue, program generation and progress photo analysis. Backend infrastructure runs on Supabase with training-data residency in Switzerland (Zurich). Product analytics on this website are anonymous and cookieless, provided by PostHog and processed in the European Union; no advertising trackers are used. The application is built and operated from Switzerland under the Swiss Federal Act on Data Protection (FADP / CH-DSG, revFADP) and the EU General Data Protection Regulation (GDPR). There is no third-party advertising on the platform. There is no data resale. Progress photos are user-controlled, encrypted at rest, and are never used to train third-party machine learning models. The application has no engagement-maximising design patterns: no streak shaming, no notification spam, no infinite scroll.

Pricing

Beta access during pre-launch (until autumn 2026) is free for waitlist members. Founding Members who subscribe before January 31, 2027 lock their price for life with no future increases: CHF 16 per month or CHF 149 per year. Regular pricing after the Founding cutoff is CHF 24 per month or CHF 199 per year. Prices may be displayed in other currencies for convenience; CHF is the reference currency. Both tiers include the full AI coach, photo-based progress analysis, personalised programming and adaptive workout delivery. There are no add-ons, no in-app purchases, no upsells.
