The last fitness app. Whoever you are. VTC was built for you. Most fitness apps are built for one thing. Voltage Training Club is built for the solo athlete grinding through their training and tracking macros and progress, the client working with a coach, and the trainer building a business around the results they deliver. One platform. Three powerful experiences. Training solo? Stop piecing together spreadsheets, notes apps, and three different apps. VTC gives you a proper training tool. 
Log your workouts from a full exercise library, track every set, rep, load and RPE with a built in rest timer, switch between kg and lb on the fly, and use the plate calculator to work out your barbell loads. 
 Search commercial gym machines by brand and model, not just "chest press." Your nutrition gets the same treatment. Scan a barcode and we'll log the food for you, or snap a photo of the nutrition label if there's no barcode to scan. 
Track calories, protein, carbs and fat against your goals, with water tracking sitting right alongside. Our nutrition database covers fast food and takeaway, including large chains, and you can save your own foods, recipes and meal plans too. Heading out for a run? Track outdoor walks, runs and hikes with GPS, including in the background, so your session keeps going even if you leave the app. On iPhone, follow your live run from the Lock Screen or Dynamic Island. Treadmill runs and daily steps in sync. Your training, tracked the way it deserves to be. Looking for your perfect coach? Find a trainer who actually fits your goals, in person or online. Not just whoever comes up first in a search on social media. Browse coaches by specialty, read real reviews, and connect with someone who trains people like you. Strength. Bodybuilding. Physique. General fitness. Book sessions, follow their programming, and stay in contact through built in messaging. Want to find a gym while you're at it? 
 Search by country and city, see photos, amenities and contact details, and connect with the people training there. Everything in one place. Simple. Running a coaching business? Your clients deserve better than PDFs and communication spread across seven different platforms. VTC gives you the tools to run a professional business. 
Create and assign programs, manage bookings, communicate with clients, and build a profile that grows your reach. Spend less time on admin. More time coaching. Why VTC beats the alternatives. The fitness app market is full of trackers that can't connect you to a coach, coaching platforms that can't track workouts, and booking tools that can't do either. 
VTC is the first platform that does all of it, properly. No workarounds. No juggling seven different apps. Just one platform built around how fitness and coaching actually works. Once you're logging progress, sharing it is easy too. Turn a workout, run or step count into a branded share card, ready for Instagram Stories. All of that. For Free.
