The Problem

You became a trainer to coach people.
Not to be a spreadsheet jockey.

You spend Sunday night copy-pasting workouts into WhatsApp
Programs live in Google Sheets nobody opens
You have no idea if online clients actually trained this week
When a client asks "am I making progress?" you scramble for data
You lose 2-3 clients per quarter because they feel unsupported

Programs land on their phone automatically — they open the app and train
Every set, rep, and weight shows up on your dashboard in real time
Progress charts, PRs, and adherence data are always one click away
Automated nudges catch disengaged clients before they ghost
Your clients see a professional platform — not WhatsApp threads

How It Works

Two apps. One seamless system.

You coach from the Trainer Dashboard. Your clients train from the Workout App. Everything syncs in real time.

01

Build Programs

Use the visual program builder — or let AI generate one from a client profile. Import from Excel if you already have programs. Add exercises, supersets, coaching notes, and intensity targets.

02

Assign & Schedule

Assign programs to clients and map training days to their calendar. Schedule in-person or virtual sessions with recurring support and automatic reminders.

03

Clients Train, You Watch

Your client opens the app, sees today's workout with full guidance, and logs every set. You see everything on your dashboard as it happens. No asking. No chasing.

Client Workout App

The gym companion they'll actually use

Your clients open the app and instantly see today's workout. Every exercise has your coaching notes, target weights, and rest timers built in. They log as they go — you see results in real time.

✓ Full-screen workout mode with session timer and volume tracker
✓ Per-set logging: reps, weight, RPE, warmup toggle
✓ Previous session data visible for every exercise
✓ Coaching notes from trainer shown inline
✓ Superset grouping with color-coded indicators
✓ Automatic PR detection with confetti celebration
✓ Plate calculator for barbell exercises

Questions? We've got answers.

What exactly do my clients get?

Your clients get a free Progressive Web App (PWA) they install from their browser — no App Store needed. It works on both iOS and Android. They see today's workout, log every set in real time, track their progress with charts, message you directly, and view their schedule. It looks and feels like a native app.

Do my clients have to pay anything?

No. Your clients use Stackd completely free. You're the paying customer. Your subscription covers unlimited client access to the workout app.

What's a PWA? Will my clients know how to use it?

A Progressive Web App is a website that installs to your client's home screen like a regular app. They visit a link, tap "Add to Home Screen," and it's done. No App Store downloads, no updates to manage. It sends push notifications and works offline.

Can I import my existing programs from spreadsheets?

Yes (Pro plan and above). Drag and drop your Excel or CSV files into the program builder. Our smart matching system maps your exercises to the database automatically. You review, tweak if needed, and assign.

How does the AI program generator work?

Tell the AI your client's goals, experience level, available equipment, and training frequency. It generates a complete multi-week program with exercises, sets, reps, intensity targets, and rest periods. You can edit anything before assigning it. What used to take 1-2 hours takes 5 minutes.

What happens after my 14-day trial?

You choose a plan and add a payment method. If you don't, your account pauses — no charges, no data lost. You can reactivate anytime and pick up where you left off.

Can I switch plans later?

Yes. Upgrade or downgrade anytime from your dashboard. Changes take effect on your next billing cycle. If you upgrade mid-cycle, you're prorated.

Is my data secure?

Stackd uses enterprise-grade Row-Level Security, meaning trainers can only see their own clients' data, and clients can only see their own data. All connections are encrypted via HTTPS. We never share or sell your data.

Do you support gym owners with multiple trainers?

Yes. The gym owner dashboard lets studio owners manage multiple trainers, view aggregate analytics, transfer clients between trainers, and handle billing. Contact us for gym pricing details.

How do I get help?

Use the in-app messaging once you sign up, or email support. Pro and Business plans get priority response times.
