The Truly All-in-One Fitness Coaching Platform

Sound familiar?
If any of these feel familiar, you're not alone. SimplexCoach was built to fix all three.
"All-in-one" that isn't
Most platforms claim all-in-one, then go workout-first and leave nutrition and habits half-baked. So you're still back in DMs, Sheets, and PDFs for the parts they don't really cover.
Clients go quiet mid-program
Without real-time visibility into client check-ins, you only find out someone fell off the plan when they message asking to cancel. Reactive coaching doesn't get results.
No single source of truth
Habits in one app, macros in another, workouts somewhere else. With no unified view of a client, you only notice someone slipping when they message to cancel, far too late to act.
All-in-one that's actually all-in-one
Everyone says “all-in-one.” Most mean “workouts, plus a few extras bolted on.” In SimplexCoach, every pillar of coaching is native and equal, in one platform you and your clients can use on web and mobile alike.
The typical setup
- Habits tracked in DMs or a spreadsheet
- A separate app for nutrition and macros
- Workouts sent as PDFs or a third tool
- Progress photos buried in your camera roll
- Check-ins scattered across email and chat
Five logins, no single view, and the busywork lands on you.
One platform, everything native
- Habit tracking with streaks, synced with Apple Health & Health Connect
- Meal plans, macro targets & client food logging, fully native
- Workout builder with RPE/RIR & 1RM tracking
- Check-ins, custom forms, progress photos & body metrics
- AI review for form videos & meal photos, built in
One source of truth per client, so you act on what matters, fast.
Every pillar, equally serious
Built around how great coaches actually work, not how software companies think they work.
Know exactly where every client stands, before they drop off
Assign daily habits and tasks to each client and get a real-time feed of completions, streaks, and missed days. Habits are native here, not a bolted-on extra, so adherence is visible the moment it slips.
- Custom habit programs per client or from your template library
- Per-habit and overall streaks clients want to protect
- Steps, runs, and calories synced from Apple Health & Health Connect
Macro coaching without the back-and-forth
Build meal plans in minutes, set targets, and watch real adherence. Clients log meals in the same app they track everything else, so you never chase MyFitnessPal screenshots again.
- Meal builder plus QuickBuild shorthand to create meal plans in seconds
- Clients log assigned meals or add their own custom meals
- AI-assisted review of client meal photos, right in your queue
Programs with real training depth, and proof of results
Build workout programs with the depth serious coaches expect, while clients log every set in the app. Performance, body metrics, and progress photos chart automatically, right next to their habits and nutrition.
- Workout builder with sets, reps, rest, RPE/RIR, and 1RM tracking
- QuickBuild shorthand expands quick notes into a full program
- AI-assisted form video review: suggestions drafted, you approve
AI where coaching actually needs it
Not a chatbot bolted to the side. AI lives inside the review and plan-building workflows you run every day, and you stay in control of every word that reaches your client.
AI meal photo review
Meal photos land in your review queue with AI-drafted observations on portions and macro fit. Respond to a week of meals in minutes, not an evening.
QuickBuild
Type workouts and meals in quick shorthand and QuickBuild expands them into full structured plans, sets, reps, rest and macros included, ready to assign in seconds.
Smart plan suggestions
As you create or edit plans, SimplexCoach suggests sensible next steps: exercises, progressions, and meal tweaks. Building for ten clients feels like building for one.
Video and meal-photo review with AI suggestions: a workflow you won't find on the big coaching platforms.
One platform, the whole coaching workflow
No add-ons to buy, no extra apps to stitch together. Here's what's included.
Habit tracking & streaks
Daily habits and tasks with per-habit and overall streaks, plus a live completion feed.
Nutrition & food logging
Meal plans, macro and calorie targets, and in-app logging, including client custom meals.
Workout builder
Programs with sets, reps, rest, RPE/RIR, and 1RM tracking as clients train.
Body metrics
Weight, body fat, and measurements charted over time.
Progress photos
Side-by-side comparison views to make change undeniable.
Check-ins & feedback
Structured client check-ins so nothing slips through the cracks.
Forms & questionnaires
Intake and recurring forms to capture what you need to coach well.
Exercise video library
Attach exercise demos so clients always know the movement.
Reusable templates
Build a program or plan once, then reuse it across clients.
Coach dashboard & review
Every client at a glance, with a review queue for what needs you.
Apple Health & Health Connect
Steps, runs, and calories sync straight into habit tracking; workouts log back to Health.
Coach profile & discovery
Clients looking for a coach can find your profile and join you right in the app.
On the roadmap, shaped together with founding coaches:
Up and running in a day
No months-long onboarding. No dedicated IT team. Just better coaching, faster.
Create your workspace and invite clients
Set up your coaching workspace in minutes. Invite clients via email or a shareable link, they download the app and they're in. No IT required.
Build personalised programs in one place
Assign habit routines, set nutrition targets, and create workout plans per client, all in the same workspace. Build from scratch, reuse templates, or write in QuickBuild shorthand and get a structured plan in seconds.
Coach through one real-time view
A single dashboard shows every client's check-ins, habit streaks, macros, and workouts together, with AI-drafted feedback on form videos and meal photos waiting in your review queue. Reach out proactively when something changes, not reactively when they cancel.
“I built SimplexCoach because, as a coach, I couldn't find one platform that genuinely covered everything. Now we're building it the way coaches actually want it, together with our founding coaches.”
Ondrej, Founder of SimplexCoach
Join the founding cohort
We're hand-picking a small group of coaches for the beta launching summer 2026. Founding members get free access during the beta, a direct line to shape the roadmap, and founding-coach pricing locked in.
Frequently asked questions

We're targeting summer 2026 for the first beta cohort. Waitlist members get first access, typically within days of launch opening.
We're finalising pricing, but our plan is to offer a free tier that includes one active client, perfect for testing with a single client before committing. Paid plans will be per-coach per-month with no client limits at higher tiers. Everything in the platform is included, AI review and QuickBuild too; we don't plan to sell per-feature add-ons. We'll announce pricing to the waitlist before anyone else.
Primarily fitness coaches, personal trainers, and nutrition coaches who work with clients 1:1 or in small groups. If you're delivering personalised programs and need your clients to stay accountable between sessions, it's for you. It's built for the individual coach, not gym chains or franchises, so there's no enterprise bloat to wade through.
Genuinely all-in-one. Habits, nutrition and macros, workouts, body metrics, progress photos, and client check-ins are all native and equal in the same platform, not a workout app with a couple of extras bolted on. One platform on web and mobile for you and your clients, no spreadsheets or side apps to stitch together.
Four ways at launch: AI drafts technique feedback on client form videos for you to edit and approve; AI reviews client meal photos with observations on portions and macro fit; QuickBuild expands shorthand notes into structured workouts and meal plans in seconds; and smart suggestions help while you create or edit plans. You always stay in control: nothing reaches your client without your approval.
Both. Clients log the meals you've assigned with one tap, and they can also add their own custom meals when they eat off-plan. Barcode scanning and a richer food database experience are on the roadmap.
Not in the initial beta. A branded (white-label) client app is on our roadmap for after launch. At launch the apps carry SimplexCoach branding. Founding-cohort coaches will help us prioritise what comes next.
Yes, for everyone. SimplexCoach is cross-platform: coaches and clients can both use the native iOS and Android apps or the web app. Many coaches prefer the web dashboard for planning and reviews while clients live mostly on their phones, but every part of the platform works everywhere.
All data is stored in encrypted databases on secure cloud infrastructure. We follow best practices for General Data Protection Regulation (GDPR) and never sell client data to third parties.
CSV import for client lists is on the beta roadmap. Program templates can be built in-app and reused across clients, we're also planning to support importing from popular template formats in post-launch updates.
Absolutely, it's designed with online coaches in mind. Clients can be anywhere in the world. Everything is async-first so you're not tied to live sessions.
Yes. You can use just the nutrition and habit modules without enabling workout tracking. Each module is independently usable.
