Coach Sheet vs Trainerize: Honest Comparison and Pricing Math

TL;DR

Trainerize is the incumbent. It charges per-client tiers ($40 for 10 clients, $90 for 50, $180 for 100+), has a polished mobile app, and dominates Reddit mindshare. We’re newer and built specifically for coaches who don’t want their client history hostage to a subscription. If you’re scaling past 10 clients, the math shifts heavily in our favour. If your roster is small and you need a native app store presence, Trainerize might still be the fit.

Pricing math at typical roster sizes

Public Trainerize pricing fluctuates as they repackage. Numbers below are accurate as of May 2026, verified against their pricing page.

The crossover point is 1 client. You save from day one. The savings just compound as you scale.

Where Trainerize is genuinely better

We don’t pretend we’re the right call for every coach. Trainerize legitimately wins in a few places:

Native mobile apps in the app stores. Their iOS and Android apps have App Store reviews, ratings, search visibility. If your client expects to “download the app” before working with you, that pattern still has weight in 2026. Our client view is a Progressive Web App that feels native but lives at a URL, not in the app store.

Mature integrations. MyFitnessPal, Apple Health, Garmin, Strava, Fitbit. If your coaching relies on pulling automatic data from a wearable, Trainerize handles it. Coach Sheet doesn’t pull wearable data automatically; clients can paste numbers into a sheet column, but it’s manual.

Built-in payments. Trainerize includes Stripe Connect, so your client pays you through the same app where they get their workouts. That’s convenient if you don’t already have a payment flow. We don’t bundle payments; you keep your own Stripe (or whatever you use).

Brand recognition. Reddit has 14+ mentions of Trainerize in any given pricing thread. Clients have heard of it. Coach Sheet is brand new.

Larger exercise library out of the box. Trainerize ships 3,000+ exercise demonstrations. Ours has 200+ at launch and grows weekly, but the gap takes time to close.

Where Coach Sheet wins

Pricing model. Per-client tiers punish growth. Flat pricing doesn’t. We’ve kept pricing predictable specifically because the working trainers we interviewed kept describing Trainerize’s pricing as “the thing that pushes me to consider switching.” Direct quote from a Reddit thread we surveyed: “I hated the pay-per-client model. It just eats into your margins as you scale.”

Data ownership. This is the biggest one. Trainerize stores client history on their servers; if you cancel, that history is gone. Coach Sheet writes every workout, every measurement, every photo check-in to a folder in your Google Drive. The folder structure mirrors what working trainers already build manually (Bulgarian coach screenshot we studied has it: numbered folders, master template, per-client copies). Cancel us, the folder stays. Cancel Trainerize, the data is behind a paywall you no longer pay.

Visible formulas. TDEE shows as “BMR × Activity Multiplier (Mifflin-St Jeor + ACSM)”. RPE table is editable. e1RM uses Brzycki, with the formula in a hover tooltip. None of this is hidden in a black box.

Inline ‘Achieved’ comments. When a client logs “+2.5kg felt clean” or “rest pause last set”, the comment lives next to the exercise prescription, not in a separate chat tab. You read it Monday morning with the load already in context. Trainerize splits prescription and feedback into two tabs.

No AI generation. Trainerize ships a “generate workout with AI” button. We don’t. Whether that’s a feature or a bug depends on whether you trust your own programming more than a generative model’s. The trainers we interviewed unanimously trusted their own.

What’s the same

Both tools handle the basics: multi-week workout programs, exercise library with video, body measurement tracking, photo check-ins, habit tracking, mobile client view. The differences live in the surrounding workflow, not in the core feature checklist.

When to switch from Trainerize to Coach Sheet

Switch when:

• You have 10+ clients and the per-client tier just stepped up your bill
• A client cancellation reminded you that you don’t own the workout history
• You’re spending Sunday afternoons rebuilding next week’s programs from last week’s logs (we automate exactly that with Save Week)
• You want methodology configurability that Trainerize abstracts away

Don’t switch when:

• You’re under 5 clients and the $40 tier hasn’t bothered you
• Your clients explicitly want app-store-presence
• You rely on Trainerize’s wearable integrations
• You don’t want to use Google Drive

Migration plan

We’ve documented the migration path in our guide on switching platforms. Short version: export your client roster from Trainerize as a CSV, run the Coach Sheet onboarding wizard for each client (3 minutes per client), and you’re operational by the end of the day.
