1FIT vs Assistant Coach: Fitness Coaching Software 2026

1FIT’s pricing page leads with £40/month. Read further and you find a £4-per-extra-client overage that quietly turns Basic into £120/month at 30 clients, well above the rate-card number. If you are evaluating 1FIT against Assistant Coach (a newer alternative we build, currently in public beta), the comparison that matters is not the headline price. It is what you actually pay at your roster size, what each platform can do, and whether you can ever leave with your client data.

Here is what this guide breaks down:

1. Real pricing at every roster size, with 1FIT’s per-client overage math made simple
2. A feature-by-feature comparison across 16 categories including AI, nutrition, check-ins, data export, and the coach-side workflow
3. Where each platform actually wins - strengths and gaps for both 1FIT and Assistant Coach
4. The data portability question and why 1FIT’s lock-in is unusual even among coaching platforms
5. A simple decision framework to match a platform to your coaching business

1FIT vs Assistant Coach: The 2026 Summary

Before the deep dive, here is the short version. Each platform optimizes for a different kind of coach.

What 1FIT Actually Costs in 2026

1FIT publishes pricing in GBP across four tiers, with a £4/client/month overage above each tier limit. There is no permanent free tier, only a 7-day trial. Here is the real cost at common roster sizes against Assistant Coach during beta.

The 1FIT tier ladder runs Basic £40 (10 clients), Growth £60 (adds 1FIT Pay, group chats), Scale £175 (75 clients, 2 team seats, Zapier), Enterprise £295 (£250 annual, unlimited clients). The cost-optimal tier flips around 44 clients (Basic → Scale) and 107 clients (Scale → Enterprise).

Beta pricing: Assistant Coach paid plans during beta start at £16.50/month (Starter, 100 AI credits/mo, billed annually) or £19.50/month if billed monthly. Pro is £29.50/mo annual / £34.50/mo monthly (500 AI credits). The free tier covers 15 clients (15 AI credits/mo). All paid plans during beta come with the first month free and lock in 50% off the post-beta list price for life (post-beta Starter is £33/mo annual or £39/mo monthly).

At 30 clients, a coach on 1FIT Basic pays £120/month vs £16.50 on Assistant Coach Starter - roughly £1,200/year, close to the revenue from one extra paying client. At 50 clients the gap widens to about £1,900/year. For the broader landscape, see our real cost breakdown across 10 platforms and the hidden fees buyers miss.

Feature-by-Feature: How 1FIT and Assistant Coach Compare

Price is only useful once you know what is included. Here is how the two platforms line up across the features a working online fitness coach or personal trainer actually uses.

Where Each Platform Actually Wins

Cost matters, but fit matters more.

Assistant Coach: the full coaching stack at a flat price

Strengths:

• Every core workflow built in at every tier including free: structured check-ins, meal plan builder, workout plan builder, structured goals, client notes and todos, coach website with lead capture, and full data export
• Workout logger with inline video review pinned to each set - no hunting through chat threads
• AI woven into the workflow: AI draft responses in your voice on every check-in, multi-month trend analysis per client, AI workout plan coverage analysis (body-region coverage, split balance, gaps, redundancy before you activate a plan), plus plug ChatGPT or Claude directly into your coaching data
• Branded client app your clients can install, plus branded meal plan and workout plan PDFs
• Flat pricing: free for 15 clients during beta, then from £16.50/mo (Starter, annual) for unlimited clients, Pro at £29.50/mo. First month free, 50% off post-beta list locked in for life
• Structured data export as a ZIP on every plan - no one-way door for workspace records

Gaps:

• No in-app messaging yet (email + check-in responses for now)
• No built-in payment collection yet (Stripe client-billing import is in beta)
• No wearables yet - no Apple Health, Garmin, Fitbit, Oura, or Google Fit (on the roadmap)
• Smaller exercise video library and newer brand with fewer third-party reviews than UK incumbents

1FIT: phased roadmaps and supplement plans with a UK accent

Strengths:

• Phased client roadmaps with milestones - clients see their training block broken into phases. Rare out of the box
• Supplement plans with dosage tracking built into the platform
• Integrated payments via 1FIT Pay (Stripe + GoCardless) from £60/mo Growth tier, plus 1:1 messaging on every tier and group chats from Growth
• Nutrition depth: rest-day vs training-day macros, MyFitnessPal sync with 3M+ foods, recipes from £60/mo Growth tier

Gaps:

• No AI features at all - no workout builder, no meal planner, no check-in analysis, no response drafting
• No self-service data export, no public API, and a Terms of Service that prohibits automated extraction (Section 8). Only path: GDPR DSAR to gdpr@1fit.com
• Per-client overage pricing (£4/client/mo above tier limits) makes the bill grow with your roster; no white-label app or full coach website builder
• Smaller exercise library (200+ videos) and limited wearables vs the broader market (Apple Health sleep only)

The Data Portability Question

Most coaches do not think about data export until they want to leave.

1FIT’s data export is among the most restrictive of any major coaching platform. No self-service export. No public API. Zapier gated to the £175 Scale tier with future-only triggers. A Terms of Service that explicitly prohibits automated data extraction (Section 8 bars systematic data retrieval, scrapers, spiders, and robots). The only documented path to retrieve your data is a GDPR data subject access request to gdpr@1fit.com, with no public format guarantee.

If you coach in the UK or EU, GDPR Article 20 entitles your clients to their personal data in a structured, machine-readable format, and the EU Data Act (applicable since September 2025) requires SaaS providers to actively remove switching barriers. Whether 1FIT’s current export approach satisfies these obligations is worth asking before you commit two years of client history to it. Our 10-platform data export audit covers this fully.

Assistant Coach exports structured workspace data (client profiles, check-in history, workout plans, meal plans, goals, notes, and body measurements) as a ZIP with JSON files and a client CSV on every plan including free, documented and tested.

Which Fitness Coaching Software Is Right for You?

A simple framework to decide:

• Choose Assistant Coach if you want every core workflow under one roof - structured check-ins, a workout logger with inline video review, meal and workout plan builders, goals, client notes, a coach website with lead capture, and full data export - at a flat price that does not move as your roster grows. AI is woven through the workflow (draft responses on every check-in, multi-month trend analysis, workout plan coverage analysis), but it is connective tissue, not the headline. Ideal for solo personal trainers and small teams working with 5 to 100+ fitness coaching clients.
• Choose 1FIT if phased client roadmaps with milestones are central to how you coach, you build supplement protocols as part of your service, you want one platform that bundles in-app messaging and payment processing on day one, and you are comfortable accepting the data lock-in trade-off in exchange for those features. Strongest fit if you are UK-based and want GBP billing without currency conversion friction.

If you are already on 1FIT and feeling the per-client overage at 30+ clients, the math in the first table above is probably enough to make the switch worth a Saturday’s effort. The beta lock-in pricing on Assistant Coach makes the move time-bounded - £16.50/month for unlimited clients only stays available for new signups while beta is still open.

Frequently Asked Questions

What is the difference between 1FIT and Assistant Coach?

1FIT is a UK-based all-in-one coaching platform with phased client roadmaps, supplement plans, integrated payments, and in-app messaging, priced from £40 to £295/month with a £4 per-client overage above tier limits. Assistant Coach is a full coaching stack - structured check-ins, workout logger with inline video review, meal and workout plan builders, goals, client notes, a coach website with lead capture, and structured data export, with AI woven through - priced as a free tier for 15 clients during beta and unlimited-client paid plans starting at £16.50/month. The biggest practical differences are pricing model (flat unlimited vs per-client overage), data export (structured workspace data vs no self-service export), and AI (Assistant Coach has it across the workflow, 1FIT does not).

How much does 1FIT cost per month?

1FIT has four paid tiers: Basic at £40/month (10 clients), Growth at £60/month (10 clients, adds payments and group chats), Scale at £175/month (75 clients, 2 team seats), and Enterprise at £295/month (£250/month if billed annually, unlimited clients). All tiers except Enterprise charge a £4/client/month overage above the included client limit. There is no permanent free tier - only a 7-day free trial.

Does 1FIT have AI features for fitness coaches?

No. As of April 2026, 1FIT does not market AI features anywhere on its platform or pricing pages. There is no AI workout builder, no AI meal planner, no AI check-in analysis, and no AI response drafting. By contrast, Assistant Coach offers AI draft responses written in your voice on every check-in, multi-month trend analysis per client, AI workout plan coverage analysis (body-region coverage, split balance, gaps, and redundancy on a saved plan before activation), and the ability to plug ChatGPT or Claude directly into your coaching data.

Can I export my client data from 1FIT?

Not in any meaningful self-service way. 1FIT does not document a data export feature, has no public API, and limits Zapier to the £175/month Scale tier with event-based triggers only (no historical data). Their Terms of Service (Section 8) explicitly prohibit automated data extraction. The only documented path to retrieve your data is a GDPR data subject access request to gdpr@1fit.com, with no published format guarantee. This is among the most restrictive data portability situations of any major coaching platform.

Is Assistant Coach cheaper than 1FIT?

Yes, materially. At 30 clients, 1FIT Basic costs £40 + 20 × £4 = £120/month, or you can move up to Scale at £175/month. Assistant Coach during beta is £16.50/month (Starter, billed annually) for unlimited clients - over £100/month less than 1FIT Basic with overage at 30 clients, which works out to roughly £1,200/year. The gap widens as your roster grows because Assistant Coach’s monthly cost does not move with client count.

Is 1FIT a good alternative to Trainerize?

1FIT is a credible Trainerize alternative for UK coaches who want a fresh interface, phased roadmaps, supplement plans, and a responsive small-team support experience. Multiple 1FIT testimonials describe coaches switching from Trainerize. The honest trade-offs to weigh: 1FIT has no AI, no self-service data export, no wearable integrations beyond limited Apple Health, and a smaller exercise video library. If those gaps matter, also evaluate Assistant Coach (AI plus structured export at a flat £16.50/month beta) or read our full TrueCoach vs Trainerize vs Assistant Coach comparison.

Does Assistant Coach have a free plan for personal trainers?

Yes. Assistant Coach has a free tier covering 15 clients during the current public beta with every coaching feature included - workout plans, meal plans, check-ins, AI check-in analysis (15 AI credits per month), goals, custom forms, a coach website with lead capture, and full data export. 1FIT has no free tier, only a 7-day free trial across all paid plans. For personal trainers starting out, Assistant Coach is the only one of the two you can run a real coaching operation on without paying first.

Pick the Platform That Matches How You Coach

The right platform fits how you coach today, scales without taxing you for it, and lets you leave with your data if next year does not go the way you expected. 1FIT is a thoughtful product with genuine UK strengths and a real pricing weakness above 15 clients. Assistant Coach makes the opposite trade: less in-app social and payment plumbing today, more depth across the coaching workflow (structured check-ins, workout logger with inline video review, meal and workout plan builders, goals, notes, lead capture, full data export) plus AI as a layer on top.

If you are starting out, Assistant Coach’s free tier (15 clients during beta) gives you enough runway to run a real fitness coaching operation before paying anything. If you are already paying for 1FIT and feeling the overage above 15 clients, the beta lock-in pricing on Assistant Coach is a time-bounded reason to move now rather than after.
