personal trainers and fitness coaches
Personal trainers and fitness coaches run their businesses on a patchwork of tools they openly resent: Trainerize and TrueCoach for delivery, MyFitnessPal for nutrition, plus spreadsheets and Notes apps to fill the gaps. The complaints cluster around the same wounds: workout-logging apps that crash or lose reps mid-session because there's no gym Wi-Fi, hours of unpaid evening work hand-building programs and macro targets, exercise video libraries that are incomplete or look like they were filmed in 2011, and platform pricing that quietly climbs per active client until a growing roster becomes a punishing tax. Every one of these is a recurring, revenue-leaking annoyance for a coach who only makes money when they're coaching, not fighting software.
The research desk scanned Reddit, Hacker News, and independent forums. 5 opportunities made the cut — 9 sources reviewed — medium confidence.
1. RepProof — crash-proof, offline-first in-session workout logger
7.2A dead-simple iOS/Android app for trainers to log sets, reps, and weights live during a session that works offline and NEVER loses data. It solves the single most enraging complaint across every major platform: logging a full workout during a session and having the app crash or fail to save it. Positioned as a lightweight companion (not a full CRM) that syncs to the big platforms, so trainers keep their existing tools but stop losing session data.
Frank L. (Personal Trainer) on ABC Trainerize: 'There is nothing worse than logging a whole workout during a session with a client, and then the app won't save it.' Ariel J. (Personal Trainer): 'Sometimes when I add a client workout or body Stat it will also add to other client profiles. It crashes often.' TrueCoach's Anthony R. (Personal Trainer): 'The for coaches app needs to actually be usable please, you are forced to use the browser.'
First move: Build an offline-first PWA/mobile MVP that logs sets locally and syncs on reconnect, then validate by posting a free beta in r/personaltraining and the Capterra review comment threads where these complaints live.
2. CoachAI — AI program + meal-plan generator that exports to Trainerize/TrueCoach
6.8An AI tool that takes a client's goals, injury history, and available equipment and drafts a full periodized training block plus a macro-based meal plan in seconds, which the trainer edits and approves. It directly answers the white-space complaint that the dominant platforms have no AI program generation, and that writing programs and meal plans by hand eats hours per client. Exports as a CSV/PDF or pushes into the platform the coach already pays for.
Ivan F. (CEO) reviewing ABC Trainerize lists as a con: 'No ai Option to create workouts and meal plans.' Industry coverage notes most trainers 'settle for selling cheap programs' partly because program/meal-plan creation is so time-consuming, and that newer entrants like CatalysFit are forming specifically around 'AI reading each client's real data and generating personalized workout programs that the trainer reviews, edits, and approves.'
First move: Ship a single-page tool that takes a structured intake and outputs an editable 4-week block + meal plan, charge per-seat monthly, and seed it to trainers complaining about manual programming and the missing AI feature.
3. FitCostCheck — fitness coaching software pricing comparison + alternatives directory
7.0A content/affiliate site that does for coaching software what NerdWallet does for credit cards: transparent, regularly-updated breakdowns of true all-in cost (per-client tier jumps, payment processing %, nutrition add-on fees) for Trainerize, TrueCoach, Everfit, My PT Hub, etc., plus a 'find a cheaper alternative for my client count' tool. Monetized via affiliate referrals to the platforms and cheaper challengers, all of which run partner programs.
Documented hidden-fee anger: TrueCoach 'charges $26/month for 5 clients, $58 for 20, and $137 for 50' with '5% on every payment' (~$3,600/yr for a $6k/mo coach), and Trainerize meal planning is an extra '$45/month.' Trainerize's July 2024 and 2026 price increases (now $22–$250/mo) drove a wave of 'reasons coaches leave' and 'better alternatives' searches. Capterra reviewer Sarah M. (Owner) flags pricing as 'high for new trainers.'
First move: Build 10-15 SEO pages targeting '[platform] pricing 2026', '[platform] alternatives', and 'cheapest personal training software for X clients', with an interactive cost calculator, and apply to each vendor's affiliate program.
4. DemoVault — modern, complete exercise demo video library + embed API
6.4A licensable library of high-quality, modern exercise demonstration videos (multiple angles, every modality, not CrossFit-skewed) that trainers can drop into client programs or embed via a simple link/API. It targets the most universal feature complaint: every major platform's built-in exercise library is limited, outdated, low-quality, or biased toward one training style. Sell as a flat monthly subscription with white-label embeds.
Craig H. (Fitness Coach) on TrueCoach: exercise library 'could do with updating and have a wider variety of exercises,' noting it is 'overly CrossFit-oriented.' Michał K. (Personal Trainer): 'Poor video quality in the exercise library.' On Trainerize, Amy M. (Owner): 'The videos quite outdated for the exercise demos.' On My PT Hub, Poppy H. (Coach): 'the standard exercise library was fairly limited,' and Sarah M. (Owner): 'The exercise library doesn't have all the exercises I was looking for.'
First move: Film or license 200-300 clean multi-angle exercise clips, gate them behind a subscription with shareable embed links, and pitch directly to coaches who complain about library gaps on G2/Capterra.
5. MacroBridge — reliable nutrition sync + automatic macro averaging for coaches
6.1A lightweight tool that pulls each client's daily food log (MyFitnessPal and others) and automatically computes weekly macro averages and adherence, replacing the broken/manual sync coaches deal with today. It directly fixes the recurring complaint that MyFitnessPal integration is unreliable and that trainers must open each client's log and average macros by hand. Sells as a per-coach monthly add-on dashboard.
Maegan H. (Owner) on Trainerize: 'The issues with MyFitnessPal syncing over is constantly a pain... ongoing issue,' and 'I have to individually go into each person['s] MFP and calculate averages myself.' Nancy G. (Personal Trainer/Nutrition Coach): 'Syncing with MyFitnessPal wasn't very smooth and could definitely be improved.' Emma B. (Manager) on My PT Hub: 'No way for clients to log just macros every day.'
First move: Prototype an integration that ingests client food logs and outputs a weekly macro-average + adherence dashboard, and validate against the nutrition-coach segment complaining about manual averaging on Capterra.

What software do personal trainers and fitness coaches use?
Most coaches deliver programs through dedicated platforms like Trainerize, TrueCoach, Everfit, or PT Distinction, and lean on MyFitnessPal or Cronometer for client nutrition tracking. Many supplement these with spreadsheets, Google Docs, and messaging apps to handle the parts the main platform does poorly, such as custom program logic or macro math. The constant friction is that no single tool does everything well, so coaches stitch together three or four subscriptions and still do manual work to connect them.
What are the biggest problems personal trainers and fitness coaches face with their software?
The loudest complaints are workout loggers that crash or fail offline in gyms with no signal, costing clients their in-session data, and the hours of unpaid time spent manually building programs and meal plans from scratch. Coaches also gripe about exercise video libraries that are incomplete or dated, unreliable nutrition syncing between apps, and per-client pricing that balloons as their roster grows. Each of these turns billable coaching time into administrative busywork or pushes margins down as the business scales.
Is there a tool that builds workout programs and meal plans automatically for coaches?
This is one of the most requested capabilities, because hand-writing periodized programs and calculating per-client macros is the single biggest time sink in the job. AI program and meal-plan generators that can produce a draft a coach edits, rather than writes from zero, can cut hours per client each week. The highest-value versions export cleanly into platforms coaches already use like Trainerize or TrueCoach, so the AI handles the drafting and the coach keeps their existing delivery workflow.
Why do fitness coaching apps lose workout data during sessions?
Most gym floors have weak or no cellular and Wi-Fi coverage, and many logging apps are built cloud-first, so a dropped connection mid-set can fail to save reps, weights, or whole sessions. Coaches and clients then have to reconstruct numbers from memory, which undermines trust and the training data that progress depends on. An offline-first logger that stores everything locally and syncs later when a connection returns directly solves the most damaging reliability complaint in the niche.
How do personal trainers and fitness coaches make more money?
The fastest gains usually come from reclaiming unbilled time rather than adding clients: automating program and meal-plan creation, eliminating manual macro averaging, and cutting the admin glue work between disconnected apps. The second lever is controlling software cost, since per-active-client pricing on the major platforms eats margin as a roster grows, making it worth comparing alternatives and switching when the math turns. Coaches who reduce per-client overhead can take on more clients without their workload or tooling bill scaling at the same rate.
