For gyms, personal trainers and members

Training that adjusts to the person doing it.

Ironlark starts with a health screen and a short assessment, recommends a programme, then changes the reps and weights from what each person actually logs. Coaches get the calendar, messages, groups and reports to run it all in one place.

Pilot places are open to gyms, coaches and individual members in the UK.

A week with Ironlark, in under a minute.

Stronger over time

Progress you can see, week after week.

Every logged set feeds the next session, so the plan keeps pace with the person following it, whether that is a first-week member or a runner building toward race day.

Who it is for

One app, three ways to use it.

Gyms offer it to members, coaches run their clients on it, and anyone can use it on their own.

Gyms

Give every new member a proper start and a plan that keeps pace with them.

  • Onboarding assessment that turns goals and fitness level into a recommended programme
  • Programmes built from templates you, or the coaches you choose, approve
  • Groups and squads side by side, with group sessions and attendance
  • Challenges, streaks and milestones that keep members coming back
  • Progress reports with your logo, saved as a PDF
  • An Insights dashboard: active members, sessions, and how each coach's clients are doing
  • QR codes on your machines, so members scan and log straight from the gym floor
  • Bring your existing members across from a spreadsheet

Ironlark sits alongside your booking, access and billing systems. It does not replace them.

Personal trainers

Spend your time coaching, not rebuilding spreadsheets every week.

  • A home screen with today's sessions, who's behind this week and new records worth a message
  • Programme builder with rounds, supersets, warm-ups and cardio, sized to the session you've booked
  • A "needs attention" list: pain, low readiness, load spikes, missed sessions and stalled lifts
  • Weight and rep suggestions from every logged set, which you can override
  • A calendar with working hours and time off. Book a session and your client gets a calendar invite, or let clients book your free time themselves
  • Messages, check-ins and private coach notes, and one tap to congratulate a client on a new record
  • Your photo and profile, so clients get to know you
  • Client details in one place: contact details, emergency contacts and medical notes, and a client list you can download. Import your existing clients from a spreadsheet

Payments for coaching are planned for a later release.

Members

Know what to lift today and why, whether or not you have a coach.

  • Health screen and starting assessment
  • Recommended programme for your goal, kit and available days
  • Workout player with form cues and demo video links, that works with no signal, and on Apple Watch
  • A weekly plan that works around matches, exams and busy days, with reminders
  • Left and right tracked separately on single-arm and single-leg exercises
  • A summary of today's records after every workout, compared with last time
  • Progress charts, strength records, streaks and a check-in every six weeks, in kg or lb
  • Book sessions with your coach from their free times

Features

Everything a coach and their clients need, in one app.

Built for the gym floor: big buttons, one tap per set, and nothing lost when the signal drops. It works on any phone, tablet or computer, and there's an iPhone and iPad app.

Workout player

Sets, rest timers and timed holds, one tap at a time. It works with no signal and saves everything as soon as it's back.

Apple Watch

Follow the workout and log each set from your wrist, with rest and hold countdowns. Workouts save to Apple Health with heart rate and calories.

Cardio, jumps and throws

Rowing machine, SkiErg, treadmill and bikes done to a time, a distance or calories. Jumps and throws record the best distance, and single-leg hop tests compare left and right.

Sessions that fit the booking

Set a session length and a warm-up. The builder tells you if a workout won't fit, and stretches the rests to fill it when it's short. People training alone say how long they've got.

Train together, live

A PT logs the session on a tablet and the client's phone updates as it happens, set by set.

Progression that explains itself

Every logged set shapes the next session's weights and reps, with the reason shown. Under-18s get smaller jumps and coach approval.

A pain check, not just a button

Tap "It hurt" for a few quick questions: carry on lighter, skip the exercise or stop. The coach is told, straight away if it's serious.

Readiness and training load

A ten-second check before each session, and a warning when someone's training load jumps well above their usual week.

Calendar and bookings

Set your hours and time off, book sessions from free time, or let clients book themselves within your rules. Everyone gets a calendar invite with reminders. See when your week is filling up and when you have room for new clients.

Messages and check-ins

Chat with clients, send quick check-ins about training, sleep and stress, and get an email when something needs you.

Progress and reports

Trend charts, estimated strength records with no max testing, a summary of today's records after every workout, body measurements, check-in results, and progress reports saved as a PDF.

Left and right

Single-arm and single-leg exercises log each side's own weight and reps, and each side progresses at its own pace. Handy when one side is coming back from an injury.

Gym floor and QR codes

Stick a code on each machine. Members scan as they go, see what they did last time and what to aim for, and link supersets with set rounds.

Groups, challenges and streaks

Squads side by side, group sessions with attendance, challenges with privacy-safe leaderboards, and weekly streaks that never punish a rest day.

Client details

Contact details, emergency contacts and medical notes, one tap away during a session. Clients keep their own details up to date, and you can download your client list.

Phone, tablet or computer

One app for the whole team: a side menu on a tablet or laptop, a bottom menu on a phone. Get it from the App Store on iPhone and iPad, or add it to the home screen on Android.

Help built in

A quick start guide and a welcome email for everyone who joins, getting-started checklists that tick themselves off, and short how-to guides a tap away in the app.

How it works

From first login to the next heavier set.

The same five steps for a gym member, a coached client or someone training alone.

  1. Screen

    A short health questionnaire comes first. If an answer needs a professional opinion, Ironlark pauses and points to a GP or coach before any plan is made.

  2. Assess

    Goals, training history, injuries, kit, available days and a few simple baseline tests.

  3. Recommend

    A starting programme chosen from approved templates, with the reasons shown. A coach can swap it.

  4. Train and log

    A workout player records every set, with an optional effort rating, and a quick readiness check before the session.

  5. Adjust

    The next session reflects the last one. Every few weeks a re-assessment checks the plan still fits the person.

Progression

Simple rules first, effort ratings once they help.

Suggestions come from clear rules you can read and a coach can overrule. Nothing is a black box.

Reps first

Each exercise has a rep range, for example 8 to 12. Reach the top of the range on every set and the weight goes up. Fall short and the weight stays while you build reps.

Effort ratings come in after a few weeks

New lifters begin on reps alone. Once they are comfortable judging how many reps they had left, effort ratings (RPE and reps in reserve) refine the suggestion, so a set that was a grind does not trigger an increase.

Extra care for young athletes

Under-18s get smaller jumps, no one-rep-max testing and coach approval for changes.

Privacy and security

Health data that stays where it belongs.

Training and health records are some of the most personal data there is. Ironlark is built for UK data protection law from the start, including the ICO Children's Code, and keeps that data inside the app, for the people it's meant for.

Your data stays yours

Never sold, never shared

We don't sell data, show adverts or share anything with advertisers, data brokers or insurers. There's no advertising or analytics tracking in the app or on this website.

Stored in the UK, encrypted

Data is stored in London, encrypted in transit and when stored, and backed up daily to encrypted backups. Deleted data leaves the backups within 7 days.

Apple Health stays in Apple Health

Workouts from the Apple Watch are saved to Apple Health with heart rate and calories. That health data stays on your devices: Ironlark never sends it anywhere.

Only the right people see it

A client's record is held by their gym or coach, and only the coaches assigned to that client, and the gym's owner, can open it. Every company's data is kept apart. People training on their own keep a private record of their own.

Separate consent for health data

Health information needs its own explicit, unticked consent, and every consent records the exact version of the policy that was agreed to.

Export and delete, any time

Members can download a copy of everything held about them and delete their account from the app, without having to ask.

Secure by design

No passwords to steal

Sign in with a passkey (Face ID or Touch ID), with Apple, with Google, or with a one-time code by email. There's no Ironlark password to guess, reuse or leak.

Checked on every request

Who can see what is enforced by the database itself on every single request, not just by the screens in the app, so one company's data can't be reached from another.

A record of every change

An audit log records who changed a client's record and when, so access can always be checked.

Young people

A parent says yes first

Anyone under 18 needs a parent or guardian to give consent through an emailed link before any training data is stored, and they can withdraw it later. Under-13s are off unless a gym or coach turns them on.

Open, not private, messaging

Only a young person's own coaches can message them, their parent gets a copy of every message, and nothing is delivered between 9pm and 7am. Notifications never show what a message says.

No public profiles

No social feed, no location and no advertising. Under-18s never appear by name on leaderboards, and reminders stay off unless they turn them on.
