Services · Mobile app development · Fitness apps
Codeeo offers fitness app development London coaches, boutique brands and health start ups use to sell training to busy people. We build iOS and Android apps with adaptive plans, video sessions, wearable data and subscriptions, designed for clients who squeeze a workout between a Northern line commute, a desk in the City and a Saturday parkrun. The aim is simple: an app your clients open every day because it plans around their real week.
Our team works with London clients remotely. Discovery, design reviews and sprint demos all happen by video call. We are a team of 80+ across Dubai, Riyadh and Karachi, rated 4.7 from 23 Google reviews.

What we build for London fitness businesses
London clients are not short of fitness apps. They are short of time, and they delete anything that adds friction. A product that wins here has to earn its place on the home screen in the first week: it must know when the client can train, adapt when a meeting runs late, and work in a basement studio or on a train with patchy signal.
London also attracts brands that want to scale beyond one postcode, from a coach with a following in Clapham to a studio label selling digital memberships across the country. So we plan the product with growth in mind, while keeping the first release narrow enough to launch and learn from. Here are the capabilities we scope most often for London projects, roughly in the order founders tend to prioritise them.
With permission, the app reads busy blocks from the client's work calendar and suggests a session that fits: a twenty minute mobility routine before an early meeting, a longer run on a free evening. Missed sessions reshuffle the week instead of piling up as guilt.
Plans survive the chaos of a London working week.
Follow along sessions that download over wifi and play without signal, so a client can stretch on the Tube or train in a hotel room. Adaptive streaming keeps quality sensible on mobile data, and downloads clear themselves to save storage.
Workouts still happen when the connection drops.
Structured blocks for 5k, 10k, half marathon and marathon goals, counting back from race day with taper weeks, long run progression and recovery days. Clients training for spring road races or their weekly parkrun see exactly what each session is for.
Event goals become a plan clients can follow.
Clients who run or cycle to work can tag those trips as training, so the plan counts them rather than adding another session on top. GPS traces stay on the device unless the client chooses to share them with their coach. Santander Cycles hire trips can be logged manually in a couple of taps.
Active commutes count towards weekly targets.
Heart rate, sleep, HRV and workouts pulled from Apple Health, Google Health Connect and, where clients use them, Garmin, Oura or Whoop. Fitness tracking app development London founders ask for usually begins with this layer, because recovery data decides whether today is a hard day or an easy one.
Training load adjusts to how clients actually slept.
Messaging, voice notes, form check video uploads and scheduled check ins between client and coach. For personal trainer app development London coaches commission, this is often the centre of the product, since it is what clients pay a premium for.
Clients feel coached, not just subscribed.
Team challenges sold to employers in Canary Wharf, the City or King's Cross, with company level sign up, private leaderboards and aggregate reports that never show an individual's health data to the employer. Challenges can run for a month or a single week.
A business to business channel alongside consumer sales.
Monthly and annual plans, upgrades between tiers and clean cancellation. We set this up through Apple and Google in app purchase or web checkout, depending on what the stores allow for your product.
Billing that is clear, fair and easy to manage.
A web tool where your team uploads videos, writes programme notes, schedules new drops and edits exercise libraries without asking a developer. Releases of new content no longer wait for an app store update.
Fresh programmes go live the day they are ready.
Dashboards showing where new members drop off, which programmes keep people training into month three and which notifications get ignored. Event tracking is designed with consent in mind, so analytics do not quietly collect health data.
Decisions about the product rest on evidence.
Who we build for
The London fitness market is crowded, so the right first release depends heavily on where you sit in it. We hear from four broad groups. Each has a different reason to build, a different first feature set and a different risk to manage. None of them needs software for running a gym floor; they need a product that holds the client relationship between sessions. If you fit more than one group, that is common, and discovery helps decide which comes first.
You train executives in Mayfair or Chelsea in person and have more demand than hours. An app lets you sell a hybrid tier: two sessions a month face to face, with programming, check ins and messaging in between. The first release is about your brand and your coaching voice, not features for their own sake. Clients should feel the same attention they get in the room, and your diary should stop dictating your income. Pricing tiers stay entirely under your control from the dashboard.
Hybrid coaching extends your hours without extending your day.
Your classes in Shoreditch, Clapham or Notting Hill have a loyal following, and members ask for something to do when they travel or cannot get to the studio. We build an on demand library and programmes in the studio's style, with class booking kept in the system you already use and linked rather than rebuilt. The app becomes a reason to stay a member, and a product you can sell to people who live outside London.
Keep the booking system you have and add what members are asking for.
You have a new idea, perhaps adaptive strength programming or a women's health product, and investors who want evidence quickly. Workout app development London start ups need at this point is disciplined: a narrow first release, honest analytics and an architecture that will not need replacing at the next round. We help cut the scope to what proves the idea and leave room for what comes after. Investors also tend to ask about data protection, so we document those decisions as we go.
You run a club or a social running group that meets in Victoria Park, along the Thames or on Hampstead Heath, and messaging apps no longer cope. Members want routes, plans for upcoming races, meet up details and a sense of belonging. We build community features with moderation tools from day one, because any feature where members post content brings duties under the Online Safety Act. Club officers get simple tools to approve members, pin posts and remove anything that breaks the rules.
Working with Codeeo
Coaches and smaller brands usually begin with a fixed scope first release, then move to a monthly retainer for improvements, content features and store updates. Funded start ups often prefer a dedicated team that stays with the product through several releases. What drives cost is the number of user types, how much video you host, which wearables you integrate, how complex your billing is and whether you need a web version as well as the apps. We set out each of those choices in plain language before work begins. Running costs such as hosting, video delivery and third party data services are listed separately so you can budget for life after launch.
A defined build with a deadline
We agree what the product has to do, write it down with a price and a date, and build exactly that. Changes are priced before they are made, not discovered on the invoice.
A product that keeps evolving
Named engineers who work your hours, join your standups and stay on the codebase. You direct the backlog; we own the quality of what ships.
Something live that needs looking after
A monthly block of hours for improvements, fixes and the small requests that otherwise wait months. Unused hours carry for a quarter.
Technology
We choose tools you can live with long term. Typical London builds use React Native or Swift and Kotlin for the apps, a cloud backend in a UK region, a video platform for streaming, and HealthKit and Health Connect for device data. Every choice is documented, so another team could pick up the code if you ever needed them to.

Competition and client expectations are higher.
London clients compare your app with the best known global brands on their phone, so polish and speed matter from the first release. They also live irregular weeks, commute in ways that disrupt signal and routine, and often pay for premium coaching. That pushes us towards calendar aware plans, offline video and coaching tools, and away from generic workout lists that clients already have for free. A coach in Hackney and one in Richmond will want different things from the same app, and we design for that variety.
