Mobile App Development in the UK

About Mobile App Development

We build cross-platform apps in Flutter and React Native, wire up the backend, push, and offline sync, and hand them to the App Store and Play Console for you. A senior team in Noida, flat quotes, and a written scope before any code.

What the engagement includes

• Senior engineers on your app from day one. No junior offshore team behind an account manager, no handoff after you sign.
• Direct access to the people writing the code. You talk to the developer, not a layer that relays your questions and loses half of them.
• Both app stores handled end to end, including signing, listings, and the review process, so you are not learning Play Console under deadline.
• Flat INR quotes against a written scope, turned around in 24 hours. We can invoice in USD to a foreign parent entity if you need that.
• 70 plus projects shipped for clients in India, the USA, Canada, the UK, and the UAE, so this is not our first launch.
• Honest scoping. If you need one app and not three, or a web app instead of a native one, we will tell you before you spend.

Gig worker checks, the hand-held phone law and MHRA rules for health apps: what changes in a UK mobile build

If the app is how people find paid work, the Right to Work Scheme moved underneath it on 1 October 2026. The Home Office employer's guide published that day treats a delivery platform as the employer, for right to work purposes, of someone who logs into its app when they want to work, accepts delivery requests and is paid per delivery, and it treats an online matching service that sends a cleaner to a customer's home the same way. For those arrangements a civil penalty can apply where the work began on or after 1 October 2026, at up to £60,000 per illegal worker. Most of what follows lands in the worker app. A digital check has to go through a right to work digital verification service provider on the OfDIA register, and for a British or Irish passport that provider verifies the chip by passive authentication, which on a phone means an NFC read inside the onboarding flow. Anyone who does not want a digital check must be offered a manual route and must not be treated less favourably for choosing it. Where substitution is allowed, no substitute may work before their own right to work is verified, and the check cannot be left to the worker who nominated them. The guide also asks for proportionate systems showing that the person doing the job is the person who was checked, naming facial recognition and re-verification at set intervals, with a Home Office recommendation of at least once in any 24 hour period or shift. So going online starts with a face match against the checked identity, jobs are offered only to accounts whose check is current, and each completed job is logged against a verified person, because those records are the evidence the guide lists. Time-limited permission becomes a dated prompt so the follow-up check happens on or before expiry. Whether your arrangements fall in scope is for your own counsel.

Apps used behind the wheel, by couriers, private hire drivers or field engineers, meet a stricter phone law than many product teams assume. The government's guidance says it is illegal to hold and use a phone, or any device that can send or receive data, while driving, for any reason and whether it is online or offline, and that the rule still applies when stopped at traffic lights or queuing in traffic. The exceptions are narrow: calling 999 or 112 in an emergency when it is unsafe or impractical to stop, being safely parked, making a contactless payment in a vehicle that is not moving, and parking the vehicle remotely. A device may be used hands free, in a cradle or windscreen mount or by voice, as long as it is never held and does not block the view of the road, and the police can still prosecute a driver who is not in proper control because they are distracted. Holding and using one carries six penalty points and a £200 fine, and a driver who passed their test in the last two years loses their licence. For an app whose users drive for a living that is a product requirement. A job offer that expires in a few seconds invites the driver to pick the phone up at the lights, so offers are held until the vehicle is stationary, judged from the device's motion and location data, or accepted with one large target and by voice on a mounted phone. Photo proof of delivery, signature capture and chat are switched off while the vehicle is moving rather than merely discouraged, and the screen a driver sees on the move is designed for a mount. We test those flows with the phone in a cradle rather than in a hand at a desk, because that is how the law expects them to be used. How the rules apply to your own drivers is for your counsel.

Health and wellbeing apps meet a regulator that reads the marketing as well as the code. Under the MHRA's guidance on digital mental health technology, first published on 3 February 2025 and updated on 29 July 2026, whether an app counts as software as a medical device turns on its intended purpose and functionality as shown in its labelling, instructions and promotional material, websites, social media and adverts included, and on how typical users understand and actually use it. One of the MHRA's own examples is an app described on its website as supporting wellbeing while its social media suggests it reduces the risk of depression, and the guidance says the maker should either regulate it as a medical device or remove those inferences. So the store listing, the onboarding screens and the copy in push notifications are part of the regulatory position, and a growth team rewording the store description can move a product into scope without a line of code changing. If the app does qualify, the route depends on its class: class I software is self-certified and registered with the MHRA, while class IIa and above needs an approved or notified body. The point peculiar to this market is the store itself. The MHRA notes that many app stores have a UK category but do not separate Great Britain from Northern Ireland, so a device placed on the market through them needs to comply with both the GB rules under the UK Medical Devices Regulations 2002 and the EU rules that apply in Northern Ireland. That decides which classification rules apply and what the labelling inside the app has to say, and it is far cheaper to settle before the listing is written and the first build is submitted than after launch. Whether your app has a medical purpose, and which class it falls into, is for your own regulatory adviser.

How we work with UK clients

UK engagements tend to start with procurement questions rather than technical ones. Who holds the data, which law governs the contract, whether you can produce a record of processing if the ICO asks. We answer those in the proposal instead of leaving them to a legal review three weeks in, because that review is where UK projects usually stall.

Invoicing is the other thing worth settling early. We are outside the UK, so services we supply generally fall under the reverse charge and your finance team accounts for the VAT rather than paying it to us. Our invoices say so explicitly. We quote in pounds, the figure does not move with the exchange rate mid-project, and payment by bank transfer avoids the card fees that make a five-figure invoice unnecessarily expensive.
