Top IT Service Providers for iOS App in the UK

799 IT service providers ranked by rating, review volume and listing quality.

iOS development covers applications for iPhone and iPad, and the work of getting them through App Store review and keeping them there. The platform is more uniform than Android — fewer devices, faster OS adoption — but the review process is a real project risk that inexperienced teams underestimate.

Ask who holds the developer account: if the agency does, your app lives in someone else's Apple relationship, and moving it later is administrative work you will not enjoy. Ask how rejections are handled, and whether the quote includes the rounds of resubmission that most non-trivial apps need. Ask what happens each September, when a new iOS version arrives and something in your app stops behaving.

Want your company here?

Between them, the 600 best-ranked of these 799 IT service providers cover android (590), web development (575), web design (493) and HTML5 (421). 597 of them have written a profile you can read before you get in touch.

We list 800 IT service providers in the UK listed for iOS app development. The order comes from what each firm publishes and what has been verified about it, never from payment — at the top right now: Toru Digital, Abbacus Technologies and Apptology Limited.

How is this ranking worked out?

The order comes from what each firm publishes and what has been verified about it, and never from payment:

Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
Earned trust: verification, awards and the other checks a firm has actually passed
Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

Client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.

Sponsored listings are labelled and shown apart from this list. How rankings work

Only firms whose profile names the UK are counted here, so a firm that lists a town but no country is not yet included.

Where else can I look?

The same list elsewhere: USA (1,452) · India (849) · Germany (398) · Canada (236).

Other specialisms in the UK: UI/UX design (941) · e-commerce (854) · Android app development (812) · WordPress (752) · PHP development (728).
