You want to be the icon on their phone. Not a website they have to go looking for again.
Not a build you finish once — a release process that never really stops.

app stores that can pull your listing if nobody keeps it current
What actually makes a mobile app different from a website
Four things, or it's decoration
REVIEW
Approved before it's live
Every version has to clear Apple's and Google's own review before a customer can download it — not instant, and not guaranteed to pass on the first try.
UPDATES
Kept current, or it stops working
Phones get a new OS roughly once a year. An app that isn't rebuilt against it eventually breaks, or quietly disappears from the store.
DEVICES
Right on every screen it lands on
Different phone sizes, OS versions and manufacturers all render it slightly differently — a website adapts itself; an app has to be built and tested for the difference.
RELEASE
A process, not a page you can just edit
Fix a typo on a website and it's live in seconds. Fix one in an app, and it goes back through review before a customer ever sees it.
+ a website has none of these constraints — no review queue, no forced updates, no store to be delisted from
+ most SMEs asking for 'an app' are actually asking to be findable and look legitimate on a phone — a mobile-friendly website does exactly that, without any of the four above
What actually happens after launch
This is an illustrative build, not a real client's timeline — but it's the shape of what happens after most apps ship:
Nothing about the app itself changed. The phones underneath it did — and unlike a website, that isn't something you can just leave.
Delivering the code doesn't hand off who keeps the account current
A published app sits under a developer account that has to stay active, verified and in good standing — or the listing stops working regardless of how well the app itself was built. That responsibility doesn't end when the build is handed over.
Apple's and Google's developer terms require an active, verified developer account behind every published app — a standing requirement, not a one-time signup. The exact terms, and who this account is registered to, are being confirmed with the module owner before this page states it either way.
The one question that decides this
Anyone can build an app that works on launch day. Almost nobody is still the one rebuilding it two OS versions later.
What happens the first time a phone update breaks something
A one-off app studio and OCTIS do the same build work. The difference shows up after launch, the first time a phone update breaks something:
What a one-off build can't stay around to do
What they do well
A good app studio genuinely earns its fee on the build itself — the design, the code, the first submission. That part doesn't need OCTIS.
What their shape can't reach
A project that ends at handover has no reason to still be checking Apple's and Google's requirements a year later. Nobody is watching for the policy change that quietly breaks the app, because the engagement that would have caught it already closed.
The line an OS update draws
It isn't gradual. The app works, until the version it was built against is no longer accepted — and then it doesn't.
What has to be wired up separately
0
extra systems to connect — the app's payments, CRM and customer records run on the same OCTIS account the rest of your business already uses.
One codebase, not two
There's no price yet — this is the actual sequence
A mobile build is scoped, not shelf-priced. This is what actually happens, and where most other quotes stop:
You tell us what the app needs to do
bookings, ordering, loyalty — whatever the actual job is, not a feature list copied from someone else's app
We scope it against a fixed quote
agreed once, before the build starts — not billed by the hour
We build once, submit to both stores
one codebase for iOS and Android, review handled by us
We stay on it after launch
OS updates, store policy changes and fixes are part of the engagement — the stage every other quote usually leaves out
The build is the part every quote already includes. Stage four is usually the one that's missing — and it's the one an app can't actually skip.
Who does the work
OCTIS's own IT team
The build, the store submissions and the ongoing maintenance are handled in-house, by the same people — not handed off once the app is live.
What you bring
What the app needs to do, your brand, your SSM number
We turn that into a scope and a fixed quote before any build starts.
Timeline
Not instant
Store review alone can add days once the build is otherwise ready — Apple and Google set their own review queue, not us.
Who this isn't for
You mainly want to look legitimate and be found on a phone
A mobile-friendly website does that job for a fraction of the price, with no store review and no forced update cycle. Most people asking for 'an app' actually want this instead — worth ruling out before requesting an app quote.
Not covered
- Approval from Apple's App Store or Google Play is never guaranteed on the first submission — both platforms can reject a build and ask for changes, on their own timeline, not ours.
- If what you actually need is to look legitimate and be reachable from a phone, a mobile-friendly website almost always does that job faster and cheaper — no store review, no forced update cycle, nothing to resubmit. Ask us honestly which one fits before requesting an app quote.
- The 30-day money-back guarantee covers exactly two services — new company incorporation and transfer of company secretary. It does not apply here. What applies instead: the quote is fixed once agreed, and staying current after launch is part of the engagement, not a recurring surprise.
- We don't control how long Apple or Google take to review a submission, or when either platform changes its requirements — only how quickly we respond once they do.
Do I actually need a mobile app, or would a website do?
Often a website. If the goal is mainly to look legitimate and be reachable from a phone, a mobile-friendly website does that without app-store review or a forced update cycle, and costs a fraction as much. An app earns its place when you need something a browser tab genuinely can't do well — push notifications, offline use, or a home-screen icon customers open often.
What determines the price of a custom mobile app?
Mainly what the app needs to do — bookings, payments, offline behaviour, push notifications and integrations vary far more between projects than a single web page does, which is why app builds are usually quoted per project rather than sold at a fixed price. 
scopes the actual requirement first, then agrees a fixed price before the build starts.
What happens if Apple or Google reject an app submission?
It's not unusual — both platforms review against their own guidelines and can ask for changes before approving, on their own timeline. handles the resubmission as part of the build engagement, not as a separate charge.
Can a custom mobile app connect to a business's existing CRM and payment system?
Yes, if it's built to — a custom app can read and write to the same account already holding a business's CRM, payments and customer records, instead of keeping its own separate copy that needs manual syncing. builds every app this way, on the same account as the rest of a client's setup.
Do I need to arrange app maintenance separately after it launches?
Usually, yes, with most developers — OS updates and store policy changes keep coming after launch, and someone has to keep resubmitting the app or it can be delisted or stop working without warning. includes that as part of the same build engagement rather than a separate thing to notice and re-commission.
The build was never the part that mattered most. Still being the icon on their phone a year from now is.
Tell us what the app actually needs to do. We'll scope it, build it once for both stores, and stay on it after launch — or tell you honestly if a website would do the job for less.
