An iOS and Android app built around the one thing your users come back for.
We build cross-platform apps from one codebase: one core loop, sign-in, push notifications, offline basics and store submission. The app is built by a vetted senior mobile engineer, with us as tech lead, backend engineer and reviewer of every change. The app ships in every language your users need; English and Arabic with correct right-to-left layout are native to how we build.
On request. Delivered with a vetted specialist under our lead, when one has a slot.

Ways of working
Most engagements are fixed-scope projects: numbered deliverables, a fixed price and a fixed date, all in writing before work starts. Product builds run as focused sprints with a working demo every week. After handover, Run keeps a system monitored, updated and improving month by month. The first call settles which one fits, and the quote states it in writing.
The AI angle
Add AI to the app
A photo that becomes a filled-in form, a support assistant, or search that understands intent, running through your backend with the same permissions and logs.

Why is this line on request?
Because we only sell what we can deliver well. Mobile work is built by a vetted senior mobile engineer under our lead, and we take a project only when that engineer has a slot. Ask, and we will give you an honest start date.
Native or cross-platform?
Cross-platform for almost every business app: one codebase, both stores. If your app needs heavy native hardware work, we will say so and refer you to a native specialist.
Who publishes the app?
You do, under your own developer accounts. We prepare the store listings and handle submission and review.
Does it work in Arabic?
Yes, and in any other language your users need. Right-to-left layouts, Arabic typography and multilingual content are part of the build.
