AI Mobile App Assistant
A conversational AI assistant gets built and shipped inside your existing iOS or Android app, tested on real devices.
App users expect to ask for what they need instead of tapping through menus. This build adds a conversational AI assistant to your existing iOS or Android app, woven into up to three screens or flows. It is tested on real devices and delivered as production code in your repository, ready for your next release. Your API keys stay out of the code.
- A conversational assistant built into your existing mobile app
- Tested on real devices before your next release
- Production code in your repository, with no secrets in code

What it is
AI Mobile App Assistant is a software build that adds a conversational AI assistant to your existing iOS or Android app, delivered as production code with up to three assistant-powered screens or flows. It is tested on real devices before release.
Why businesses buy it
Mobile users abandon apps when they cannot find what they need quickly. A well-placed assistant helps them get there, and it can lift engagement on the flows that matter most. Building one in-house takes prompt design, device testing and careful handling of keys that mobile teams rarely have time for. The written scope fixes the screens, APIs and testing before you order, so product owners know exactly what will ship.
Problems this solves
App users leave the app to email support for simple help
A conversational assistant is added to your existing iOS or Android app. Users get help on up to three assistant-powered screens or flows, without leaving the app.
Adding AI stretches a small mobile team that already has a roadmap
The assistant is delivered as production code, with prompts, guardrails and up to two API connections configured. Your developers review and own it rather than build it from scratch.
AI features can behave differently on real phones than in testing
The assistant is tested on real devices before release, with automated tests for core flows and thirty manual scenarios. A recorded technical handoff walks your developers through the code.
A good fit if
You already have a published or in-development iOS or Android app and want to add a conversational assistant inside it.
You can describe up to three assistant-powered screens or flows, such as an in-app help chat, a guided setup or a voice-to-text note capture.
You have a mobile repository, app store access or a technical contact who can review a pull request and test on a device.
You want the assistant native to the app's own navigation, not a web page loaded inside it.
Not the right fit if
The assistant belongs on the web or inside an internal tool, not a mobile app. See AI Feature Integration, or AI Internal Tool Builder.
You want it as a browser extension for desktop use, not inside a mobile app. See AI Browser Extension Assistant.
You mainly need a simple chat widget for customer questions, not an assistant woven into app flows. See AI Website Chatbot.
You do not yet have a mobile app for the assistant to live inside. Start with our Custom AI enquiry form to scope the app itself.
How it works
- Requirements are confirmed. We agree the up to three assistant-powered screens or flows, the app's platform and navigation, and what counts as done.
- The assistant is built into your app's existing codebase, following its navigation and design patterns, with environment-based configuration and no secrets in code.
- It is connected to up to two APIs, such as your backend or the AI model itself, so the assistant can draw on real app data rather than static replies.
- Automated tests cover the core AI flows, and 30 manual test scenarios are run on real iOS or Android devices, not only a simulator.
- Your technical contact reviews the working assistant, with two rounds of changes included to adjust flows, prompts or screens.
- The assistant is delivered ready for your next app store release, with a recorded 60-minute technical handoff covering how to maintain and extend it.
What you provide within 72 hours
Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.
- Repository access to your iOS or Android app's codebase.
- App store or TestFlight access for testing on real devices ahead of release.
- Design assets or reference screens showing how the assistant should look and fit into the app's navigation.
- API documentation for the systems the assistant needs to connect to.
- A technical contact who can review pull requests and test builds on a device.
- Admin access and API keys for every connected system, shared by adding our team as a user or creating a key you control, never by email.
- One decision-maker who can approve the finished assistant.
- An API key for your own AI model account (for example OpenAI or Google Gemini), created for this build with a spending limit.
The 72-hour rule. Send everything on your checklist, including access, within 72 hours of ordering so your build starts on time.

Expected benefits and how to measure them
- Can keep users inside the app when they need help
- Helps a small mobile team add AI without pausing other work
- Leaves your developers owning tested code
- In-app support emails
- Count support emails sent from the app for four weeks before release and four weeks after.
- Assistant usage
- Use your app analytics to count weekly sessions that open the assistant.
- Flow completion
- Compare completion rates for the assisted flows in your analytics, before and after release.
Before you start: Record current support emails from app users and completion rates for the flows the assistant will cover.
These are things to track, not promised results. Outcomes depend on your data, your team and your market.
Running costs
The build itself is a one-time payment, shown before you buy. Running the finished assistant typically costs ~$50–300 a month for hosting and AI usage, on your own cloud account, depending on how many app users engage with it.
AI usage during build and testing is billed the same way, so your cloud and AI provider accounts stay in your name.

How maintenance worksHow this compares
| Do it yourself with a SaaS tool | Hire a custom agency | Upmark Labs | |
|---|---|---|---|
| Price | A bolt-on mobile AI SDK charges a recurring fee per monthly active user | A software agency quotes after a discovery and scoping phase | Ours is one fixed price, shown before you buy |
| Fit | An SDK adds a generic chat screen, not woven into your app's flows | An agency build depends on what was agreed | Ours follows your app's own navigation and design patterns |
| Ownership | An SDK's logic stays inside the vendor's own service | An agency's ownership terms vary by contract | Ours ships as production code in your own repository |
| Delivery | An SDK integrates in days but with limited customization | An agency usually takes several weeks, set per project | Ours has a fixed delivery time shown before you buy, with faster options |
| Testing | An SDK is tested by its vendor, not on your real app builds | An agency build depends on what was agreed | Ours is tested with 30 manual scenarios on real devices |
Questions about this product
What does the AI Mobile App Assistant price include?
One fixed price covers designing, building and delivering an assistant with up to three screens or flows inside your existing iOS or Android app, including automated tests, 30 manual test scenarios on real devices and a recorded 60-minute technical handoff session at the end.
What does the mobile assistant cost to run each month?
Typically $50 to $300 a month for hosting and AI usage on your own cloud account, depending on how many app users engage with it. An app with moderate daily use usually sits mid-range, billed directly to your own provider accounts.
How long until the assistant is ready to ship in my app?
The delivery time for standard, Express and Rush is shown in the price panel before you order. The schedule runs from a complete intake, so it depends on receiving repository access, design references and app store access within 72 hours of ordering. Anything later adds time.
Is the assistant tested on real phones, or just a simulator?
On real iOS or Android devices, not only a simulator. Automated tests cover the core AI flows, and 30 manual test scenarios are run on real device builds, since screen behavior and performance can differ from what a simulator shows.
Do you need access to our app store account?
App store or TestFlight access is needed so we can test on real devices ahead of your next release, but publishing the update to the store itself stays your decision and your action. We deliver a build ready for you to release when you choose.
Can we change the assistant's flows after the technical review?
Yes. Two rounds of changes are included while your technical contact reviews the working assistant on real devices. After launch, smaller adjustments, such as a prompt tweak or a flow change, fit inside the monthly change hours included with maintenance.
Will the assistant work on both iOS and Android?
It is built for the platform your app already runs on, agreed with you during intake. If your app exists on both iOS and Android, building the assistant into both platforms sits outside the base scope and is quoted separately as a Change Quote before that work begins.
