User tasks, platforms, integrations, testing and release.
Cloud, messaging, third-party services and ongoing usage.
Support terms, maintenance and the next release.
A scope model, not a price estimate. Define each category in the proposal.
An app budget is a set of decisions, not just a number. A useful quote names the users, the workflow, the platforms and the systems that must connect. It also explains what happens after launch.
This guide is a way to compare proposals. The package figures below are AppsTango starting prices, not a market average or a quote for every idea.
Build: product definition, design, engineering, testing and release preparation. Ask which deliverables are included and how you will accept them.
Operate: hosting, storage, messaging, third-party services, store accounts and any model usage. These costs depend on traffic and architecture; they are separate from a development fee unless your agreement says otherwise.
Improve: post-launch support, platform updates and the next product release. A support period does not mean unlimited new features.

Support agreed by engagement
Delivery targets depend on the agreed scope, access, content, and feedback. We confirm the schedule before work begins. App Store or Play Store submission is included where applicable; store approval timing is outside the build schedule. See package details.
Delivery targets depend on agreed scope, access, content and timely feedback. App-store submission and store approval are separate events. The platform controls review timing.
Start with one user and one complete task. Then check the expensive edges: several account roles, offline behavior, migration from an existing system, integrations with limited documentation, device hardware and sensitive data.
A second platform may add work even when code is shared. Testing needs to cover each supported device and environment. An existing app may need a focused hardening engagement before new features are useful.
Ask each vendor to identify assumptions. “The customer supplies a working API” is very different from “we design and build the API.” A clear exclusion is more useful than a low number built on an invisible assumption.
The Black Car IQ project is a useful example of defining a complete journey: service information, trip details and a quote request. It is evidence of a workflow, not a claim about the cost of that engagement.
Bring your most important user task, the systems already in place, the budget range and any fixed deadline. A free 30-minute strategy call is for scope, budget and the next step. A fixed-price proposal follows confirmed scope.
See the current package details and delivery method before comparing the total commitment.

Decide which steps need a model, which need rules and where a person should review the result. A practical framework without an assumed 80/20 ratio.
Prepare the build, reviewer access, metadata and privacy information before submission. Approval and review timing remain Apple’s decisions.
