Who is AppsTango? Where are we?
Start here for our location, services, and published package prices.
Where is AppsTango based?+
AppsTango is based in Lehi, Utah. We work with founders and businesses on mobile apps, web products, cloud infrastructure, and AI workflows. You can meet with us in Lehi or discuss your project remotely.
What does AppsTango build?+
We build iOS and Android apps, web applications, AWS infrastructure, and AI workflows. Projects range from a focused first release to a phased enterprise engagement. The services and case studies pages show the types of work we take on.
How much does an AppsTango app project cost?+
MVP Launch starts at $10k for one platform. Production Hardening starts at $15k; Full Cycle starts at $35k for two platforms. Enterprise engagements are custom scoped. Final price depends on the agreed deliverables.
Can AppsTango build an AI workflow for my business?+
Yes. We start with the workflow and identify which steps need a model, which can use rules, and where a person should review the result. The scope can include Amazon Bedrock, AgentCore, integrations, evaluation, and monitoring.
What should I compare when choosing an app development team?+
Ask for relevant project examples, a clear scope and price, named responsibilities, an agreed delivery schedule, account ownership, and post-launch support terms. Confirm what is included in submission, integrations, content, and ongoing operating costs.
# general
How AppsTango works.
What happens on the free strategy call?+
A free 30-minute conversation about your scope, budget, and next step. A fixed-price proposal follows confirmed scope.
What does a fixed-price package cover?+
It covers the deliverables and acceptance criteria in your agreed scope. We confirm the price before work begins. If scope changes, we agree the additional work and its price in writing. No hourly billing.
Are the package prices fixed quotes for every project?+
The published prices are starting points. A focused MVP starts at $10k; the final proposal reflects your platforms, workflows, integrations, and release requirements. A larger feature set needs a larger scope.
How long does a project take?+
Production Hardening targets 21 days; MVP Launch targets 30 days; Full Cycle targets 6 weeks. Enterprise schedules are agreed by phase. 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.
What support is included?+
Production Hardening and MVP Launch include 30 days of post-launch support. Full Cycle includes 90 days. Enterprise support coverage and service levels are agreed in the proposal.
Do we own the code and accounts?+
Yes. Your code lives in your GitHub organization, infrastructure runs in your AWS account, and app listings use your developer accounts. Handoff includes the agreed documentation and operating access.
How does pay-on-delivery work?+
Pay-on-delivery ties invoices to the deliverables and acceptance criteria agreed in your statement of work. The signed agreement sets the payment schedule and any deposit, cancellation, or missed-milestone terms.
Can you work with an existing app or prototype?+
Yes. We review what is already in place, identify the release risks, and agree what can be kept or needs more work. Production Hardening is designed for this starting point.
# offers
By productized offer.
Each offer has its own follow-ups. Open the group, then jump to the full page if you want the comparison and process.
Pay on delivery
full offer →Does every project have the same payment terms?+
No. Your statement of work defines the schedule and the applicable deposit, acceptance, cancellation, and missed-milestone terms. We discuss those terms before you commit.
Does this change an existing contract?+
No. Your signed agreement continues to govern the engagement. Any changes must be agreed in writing.
How do we handle additional features?+
We agree the additional scope, price, and schedule in writing before starting that work.
A focused production MVP
full offer →Is $10k the price for any app?+
No. From $10k is the starting price for a focused first release on one platform. Integrations, workflows, and other requirements determine the final fixed-price proposal.
Is 30 days guaranteed?+
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.
What if we need iOS and web?+
Full Cycle starts at $35k, includes two platforms and 90 days of post-launch support, and targets 6 weeks for the agreed scope.
What if scope grows?+
We agree the additional deliverables, price, and schedule in writing before starting the new work.
Put AI to work
full offer →Does every step need AI?+
No. Rules, forms, and ordinary APIs often handle predictable steps better. We identify where model reasoning adds value and where it introduces unnecessary risk or cost.
Can it connect to our existing tools?+
We review the available APIs, permissions, and data handling requirements during scoping. Integrations are included when agreed in the proposal.
Can we require a person to approve actions?+
Yes. Human review and approval steps can be part of the workflow and its acceptance criteria.
Your project is stuck
full offer →Can you finish what another team started?+
Sometimes. The answer depends on the code, account access, documentation, and remaining requirements. A technical review determines what can be retained.
What should I bring to the call?+
Bring a description of the intended product, what currently works, and the issues blocking the next release. Any technical access or documents can be discussed as a follow-up.
Can you advise on ending our current contract?+
We can identify technical handoff requirements. Your legal adviser should review contractual obligations before you change or end an engagement.
An idea needs a first release
full offer →Do you work with early-stage founders?+
Yes. MVP Launch starts at $10k for a focused first release. We discuss scope and budget before proposing a build.
Can we start from a prototype?+
Yes. We review the prototype and identify what can be reused and what production work remains.
Will the call include a final quote?+
A free 30-minute conversation about your scope, budget, and next step. A fixed-price proposal follows confirmed scope.
Your dedicated dev team
full offer →Can the team work with our existing engineers?+
Yes. We agree responsibilities, communication, code review, and access with your existing team during onboarding.
What happens to the code when the engagement ends?+
It remains in your repository. Handoff requirements and support are agreed in the engagement terms.
How soon can a team start?+
The start date depends on availability, the required skills, and access to your systems. We confirm those details in the proposal.
# services
By practice area.
Technical questions sit on the service pages they belong to. Tap through for the full stack and deliverables.
iOS development
full service →Can you update an app we already have?+
Yes. We start with the current code, release process, and the feature you need. That review helps separate a targeted update from a larger rebuild.
Do you use SwiftUI or UIKit?+
We choose around the product and its existing code. SwiftUI is a common starting point for new interfaces; UIKit remains useful for established apps and specific interactions.
Will you handle App Store submission?+
We can include submission and reviewer feedback in the agreed scope. The release remains in your developer account, and Apple controls review timing and approval.
What determines the cost and schedule?+
The number of user journeys, integrations, device requirements, and existing code all affect the work. A focused MVP can use a fixed-price scope; the consultation identifies what belongs in that first release.
Android development
full service →Can you support phones, tablets, and foldables?+
Yes, when included in scope. We agree device and screen-size coverage before design and testing, so the release criteria are clear.
Can the app work with our current backend?+
We review your APIs, authentication, and data access before recommending changes. A new mobile app does not automatically require replacing the systems you already use.
Do you support offline use?+
We can scope local storage, synchronization, and conflict handling for the actions users need offline. Those decisions depend on the data and the consequences of a delayed update.
Who owns the Google Play account and code?+
Your app is released through your Play Console account. Source code and handoff documentation are delivered as defined in the signed scope.
AWS cloud infrastructure
full service →Can you work in our existing AWS account?+
Yes. We review the current setup and agree the access needed for the work. Your team retains account ownership and visibility into the infrastructure.
Do you build new infrastructure or improve what we have?+
Both. We start with the workload and its constraints. Keeping a working component can be the right decision when the issue is deployment, monitoring, or access rather than architecture.
Can you help with a migration?+
We can scope a migration after reviewing data, dependencies, traffic, and downtime tolerance. The plan should define validation and rollback before any production cutover.
What happens after the initial work is complete?+
You receive the agreed code and operating documentation. Continued delivery or operational coverage can be scoped separately; fractional AWS is an option for recurring capacity.
UI/UX design
full service →Can you work with our existing design system?+
Yes. We review the current components and patterns before proposing additions. The goal is a usable, consistent workflow your team can maintain.
Will we get a clickable prototype or finished code?+
The design scope defines the deliverable. A clickable prototype and implementation specifications are different from production code; we can scope either or both.
Do you test the designs with users?+
Usability testing can be part of the engagement. We agree who should participate, which tasks to test, and how findings will affect the next iteration.
How do you approach mobile and accessibility?+
We define responsive layouts, keyboard behavior, content structure, and component states alongside the main screens. The agreed review criteria become part of the handoff.
AI agents on AWS
full service →Does the task need an AI agent?+
Not always. A deterministic workflow may be simpler when the rules and inputs are predictable. We use the consultation to identify where model judgment would add value.
How do you reduce wrong answers or unsafe actions?+
We define allowed tools, validate inputs and outputs, test representative tasks, and retain approval steps for consequential actions. No model or guardrail removes all risk; the workflow must handle failure.
Can the agent use our internal systems?+
That depends on the available APIs, permissions, and data requirements. We agree what the agent may read or change and build the integration around those boundaries.
Do you offer ongoing AI ownership?+
Yes. The Forward-Deployed Engineer offer is for recurring production AI work, including evaluations, guardrails, and operations. A fixed-scope first workflow and an ongoing role are separate engagement options.
Web development
full service →Can you improve an existing website?+
Yes. We review the user journey, content, current platform, and integrations. A focused change to the important pages or forms may be enough.
Who hosts the website?+
Your team owns the hosting account. We agree the platform and operating responsibilities based on your existing stack, traffic, and maintenance needs.
Do you include SEO and conversion tracking?+
Technical SEO and agreed conversion events can be included in scope. We define which actions matter, how they are measured, and any consent requirements before implementation.
Can you guarantee a Lighthouse score or more leads?+
We can agree performance targets and verify the implementation. A single score varies by test conditions, and lead volume also depends on traffic, offer, and demand. Results should be measured after release.
Fractional AWS team
full service →How is this different from a fixed-price app build?+
A fixed-price build defines a specific delivery scope. Fractional work reserves recurring capacity for a changing backlog. We help select the model that matches your roadmap.
How is this different from a Forward-Deployed Engineer?+
Fractional AWS focuses on recurring cloud and application delivery. The Forward-Deployed Engineer offer focuses on production AI workflows, evaluations, guardrails, and operational ownership.
How does a part-time engineer stay in context?+
We agree a recurring collaboration rhythm, use your repository and tracker, and document decisions. Capacity planning must allow for reviews, meetings, and handoffs as well as implementation.
When can someone start?+
We confirm current availability and the onboarding work during the consultation. The start date is agreed in writing after the role and capacity are clear.
Can the capacity change?+
The published service is month-to-month. Your agreement defines notice, available capacity, and how changes take effect at the next cycle.
