Disclaimer

Last updated 11 August 2026. The calculator and the 15 cost guides on this site are budgeting tools. They are designed to give you a defensible range to plan against — not a price, and not professional advice.

An estimate here is not a quote. It is a directional figure published as a range — 15% below to 22% above the model’s calculated value — generated by a documented formula from the options you selected. It creates no offer, no price commitment and no contract.

What the numbers are

The calculator combines a baseline for the complexity you picked with the features, back-end architecture and infrastructure you selected, then applies multipliers for app category, platform, design level and expected traffic. QA and project management are added as a share of everything above them. The baselines derive from delivered mobile app projects at blended US delivery rates. The formula and every multiplier in it are set out on the about page.

What the numbers are not

Not a quote or an offer. A binding price comes only from a written, signed agreement after a scoping process.
Not a guarantee of cost or schedule. Real projects move on requirements you have not discovered yet, integration counterparties who control their own timelines, and decisions that take longer than planned.
Not a market survey. These are our delivery economics. Another vendor may quote materially more or less for the same brief, and a lower quote is not necessarily comparable scope.
Not complete. Estimates exclude content production, third-party licences and subscriptions, ongoing cloud and bandwidth costs, app store developer fees, paid marketing, and post-launch maintenance. Each exclusion is itemised on the about page.

Not legal, regulatory or compliance advice

This site references compliance and platform regimes including HIPAA, SOC 2, PCI DSS, GDPR, COPPA and FERPA, along with Apple App Store and Google Play policies on payments, privacy and content. Those references are descriptive, included so you can recognise the work a budget line represents.

They are not legal or regulatory advice, not a compliance assessment, and not a certification that any system, programme or vendor — including ours — satisfies any statute, rule, standard or app store policy. Rules change, enforcement positions change, store review outcomes vary, and how any of it applies depends entirely on your organisation, your data flows and your risk posture. Engage qualified counsel and, where relevant, a qualified security assessor.

Named apps and companies

Apps and companies referenced on this site — for example Uber, Amazon, Netflix, TikTok, Instagram, Airbnb, DoorDash and Spotify — appear only as recognisable examples that help you calibrate scope and complexity. They are the trademarks of their respective owners, are used for identification only, and their appearance implies no affiliation with, endorsement of, or partnership with Taction Software Solutions.

An estimate for “an app like X” prices software of comparable shape. It does not price the years of iteration, the operations, the content rights or the marketing spend that made the named product what it is, and no comparison should be read as a claim that it does.

AI-related content

Content on this site reflects our standing position: AI assists, humans decide. Cost figures for AI features assume human-in-the-loop workflows and an evaluation harness, and they price building the feature rather than running it — model usage is a per-request cost that grows with adoption. We make no representation that any model, provider or architecture named on this site is appropriate for your use case, and naming a provider is not an endorsement.

Third-party pricing and names

Figures attributed to third parties — app store fees, payment processing rates, map and identity licence costs, cloud and bandwidth costs — are market ranges observed at the time of writing. They are set by those parties, not by us, and change without notice. Verify them directly before relying on them. All third-party names are trademarks of their owners, used for identification only, and their appearance implies no affiliation or endorsement.

No relationship created

Using this site does not create a client, consulting, advisory or fiduciary relationship with Taction Software Solutions or Taction Software LLC (USA). No confidential information should be sent to us on the assumption that such a relationship exists.

Independent verification

Before you commit budget, sign a contract, raise capital against a figure or present one to a board, validate it independently — through a scoping exercise, competitive quotes, or your own delivery data. If a number here does not match what you are being quoted, we would like to know: tell us via the contact page and we will either correct it or document the assumption that explains the gap.
