iOS app development cost for technology & saas

There is no single figure, and quoting one would be the least useful thing this page could do — the same pairing spans several-fold depending on scope, compliance and how many surfaces you ship. What this page gives you instead is what the pairing demands: the regimes that may apply, the systems of record you will be asked to integrate with, the device matrix and the release path. The calculator below is already fixed to iOS and technology & saas — answer what is left and it returns a cost range, hours, timeline, team and running costs for your scope.

Because technology & saas brings its own obligations before you write a feature: SOC 2 Type II, GDPR, CCPA / CPRA may apply, you will be asked to integrate with systems like Stripe and Auth0 / Clerk / Cognito, and there are typically 6 distinct roles rather than one. The platform contributes its own separate costs — the device matrix, App Store review — and those are independent of the industry.

Slightly, and almost entirely because of testing. The engineering itself is comparable, but iOS has a handful of screen sizes and two or three OS versions in play, versus 20–30 meaningful Android configurations. That difference is typically 30–50 hours per release cycle. Against that, iOS adds App Review as a schedule dependency and a $99 annual account, and requires Mac hardware to build on.

Budget one to four days per submission and expect at least one rejection on a first release. The common causes are predictable and worth designing around up front: no in-app account deletion, offering third-party sign-in without Sign in with Apple, unclear subscription pricing, and privacy labels that do not match actual data collection. Each round trip costs a day or two, so a first submission three days before a launch date is a real risk.

Typically $30,000–$70,000 over the equivalent single-tenant product, and considerably more if you retrofit it. The cost is not a tenant column on your tables — it is that every query, cache key, background job, export and test must be tenant-aware, and that a single missed filter is a data breach rather than a bug. That raises your security and QA bar permanently. Design for it from the start even if you launch with one customer.

When a deal depends on it, not before — but design so you can. SAML SSO, SCIM provisioning, audit logs and role granularity total $80,000–$180,000 of engineering, and SOC 2 Type II adds $20,000–$45,000 in auditor fees on top of the evidence work. Building it speculatively is premature. Building your auth layer and data model so it can be added without a rewrite costs almost nothing and saves a painful quarter later.
