Someone will eventually ask you “how much does an app cost,” and the honest answer is a range so wide it’s useless: $15,000 to $250,000. That range exists because most quotes bundle unknowns into a single number and hope you don’t ask what’s inside it. We built Crumb Count end to end, and rather than give you another range, here’s what actually went into it, phase by phase, so you have a real reference point instead of a guess.

Where the budget actually goes

Every app budget breaks into the same handful of buckets, regardless of what the app does. What varies is how much weight each one carries. On Crumb Count, the split looked roughly like this:

  • Product definition and scope-locking. Before any code, we wrote down exactly what version one would and wouldn’t do. This is the phase most founders skip or rush, and it’s the single biggest predictor of whether a build stays on budget. Undefined scope is where quotes quietly balloon.
  • Core app build (Flutter, cross-platform). This was the largest line item by far, the actual screens, state management, data model, and the logic that makes the app do its one job well. Because it’s Flutter, the same codebase shipped to iOS and Android, which is the main reason the number wasn’t double what you’d expect.
  • Native integration work. Certain features don’t behave correctly through cross-platform abstractions alone, camera handling and platform-specific permissions being common culprits. That’s where native Swift and Kotlin work came in, applied only where the abstraction genuinely broke down, not as a blanket “let’s go native” decision.
  • Backend and admin console. A mobile app that stores or syncs anything needs a server behind it and a way for the founder to actually see and manage that data without opening a database console. This bucket is easy to underestimate because it’s invisible to a user tapping through the app, but it’s often a third of the real engineering effort.
  • QA, store submission, and the unglamorous last mile. App Store and Play Store review cycles, device testing across screen sizes, and fixing the ten small things that only show up when a real person who isn’t you uses the app. Founders consistently underbudget this phase; it’s rarely dramatic, but it’s rarely fast either.

Why the number is lower than a typical agency quote

Two things kept Crumb Count’s cost down without cutting corners, and both are structural, not effort-related tricks.

First, there’s no account manager, no project coordinator, and no layer of communication between you and the people writing the code. At a two-founder consultancy, the people quoting the work are the people doing it. Every hour billed at a larger agency to “keep everyone in sync” doesn’t exist here because there’s no one to sync with beyond the two of us and the client.

Second, Flutter’s cross-platform model meant one build effort instead of two parallel native ones, with native Swift/Kotlin reserved for the specific spots where it earned its cost. A lot of agencies either quote full native development for both platforms by default, or oversell “one codebase, zero tradeoffs” and then quietly bill you for the native workarounds later. We priced the native work in from the start, because we knew where it would be needed.

None of this means cheap. It means the price reflects the actual work, not overhead layered on top of it.

What moves the number up or down

If you’re pricing your own build against this, the variables that matter most are:

  1. How settled your scope is before day one. A founder who can describe the app in specific, bounded terms will spend less than one who wants to “figure it out as we go.” Figuring it out as you go is fine, it’s just a different, more expensive kind of project.
  2. Whether the backend is simple CRUD or something with real logic. Storing and displaying data costs a fraction of what building matching algorithms, real-time sync, or payment logic costs, which is part of why Kompete, with its head-to-head matching, sat at a different budget tier than Crumb Count.
  3. How much of the UI is standard versus custom. Standard forms, lists, and settings screens are fast. Custom animations, gesture-driven interactions, or bespoke data visualizations are not, and they should be flagged as such in scope, not discovered in week six.

The honest timeline question

Timelines get padded the same way costs do, usually to cover uncertainty the studio doesn’t want to admit to. A tightly scoped single-purpose app like Crumb Count moves through definition, build, and store submission in a matter of weeks, not months, precisely because the scope didn’t move once work started. The moment scope changes mid-build, the timeline stops being a promise and becomes a negotiation. The way to avoid that isn’t a longer buffer, it’s a shorter, better-defined version one.

If you’re staring at a quote right now and can’t tell what’s actually driving the number, that’s usually a sign the scope underneath it hasn’t been pinned down yet. That’s the conversation we have with every founder before any code gets written, at orithLabs, before you get a number, you get a scope you can hold us to.
