The short version

  • Only Flutter has a free tier, so it costs nothing to try first.
  • Each has a real cost: AppsFlyer pricing is per attributed conversion on an annual commitment, so a successful quarter raises the measurement bill in step with media spend and overage rates above the commitment are usually punitive.; Flutter dart is used almost nowhere else, so the language itself is a hiring and learning cost
  • They diverge on capability: AppsFlyer covers Multi touch install attribution, Flutter covers Single codebase, many targets.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

AppsFlyer

  • An app spending meaningfully on paid acquisition across several networks that need reconciling against one source of truthnot Flutter
  • Publishers who suspect they are paying for fraudulent installs and want them rejected before billingnot Flutter
  • Teams that must move event level marketing data into a warehouse for their own modellingnot Flutter
  • Apps running deferred deep links from web, email and social into specific in app contentnot Flutter

Flutter

  • Shipping one app to iOS and Android with a small teamnot AppsFlyer
  • Interfaces with heavy custom design that need to look identical on both platformsnot AppsFlyer
  • Adding web or desktop builds to an existing mobile codebasenot AppsFlyer
  • Prototyping quickly where hot reload shortens the design loopnot AppsFlyer

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AppsFlyer

  • Pricing is per attributed conversion on an annual commitment, so a successful quarter raises the measurement bill in step with media spend and overage rates above the commitment are usually punitive.
  • iOS attribution lost genuine capability when App Tracking Transparency arrived, and a good deal of what the interface now shows is modelled rather than observed, which the reports do not always make obvious.
  • The headline price covers attribution only; deep linking, fraud protection, audiences and raw data export are separate modules, so the quoted figure and the invoice differ substantially.
  • Self attributing networks such as Meta and Google report their own numbers, and reconciling those against AppsFlyer is ongoing work that no vendor eliminates.
  • Historic attribution data does not transfer between measurement partners, so switching vendors resets year on year comparisons and effectively locks in the incumbent after a couple of years.

Flutter

  • Dart is used almost nowhere else, so the language itself is a hiring and learning cost
  • Because Flutter draws its own widgets, apps can feel subtly unlike the platform unless deliberately styled per-platform
  • Binary sizes are larger than equivalent native apps because the engine ships with the app
  • Access to a brand-new platform API waits on a plugin, or on writing platform channel code yourself

Answered from the vendors’ own pages

AppsFlyer: How is it priced?

Per attributed conversion against an annual commitment, plus separate fees for the additional modules. Negotiate the commitment carefully.

Flutter: Is Flutter free?

Yes. Flutter is open source with no licence fee. The framework is under a Creative Commons Attribution 4.0 licence and its code samples under the 3-Clause BSD licence.

AppsFlyer: Did App Tracking Transparency break attribution?

It removed deterministic device level attribution for users who decline tracking. What remains on iOS is aggregated and delayed, and vendors fill the gap with modelling.

Flutter: What language does Flutter use?

Dart, a language Google designed for fast startup and ahead-of-time compilation to native code.

AppsFlyer: Can we take our data if we leave?

You can export raw data while under contract. Attribution history itself does not migrate to another vendor.

Flutter: Can Flutter build for more than mobile?

Yes. The same codebase targets iOS, Android, web, Windows, macOS, Linux and embedded devices, though mobile remains the most mature target.

Flutter: How is Flutter different from React Native?

Flutter draws its own widgets with its own engine, so the result is pixel-identical across platforms. React Native renders to the real native components of each platform. Flutter uses Dart; React Native uses JavaScript and React.
