Replace Amplitude: smaller app

Q: How much do these SDKs typically add to my binary?

Varies by SDK. The cleanest way to see for your specific app is to build the release AAB twice — once with the SDK, once without — and diff the artefact sizes. Google's Android App Bundle Explorer or `bundletool` does this directly. Order-of-magnitude on a fresh Android app: heavy attribution SDKs and Firebase Analytics each add several megabytes once you account for transitive dependencies; lighter SDKs that ship as a single thin library may add a few hundred KB once shared deps are de-duplicated.

Q: Does binary size actually affect downloads?

Yes — particularly past Apple's 200 MB cellular-download cap and on lower-end Android devices with limited storage. Google's Play Console has internal metrics showing measurable install-rate differences when AAB size crosses common thresholds (50 MB, 100 MB).

Q: How does the size reduction work in practice?

Removing a single ~3 MB SDK from your release build shrinks the binary by roughly that amount. Multiplied by user installs, the cellular-data savings compound. iOS App Thinning handles per-device variants; Android AAB delivers size-optimised installs by ABI / density / language.

Q: Does the smaller SDK come at a feature cost?

Respectlytics intentionally doesn't bundle features it considers separate concerns: no ads, no attribution, no in-app messaging, no A/B testing, no crash reporting. Each of those is a dedicated tool's job. The smaller surface is the deliberate design — you add only what you actually use.

▸Example Amplitude call (the "before")

js Respectlytics

import { Amplitude } from '@amplitude/analytics-react-native';

await Amplitude.init('YOUR_API_KEY', userId, {
  trackingOptions: { ipAddress: true, language: true, platform: true },
});

await Amplitude.identify({
  email: email,
  plan: 'pro',
});

await Amplitude.track('Paywall Purchase', { value: price, currency: 'USD' });

App-binary size affects download conversion (especially on lower-end devices and cellular networks) and storage pressure for users with full phones. Heavy analytics SDKs (Firebase Analytics, AppsFlyer, Branch) routinely add several MB to the binary; Respectlytics's per-platform SDK is under 100 KB.

☑Remove Amplitude cleanly

1
Remove the Amplitude SDK from your build (CocoaPods / SPM / Gradle / npm / pub)
2
Remove Amplitude.initialize(...) and track(...) call sites — replace with Respectlytics.configure() and Respectlytics.track("event_name")
3
Audit for Identify operation usage — those set per-user properties; remove them
4
If you used Amplitude Experiment for feature flags, plan a separate migration (e.g., GrowthBook or LaunchDarkly) — Respectlytics is analytics, not flagging
5
Confirm IDFA / AAID surfaces in your Info.plist + AndroidManifest are no longer needed by other SDKs before removing them

⇋Amplitude vs Respectlytics — smaller app binary
