▸Example Branch call (the "before")
import BranchSDK
Branch.getInstance().initSession(launchOptions: launchOptions) { params, error in
// Branch fingerprint + IDFA matching happens here.
if let referringLink = params?["~referring_link"] as? String {
// Route the user based on the deep link...
}
}
Branch.getInstance().userCompletedAction("Paywall Purchase", withState: [
BranchStandardEventTransactionId: orderId,
"revenue": price,
])
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 Branch cleanly
-
1
Remove Branch from your build (
Branch/io.branch.sdk.android:library/react-native-branch/flutter_branch_sdk) -
2
Remove
Branch.getInstance().initSession(...)anduserCompletedAction(...)call sites -
3
Decide what replaces Branch's deep-link routing — Universal Links + App Links are first-party alternatives (no SDK; OS-handled)
-
4
Remove Branch URL schemes from your
Info.plistandAndroidManifest.xml -
5
Delete the Branch app dashboard entry once events stop flowing
⇋Branch vs Respectlytics — smaller app binary
| Branch | Respectlytics | |
|---|---|---|
| Typical contribution to IPA size | — see tool note above | < 100 KB |
| Typical contribution to APK / AAB size | — see tool note above | < 100 KB |
| Transitive dependencies | — see tool note above | None (zero third-party) |
❓Frequently asked questions
How much do these SDKs typically add to my binary?
Varies by SDK. Rough order of magnitude on Android (release AAB): Firebase Analytics ~3-4 MB (with transitive Google Play Services), AppsFlyer ~1-2 MB, Branch ~1.5 MB, Mixpanel ~1 MB. Our [SDK Bundle-Size Comparator](/tools/sdk-bundle-size-comparator/) has up-to-date numbers per SDK.
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).
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.
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.
