▸Example mParticle call (the "before")
import mParticle_Apple_SDK
let options = MParticleOptions(key: "YOUR_KEY", secret: "YOUR_SECRET")
options.identifyRequest = MPIdentityApiRequest.withEmptyUser()
options.identifyRequest?.email = email
options.identifyRequest?.customerId = userId
MParticle.sharedInstance().start(with: options)
let event = MPEvent(name: "Paywall Purchase", type: .transaction)
event?.customAttributes = ["value": price, "currency": "USD"]
MParticle.sharedInstance().logEvent(event!)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 mParticle cleanly
-
1
Remove the mParticle SDK from your build (
mParticle-Apple-SDK/mparticle-android-sdk/react-native-mparticle/mparticle_flutter_sdk) -
2
Remove
MParticle.start()andMParticle.logEvent(...)call sites -
3
Critically: review your mParticle output forwarders and decide which downstream destinations you still need data flowing to (most don't — Respectlytics is direct)
-
4
Delete
Identity.identify()andmodify()calls — those drive the identity merge graph -
5
Delete the mParticle workspace's mobile input once events have stopped flowing
⇋mParticle vs Respectlytics — smaller app binary
| mParticle | 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.
