One app store link for your React Native app

Open and share the link

With one Jumper link, the store button needs no Platform.OS check and no pair of store addresses. The same constant goes into your share sheet, so a friend on Android gets Google Play even when you share from an iPhone.

import { Linking, Share } from 'react-native';

/** Your Jumper link: the App Store on iPhone, Google Play on Android, your site elsewhere. */
export const APP_LINK = 'https://oxi.cc/urapp';

export async function openStore() {
  await Linking.openURL(APP_LINK);
}

/** One link for iPhone and Android friends. */
export async function shareApp() {
  await Share.share({ message: `Get the app: ${APP_LINK}` });
}

Read the Google Play referrer

Optional, Android only: Apple gives apps no referrer, so iPhone campaigns are read in App Store Connect. This uses react-native-play-install-referrer and splits the query by hand, because React Native’s own URLSearchParams has not always implemented get. In Expo, add it to a development build.

// npm install react-native-play-install-referrer
import { Platform } from 'react-native';
import { PlayInstallReferrer } from 'react-native-play-install-referrer';

function parseQuery(raw: string): Record<string, string> {
  const out: Record<string, string> = {};
  for (const pair of raw.split('&')) {
    const [key, value = ''] = pair.split('=');
    if (key) out[decodeURIComponent(key)] = decodeURIComponent(value.replace(/\+/g, ' '));
  }
  return out;
}

/** Calls back with the Jumper link id and campaign, or null. Android only. */
export function readJumperReferrer(onResult: (r: { link: string; campaign: string | null } | null) => void) {
  if (Platform.OS !== 'android') return onResult(null);
  PlayInstallReferrer.getInstallReferrerInfo((info, error) => {
    if (error || !info?.installReferrer) return onResult(null);
    const query = parseQuery(info.installReferrer);
    onResult(query.jumper ? { link: query.jumper, campaign: query.utm_campaign ?? null } : null);
  });
}

Privacy policy, terms and support pages

Both stores ask for a privacy policy link before they accept your app, and Apple also asks for a support link. With Jumper.to you write or paste each page as plain text (or upload a .md file) and get an address like oxi.cc/<your link>/privacy-policy. Pages are text only: headings, lists, tables and links, no images or scripts. Each page uses one credit, like a link. Paste the privacy policy address in App Store Connect and Google Play Console before you submit.
