How to make one QR code for both iPhone and Android app downloads

QR codes are one of the best ways to get app installs from the real world: posters, flyers, restaurant tables, packaging, event badges and shop windows. But there's a catch. A QR code holds one link, and your app lives in two stores.

Here's how to make one QR code that works for everyone.

The problem with store links in QR codes

If you put your App Store link in the QR code, Android users who scan it land on a page they can't use. Put your Google Play link in it, and iPhone users hit a dead end. Printing two QR codes side by side works, but it asks people to figure out which one is theirs, and many won't bother.

The fix: a QR code that points to a smart link

Instead of a store link, put a smart link in the QR code. When someone scans it:

• An iPhone opens your App Store page.
• An Android phone opens your Google Play page.
• Anything else opens your website or a page with both store buttons.

One code, printed once, works for every phone.

Step by step

1. Create your smart link. Paste your App Store and Google Play links into Smart App Link. You'll get a short link like your-site.com/r/your-app.
2. Generate the QR code. Use any QR code generator and paste your smart link as the URL.
3. Pick a static QR code. Some generators make "dynamic" codes that route through their own servers and stop working when a free trial ends. A static code stores your link directly, so it never expires.
4. Test it on both phones before you print anything.

Printing tips so it scans every time

Keep it big enough. Around 2 × 2 cm (0.8 × 0.8 in) is a common minimum for something held in the hand. For posters people will scan from a distance, go much bigger.

Leave a quiet zone. Keep a clear white border around the code. Text or images touching the edges make it harder to scan.

Keep contrast high. Dark code on a light background works best. Avoid light-on-dark or low-contrast brand colors.

Shorter links scan better. A short smart link makes a simpler QR code with fewer, larger squares, which is easier for older phones to read.

Tell people what they'll get. A short line like "Scan to download the app" next to the code gets more scans than a code on its own.

Measure what's working

Because every scan goes through your smart link, you can see how many people opened it this month, and how many were on iPhone, Android or desktop. If you use different links for different posters or locations, you can see which one brings the most visitors.
