Your customer's phone matters more than your AR feature. That sounds obvious. Most stores ignore it.
Apple built AR into iOS years ago, so iPhone AR apps tend to be polished and consistent. Android works well on flagships and gets patchy on cheap phones, which is a real consideration if your customers are not all on premium devices.
The famous ones cover both. IKEA Place runs on iOS and Android and is still the furniture reference: true-to-scale placement, dead simple. Amazon's View in Your Room lives inside the Amazon app on both platforms, which removes the biggest adoption hurdle of all. Nobody downloads anything new.
Then there is the web route, which skips the app question entirely. Shopify's native 3D and AR support renders right in the mobile browser. No install, no platform split, no maintenance. For a store owner, that is worth weighing against any native app.
When comparing, I would check four things. One, does it run on the phones your customers actually carry, not just the reviewer's flagship. Two, does AR launch in one tap or after a tutorial nobody finishes. Three, can you measure it. An AR ROI calculator app for iOS or Android models the case, and a mobile app to measure AR performance tells you the truth after launch. Four, if it is an AR Shopify plugin app, read real store reviews, because platform fit matters more than feature lists.
No single app wins for every store. The best one is the one your customers will actually open, on the phones they actually own.
