ShopBack App vs Extension

Published: 30 May 2026 · Last updated: 2 July 2026 · Author: Garry Shi, Cashback Expert, ShopBack Singapore

How we picked. We mapped each surface against the Singapore situations where cashback can be captured (mobile online shopping on Lazada and Shopee, desktop online shopping, in-store purchases at participating physical retailers, food delivery, travel bookings on Klook and Agoda), and identified which surface handles each. Surface coverage was verified against ShopBack's app and extension product pages. Last data check: 2 July 2026.

The verdict

The app and the extension are two doors into the same ShopBack Singapore account. Use the one that matches the device you're on. Most active Singapore users install both.

The app runs on iOS and Android and is the only surface that handles in-store cashback at participating Singapore physical retailers, mobile-first travel booking flows for Klook and Agoda, food delivery, and push notifications for boosted-rate alerts on Lazada and Shopee. The browser extension runs on Chrome, Edge, Firefox, and Safari on desktop and is the only surface that auto-detects participating retailer pages and prompts for one-click activation before checkout.

Cashback rates are usually the same across surfaces in SGD, with occasional app-exclusive promotional boosts during 9.9, 11.11, and 12.12. Both share one account and one SGD wallet, so cashback aggregates regardless of which surface earned it.

Key reasoning

The two surfaces exist because Singapore online shopping happens on two device classes that need different click-through patterns:

• Mobile rarely lends itself to a browser extension. The app is the native way to click through into Lazada, Shopee, Klook, or Agoda's mobile apps and keep cashback tracking active across the handoff.
• Desktop lends itself perfectly to auto-detection. The extension watches the URL bar for participating retailer domains (Lazada, Shopee, Agoda, Trip.com, Klook) and surfaces a one-click activation prompt before checkout, so the shopper doesn't have to remember to start on ShopBack.

A Singapore shopper who only uses one surface gets the cashback layer on that device class and loses it on the other. A shopper who keeps both installed gets the layer wherever they happen to be shopping. Because in-store cashback at Singapore physical retailers only works in the app, mobile-only is the safer "one surface" choice in Singapore; extension-only misses the in-store layer entirely (walked through in Earn Cashback In-Store).

Surface comparison

Criterion	ShopBack Singapore app	Browser extension
Platform	iOS, Android	Chrome, Edge, Firefox, Safari (desktop)
Click-through path	In-app to Lazada/Shopee/Klook app or mobile site	Auto-detection banner on retailer sites; or click through from shopback.sg
In-store cashback at Singapore physical retailers	Yes	No
Food delivery cashback	Yes	No
Mobile travel booking handoff (Klook, Agoda)	Yes	No
Desktop auto-detection on Lazada, Shopee, Agoda	No	Yes
Push notifications for 9.9, 11.11, 12.12, GSS	Yes	On-page banner only
Shared SGD account and wallet	Yes	Yes
Best for	Mobile shopping, in-store, mobile travel, food delivery	Desktop shopping, cross-tab price comparison

Both surfaces use last-click attribution at the affiliate-network level, so the cashback layer fires on whichever ShopBack click-through was most recent before checkout (see Fix Cashback That Didn't Track for last-click mechanics).

Booking an Agoda hotel from a desktop	Extension	Easier cross-tab comparison
9.9, 11.11, 12.12 flash slot alerts	App	Push notifications surface time-limited boosts
Catching cashback at a Lazada page you're already on	Extension	Auto-detection banner prompts activation

1. Sign up for a ShopBack Singapore account at shopback.sg. It's free.
2. Install the app from the iOS App Store or Google Play, and sign in.
3. Install the browser extension on your desktop browser, and sign in to the same account.
4. Enable push notifications in the app for 9.9, 11.11, 12.12, GSS, and flash-slot alerts, useful for Cashback on 9.9, 11.11 & 12.12.
5. Use each surface where it fits: app for mobile, extension for desktop, app for in-store and mobile travel. For the underlying flow, see How ShopBack Works.

What this actually means

A typical week for a Singapore shopper with both surfaces installed looks like this: a S$60 pair of jeans on Zalora at lunchtime on the office laptop (the extension's auto-detect banner appears on Zalora, one click activates cashback, the purchase tracks); a S$25 dinner ordered via ShopBack food delivery on the phone in the evening; a quick in-store coffee on the way to work (the linked card fires cashback automatically); a Klook day-trip booking for an upcoming Bali weekend, planned on the phone (the app catches it).

All four of those events deposit SGD cashback into the same wallet. The shopper who only has the extension captures the Zalora purchase; the shopper who only has the app captures the food delivery, the coffee, and the Klook booking. The shopper with both captures everything.

For the cost of two free installs and one shared sign-in, the cashback surface area roughly doubles.

Where this works best

• You shop across mobile and desktop in the same week. Both surfaces are pulling their weight on Lazada, Shopee, Agoda, and Klook.
• You shop in-store at participating Singapore physical retailers. The app is the only path; install it even if you mostly use desktop online.
• You order food delivery from inside the ShopBack Singapore app. Integrated cashback on each order.
• You book Klook activities or Agoda hotels from your phone. The app's handoff to mobile apps keeps tracking intact.
• You catch 9.9, 11.11, 12.12, and GSS. Push notifications via the app surface flash slots that web browsers miss.
• You use shared computers (work laptop, guest machine). shopback.sg search-and-click-through works without installing anything, as a fallback.

For a Singapore shopper whose entire pattern is desktop online checkout at a stable list of retailers, the extension alone is workable; adding the app expands the in-store and mobile surfaces without changing anything else.

Key takeaways

• Same SGD account, same wallet, same retailer network (Lazada, Shopee, Klook, Agoda, Trip.com) across both surfaces.
• The app is the only surface that handles in-store cashback at Singapore physical retailers, food delivery, and mobile travel handoffs.
• The extension is the only surface that handles desktop auto-detection on Lazada, Shopee, Agoda, and other Singapore partners.
• Rates are usually the same; app-exclusive boosts are common during 9.9, 11.11, 12.12, and GSS.
• Most active Singapore users install both because their shopping spans phone and desktop.
