Constantly having to sign in, very tedious. would like to request two modification to it… After clearing the search bar (X) the app should automatically put the cursor back in th…” (1★, v4.0.0, 2026-10-01, GB)
2. Fix in-use crashes and freezes: 22 of 220 1–3★ reviews. What to do: Match quoted actions to crash reports; ship a hotfix for the top stack trace.
   “The in store shop and scan function is a major downgrade from the old dedicated shopping app. This version is painfully slow and freezes often. On my last visit it failed to send the shop to the till and crashed it, meaning i had to scan everything manually. Won’t be using it aga…” (1★, v4.0.0, 2026-09-27, GB)
3. Ship the most requested feature: 22 of 220 1–3★ reviews. What to do: Read the quotes below for the exact request; consider a public roadmap.
   “If I could give this 0 stars I would. It’s almost as if the app developer is trying to force people not to use the smart shop function. Awful functionality with the iPhone camera. Hit and miss if the app loads properly. After the latest update where a beep was added when an ite…” (1★, v3.67.0, 2026-09-08, GB)
4. Speed up loading: 17 of 220 1–3★ reviews. What to do: Profile cold start and the slowest screens on older devices; cache content.
   “I have experienced lots of issues with the App for the last few weeks.

These issues have been consistent for a few weeks.…” (1★, v3.56.0, 2026-04-25, GB)
5. Make trials and renewals transparent: 16 of 220 1–3★ reviews. What to do: Show the renewal date and price before the trial ends; link to cancellation. Surprise charges drive 1-star reviews and refunds.
   “The chop chop service was terrible. Supposed to be <60 mins, but 90 mins after ordering with nothing having arrived and they cancelled our order.

   “The SmartShop app was really good, but now the feature has been moved into the Sainsbury’s app and redesigned so that it is completely counterintuitive. Why do I have to give my location and scan an on site qr code? Why does the scan function just continually repeating the same s…” (1★, v4.0.0, 2026-09-27, GB)

Method and limits

Reviews were collected once from Apple's public customer-reviews feed (most recent first; UK, Ireland, Germany, France, Spain, Italy, Poland and Netherlands storefronts merged, 2 with reviews; up to 300 reviews). Star, month and version figures are plain counts of that sample. Theme and issue figures come from fixed keyword patterns (for example “subscription”, “charged”, “refund” for pricing) run on English-language 1–3★ reviews from the UK and Irish stores only (reviews in other languages count in the star, month and version figures but not in the themes); a keyword match is not a judgement of the review, so check the quotes. The paid report classifies every review with an AI model into 7 themes and 18 issues with severity. This is a snapshot of recent reviews, not the app's full history. Generated 24 October 2026.
