Apps for smarter online shopping

Four tools for three jobs: checking prices and coupons before you pay, planning outfits from clothes you own, and finding furniture by look. All four come from US companies and have English-only interfaces, so each entry states where it runs and what limits it. Phia and Pricifly cover the same price-check step: Phia leans on fashion, Pricifly on general marketplaces. Pick the steps you need; this is not a bundled purchase or a claim that the products integrate automatically.

Frequent online shoppers comfortable with English-only apps

Costs are not added up; every plan below is for individuals and priced in USD. Phia is free with no paid tier. Alta is free for now but publishes no future pricing or limits. Pricifly has a Free plan with 10 credits a month; its pricing page lists Starter at $4, Pro at $9 and Power at $19 per month, billed monthly, while its Chrome Web Store page says a 14-day trial then $7 per month. Onton has a Free plan with 10 images a month; Basic is $8, Plus $20 and Studio $35 per month, billed annually only.

   1. Phia – Price-check fashion before buying

   Compares fashion prices across 220,000+ sites including resale (per Phia), auto-applies coupons and sends price-drop alerts, for free. Runs as an iOS app (tap "Should I Buy This?" in Safari) and a Chrome extension; no Android app, English-only. Trade-off: In July 2026 Bloomberg and researcher Ben Edelman reported the extension claimed affiliate commissions on sales Phia did not refer. Phia acknowledged "misattributions", removed the features on 7 July 2026 and is reversing transactions; Impact.com suspended it. In August 2026 Bloomberg, citing internal messages, reported the co-founders had known since December 2025. No regulator or court action was found. Separately, Fortune reported in 2025 that an earlier extension uploaded the HTML of opened pages; Phia removed that, and the current version still logs URLs

   2. Pricifly – Compare prices and test codes on big marketplaces

   A Chrome extension that compares total price including shipping and tests coupon codes at checkout; the homepage says it detects products on Amazon, eBay, Walmart, Target, Best Buy, Etsy, AliExpress and Shopify stores. The extension is Chrome-only (with a web portal) and English-only; the Free plan needs no card. Trade-off: Launched in 2026, it shows 7 users and 1 rating on the Chrome Web Store. Website and Chrome Web Store prices differ, and the store's privacy section lists location and web history as handled data, which conflicts with the vendor's policy

   3. Alta – Plan outfits from what you own

   A free digital closet: add items by photo or forwarded receipt email, get outfits based on weather and calendar, track cost per wear and get wishlist price-drop alerts. Available on iOS, Android and the web. Trade-off: The policy covers US residents only and the interface is English-only. It collects location, height, body shape and photos and lets third-party ad partners place trackers (the policy names Meta Pixel); Alta has not said how it will charge in future

   4. Onton – Find furniture by look

   Search furniture and decor by description or reference photo, pick an item inside an image, arrange choices on a canvas and generate room images with AI. The Free plan needs no card. Trade-off: Web only and English-only, with no App Store or Google Play app. Its accuracy lead over Amazon and Google Shopping comes from its own 90-query benchmark judged by AI models, not independently verified; no refund policy is published
