 "summary": "Free Shopify app from Effectify that adds a customizable floating back-to-top button and, optionally, infinite scroll on collection pages, with no code and no paid tier. The button is a safe convenience; the infinite scroll replaces the paginated collection URLs crawlers use, so it is a merchandising decision rather than a styling one.",
 "best_for": "Shopify merchants who want a free, one-click back-to-top button on long collection and product pages without touching theme code — and who can treat infinite scroll as a separate $2.99-a-month decision rather than part of the same install",
 "skip_if": "you run a large catalogue that depends on paginated collection URLs being crawled, your theme already ships its own load-more or filtering behaviour, or you need conversion work rather than navigation polish — this only changes how the page scrolls",
 "honest_knock": "The two features carry very different risk, the app presents them as one install, and since August the money has been split across them in a way the name does not warn you about. Infinite scroll replaces the paginated collection URLs a crawler uses to walk a large catalogue, pushes your footer permanently out of reach, and on some themes collides with the load-more or filtering logic already in the theme — that is a merchandising decision, not a styling toggle. The app also edits Online Store script tags and the theme, so it adds a third-party script to every page and an uninstall can leave remnants.\n\nWhat changed is which half you pay for. Read on 19 September 2026, the free plan keeps the scroll-to-top button and infinite scroll sits on the $2.99 Unlimited plan, where on 25 August the whole app was free. The amount is trivial; the shape is not. The half that can quietly alter how your collection pages are crawled is now the half with a billing relationship behind it, and the seven-day trial is the only window in which you will find out what it does to your store before the charge starts. Anything written about this app before September — including a free-forever recommendation — describes an install that no longer exists.",

  "notes": "(read 2026-08-25 and re-read 2026-09-19 on apps.shopify.com/custom-scroll-to-top) Two plans now, where there was one. On 25 August 2026 the listing carried no paid tier, no usage meter and no surcharge — the pricing block most App Store listings use to sell an upgrade was simply absent. On 19 September 2026 it carries a Free Plan and an Unlimited Plan at $2.99 a month, or $25.11 a year with a 30% saving and a 7-day free trial. The split does not fall where the app’s name suggests. Free keeps the scroll-to-top button and its styling: multiple presets, button colour and hover colour, and the option to hide it on the mobile storefront. Unlimited adds infinite scrolling and the load-more button, plus uploading your own SVG icon for the button. So the feature the app is named after, and the one the first three of the listing’s five selling points describe, is now the paid half. All charges are billed in USD every 30 days. The app has been on the App Store since March 2020, carries Shopify’s Built for Shopify badge — the store’s own bar for performance, design and integration — and the listing names eleven interface languages.",
