AppRanks verdict
Generated from live marketplace data — refreshed daily
Letters｜友人・知人への紹介＆口コミを広げて売上アップ is a highly rated Shopify app with a limited review volume. It is listed in the Affiliate program category on Shopify App Store, which AppRanks treats as the canonical taxonomy node for ranking and competitor comparison. 24 reviews put it in the early-traction tier — useful for early-stage stores willing to be on the leading edge. Early-traction review counts are sensitive to single launch periods or feature events, so a 30-day re-check before bigger commitments often resolves whether the trend is sustained. The free tier lets you trial the entry feature set without committing a payment method. AppRanks tracks rating, review count, pricing tier, and category position daily — the figures on this page reflect the most recent scrape from the canonical Shopify App Store listing.
