As answered by people managing https://open-gpt.app/ and Reorbit.app.
Reorbit.app's answer:
Most loyalty and review apps reserve features like VIP tiers, referrals and Google review syndication for their higher-priced plans, and most stores need two or three separate apps to cover loyalty, reviews and referrals. Reorbit includes all of it in one app, free for founding merchants. It also works with the email tool you already use: Klaviyo or Omnisend sends the messages from your own flows and templates.
Reorbit.app's answer:
Reorbit puts loyalty, reviews and referrals in one Shopify app with every feature included: no tiers, no feature gating, no add-ons. Because it's one system, the pieces work together: customers earn points for reviews, and one weekly message limit applies across loyalty, referrals and review requests, so shoppers aren't over-messaged by three separate tools.
Reorbit.app's answer:
Shopify merchants with fewer than about 10,000 orders a month who use Klaviyo or Omnisend for email and want loyalty, reviews and referrals without paying for several apps or upgrading to enterprise plans.
Reorbit.app's answer:
Early in my ecommerce career I was handed the spec for a new pricing model: feature gating, volume tiers, add-ons, top-ups. I remember thinking: why does this need to be so complicated and expensive? It turns out it doesn't. Reorbit started from that idea: one app for the retention tools a Shopify store actually needs, with every feature included. It's built by Reorbit Labs OÜ in Tallinn, Estonia, and launched on the Shopify App Store in September 2026.
Reorbit.app's answer:
TypeScript and Node.js with Fastify for the backend services, PostgreSQL, and AWS (ECS, SQS, RDS and Lambda). The merchant admin and storefront use Shopify's app extensions, including checkout and customer account extensions, plus Shopify Flow. Integrations with Klaviyo and Omnisend.
