Build, buy or rebuild. How to build, rebuild or relaunch a dating app.

Before a dating app launches it needs a privacy policy and terms, age gating, UK and EU safety processes, filtering, reporting and blocking for Apple and Google, in-app account deletion, store billing, a staffed moderation queue, enough members in launch areas, and a short list of metrics. This checklist sets out each step with its source, checked on 16 October 2026.

Published agency estimates put a dating app build at roughly $15,000 to $80,000 for a basic first version and $150,000 to $600,000 for a Tinder-scale product. The bigger number is running it: in our illustrative example, a 300,000-member app costs about $107,000 a month before app store fees.

To migrate a dating app without losing members, keep the same App Store and Google Play listing, carry over every profile, photo, match, message, block and report, and keep subscriptions inside the same app record. Release in stages, keep the old backend running until the new one is proven, and tell members what is changing before they see it.

EliteSingles closed on 30 April 2026 after its operator, Spark Networks, went into insolvency, and members lost their accounts and messages. It relaunched in September under SuccessfulMatch with a new member database. The lesson for buyers: the domain and name transfer easily, but members, store listings and subscriptions only survive if you plan for them.

A dating app needs a rebuild when its technology stops it doing the basics: shipping updates every few weeks, passing store review, keeping crashes under Google Play's thresholds, adding verification, taking payments reliably and meeting new law. One sign can be fixed. Several at once, plus dependence on one or two engineers, usually means the platform itself is the problem.

A dating app needs ten backend systems working together: accounts, profiles and photos, discovery and matching, messaging, moderation, ID and age checks, payments, notifications, analytics and compliance. The app screens are the visible part. Most launch delays, store rejections and safety failures trace back to one of these systems being missing or thin.
