“They reskinned a ready-made app for us, added our payment flow and published both stores in under three weeks. It felt like having an in-house team.”
“I have bought many apps; support is usually the weak point. Zynvonex answered every question with an actual solution — and the customization quality was above the original code.”
“We outsource our overflow mobile work to Zynvonex. Clean architecture, honest timelines, and builds that pass store review first try. Rare combination.”
“From a rough idea to a live app with ads and analytics — one team, one price, zero surprises. Already planning the second app with them.”
Practical writing on apps, marketing and AI — from a team that publishes its own products.
Yes. We publish complete, production-quality app source codes — games, fitness, e-learning and utility apps. You buy the licence, and we can customize and publish it for you as a service.
Absolutely. Bring any ready-made (or other) source code — we will audit it first, then reskin it, add the features you need, connect your own accounts and publish it under your brand.
A visual-only reskin typically takes 1–2 weeks. Reskin plus new features and store publishing usually lands in 3–5 weeks depending on scope.
Yes — including the annoying parts: data-safety forms, privacy labels, consent flows, content ratings and review responses. We maintain a 100% approval mindset and fix rejections at no extra cost.
That is our core service. We build Flutter, native and web products end to end — design, development, backend, monetization and launch.
