Pricing signals
Ways to work together.
Exact numbers depend on scope. You’ll get ranges before you commit — never a surprise invoice.
Fixed-price MVP
Defined scope and timeline after discovery. Most MVPs land in a mid four- to five-figure range depending on features and integrations.
Monthly retainer
Ongoing support, improvements, and bug fixing for live products. Retainers start from a monthly support plan sized to your release cadence.
Hourly / rescue
Targeted help for upgrades, crashes, store rejections, and unfinished features — billed hourly with a clear estimate before work starts.
About
A studio built for shipped products, not slide decks.
TrioNative Solutions designs and builds websites and native mobile apps. Every engagement has a dedicated technical lead. We’re remote-first with working hours that typically overlap EU and US mornings (UTC+5).
Why TrioNative
We specialise in React Native and web products for startups and product teams — with honest scoping before we write a line of code.
How we work
We tell you early what’s feasible, what it costs, and how long it takes. You own the code. We stay available after launch.
Who we help
Founders shipping an MVP, teams modernising an existing app, and companies that need store releases, AI features, or rescue work.
FAQ
Straight answers.
Who owns the code?
You do. Repositories, store accounts (when you provide them), and deliverables are transferred to you. We don't lock you into proprietary tooling — that matches our "code you own" promise.
Can you work under NDA?
Yes. We're comfortable signing NDAs before reviewing sensitive product details.
How long does a typical MVP take?
Most mobile MVPs land in 6–8 weeks. Smaller features often take 2–3 weeks. You'll get a phase-by-phase timeline in discovery.
What happens after launch?
You can continue on a retainer for updates and bug fixing, or request ad-hoc support. Handover docs are included either way.
How do you handle change requests?
Changes are written down with impact on timeline and cost before work continues — no silent scope creep.
What if the timeline slips?
We'll flag risk early, explain the cause, and propose options: reduce scope, extend timeline, or re-prioritise. No last-minute surprises.
Do you fix existing React Native / Expo apps?
Yes. App rescue & support is a core service — upgrades, crashes, store rejections, payments, and unfinished features. You can also request a free audit.
