What we build for clients

Every client project gets the same standards we hold our own products to. Quoted per project, with a fixed price agreed before work begins.

  • Mobile apps

    Native iOS apps, designed and built by the team behind Fe2. From the first prototype through App Store review, and the updates that follow.

  • Web apps

    Booking systems, client portals, dashboards, and internal tools, shaped around how your business runs instead of forced into off-the-shelf software.

  • Websites

    Fast, well-designed sites that load quickly, show up in search, and make it easy for customers to get in touch.

    See website packages

  • Support after launch

    Hosting, updates, fixes, and new features once you're live, so what we build keeps working and keeps improving.

How a project runs

The same process we use on our own products. No surprises on price, and you see real progress every step of the way.

  1. Step 01

    Scope

    A call or two to understand the problem, then a written scope with a fixed price and timeline. You know exactly what you're getting before work starts.

  2. Step 02

    Design

    We design the key screens first and walk you through them, so changes happen while they're still cheap to make.

  3. Step 03

    Build

    You get working builds to try on your own phone or browser as we go, not just status updates.

  4. Step 04

    Launch & support

    We handle App Store submission or go-live, then stay on for fixes, updates, and whatever comes next.

Who you'll work with

A studio that ships its own software, so client work comes with first-hand experience of launching and running a real product.

How we work
Founder-led, with specialists as needed

NIVIS is a software studio in Toronto. We design, build, and run our own products, starting with Fe2, and build apps and websites for other businesses.

Building our own apps keeps us honest: we deal with real users, App Store reviews, and the long tail of updates after launch. Client projects get that same experience, led by me from the first call to launch, with specialists brought in as each project needs.

Common questions

If something isn't covered here, ask. We're happy to talk it through.

How much does an app cost?
It depends on scope, so every app is quoted individually. After a short call you'll get a written scope with a fixed price and timeline, before any work begins.
How long does a project take?
Most websites are live in about two weeks. Apps depend on scope; your written scope includes a schedule with milestones, so you'll know the launch date up front.
Have you shipped apps of your own?
Yes. We designed and built Fe2, a training and nutrition app on the App Store, and we run it ourselves. Client apps get the same process and standards.
I only have an idea. Is that enough to start?
Yes, many projects start there. We'll help you work out what the first version needs and what can wait, so you launch sooner and spend less.
Do I own what you build for me?
Yes. The code, designs, accounts, and domain are yours. Apps are published under your own developer account, and there's no lock-in.
Can you work on an existing app or website?
Often, yes. We'll review what you have and tell you honestly whether it's worth improving or better to rebuild.
What happens after launch?
We offer month-to-month support for hosting, updates, fixes, and new features. There's no long-term contract, and you can cancel anytime.

Have something you want built?

An app, a website, or just an idea. Tell us what you're working on and we'll reply within one business day.
