We build the first one
Fixed scope, deadline in the contract, and success targets defined together with you before the first line of code.
Novais guarantee · written into the contract
We build your app.
If it doesn't take off,
the second one is on us.
Software engineering from people who sign every delivery. You talk directly to whoever writes the code — from the first assessment to the app live on the store.

The second-delivery guarantee
No one gives back the time lost on an app that never landed. We give back the work.
Every idea carries market risk — and that risk usually lands entirely on the client. Here it is shared: if the first app doesn't hit the targets we agreed in writing before starting, we build the second one at no development cost.
02
You take it to market
App published on the stores and 90 days of operation with the launch plan we agreed on. We track the numbers with you.
03
Didn't take off? The second is on us
We build a new project of equivalent scope and complexity, at no development cost. A real second chance.
Guarantee terms — read before you sign
- Valid for projects with a signed fixed scope, from the minimum plan defined in the commercial proposal onwards.
- Success targets (installs, sign-ups, revenue or usage, as applicable) are defined jointly and recorded in the contract before development begins.
- The second project has scope, timeline and complexity equivalent to the first, capped at the same contracted hours.
- The app must have been published and kept in operation for at least 90 days, with the agreed launch plan actually carried out.
- Third-party costs are not covered: store fees, servers, domains, licences, payment gateways and paid media.
- One guarantee per client, claimable within 30 days after the end of the evaluation period.
- Does not apply to projects halted by the client, with unilaterally changed scope, or with outstanding payments.
The full terms are part of the service agreement and are presented together with the proposal, before any signature. No last-minute fine print.
What we build
Software built to run in production, not to impress in a demo.
We work with a limited number of clients at a time. That is what lets us respond fast and know your product inside out.
Mobile apps
iOS and Android from a single codebase, with native performance and store publishing included.
- Flutter, React Native, Swift and Kotlin
- App Store and Google Play publishing
- Push notifications and offline mode
Web systems and APIs
The engine behind the product: backend, integrations, admin panels and the reports your team uses every day.
- TypeScript, Node and PostgreSQL
- Payment gateway integrations
- Admin panels and internal automation
Consulting and architecture
For when the project has stalled, cloud costs have exploded, or the team needs to decide the next step with someone who has been there.
- Code and architecture review
- Rescuing stalled projects
- Stack choice and scaling plan
Continuous evolution
After delivery the app stays alive. New features, fixes and monitoring under a predictable monthly contract.
- Fortnightly improvement cycles
- Monitoring and alerting
- Support with an agreed response time
How we work
Four stages. No surprises halfway through.
-
01
Assessment call
We get to grips with the idea, the audience and — above all — what "working" actually means in your case.
30 min · free -
02
Scope and proposal
Screens, timeline, fixed price and the guarantee targets, all in writing before any payment.
within 3 business days -
03
Building in cycles
You see the app running from the very first fortnight. The scope we signed is followed to the letter, start to finish.
2-week cycles -
04
Launch and follow-up
We handle store publishing and monitoring, and stay close throughout the guarantee period.
90 days included
How we take on the work
The contract guarantees the deadline. Reputation guarantees the rest.
When your name is on the door, a delivery stops being a contract and becomes reputation. That is why the person who takes the first call is the one who writes the code, not a salesperson who disappears after signing.
We don't hand projects to third parties, we don't swap the team halfway through, and we don't ship a system we wouldn't maintain ourselves.
Novais Software engineering since the very first client
Fixed price
The price agreed in the proposal doesn't change mid-project. Scope changes are quoted separately, with your approval.
The code is yours
Repository, store accounts and credentials in your name from day one. You are never locked in to us.
No outsourcing
Whoever talks to you is whoever builds it. No reselling the project, no ghost team.
Deadline in writing
Delivery date in the contract and visible progress every 15 days, with a live demo.
Frequently asked questions
The questions everyone asks in the first conversation.
How much does it cost to build an app?
It depends on scope — a simple booking app and a marketplace with payments don't cost the same. That's why the assessment is free: in 30 minutes we can indicate the investment range and the timeline before you spend anything. The proposal comes with a fixed price, not an hourly rate.
How long until my app is ready?
A first publishable version usually takes 8 to 14 weeks. You don't wait until the end to see something: every two weeks there is a working delivery to test on your own phone.
How does the guarantee work in practice?
Before we start, we define together what success means for your app and record it in the contract. The app is published and runs for 90 days with the agreed launch plan. If the targets aren't met, you claim the guarantee within 30 days and we build a second project of equivalent scope, at no development cost.
The full terms are listed in the guarantee section and in the contract.
Do I need a finished plan before talking to you?
No. Most of our clients arrive with an idea and a few notes. Turning that into scope, screens and priorities is part of our job — and that is precisely where most of the waste is avoided.
Do you sign non-disclosure agreements?
Yes, and without bureaucracy. If you prefer, we sign the NDA before the assessment call even happens. Your idea is yours.
Which technologies do you work with?
Flutter, React Native, Swift and Kotlin on the app side; TypeScript, Node and PostgreSQL on the server; integrations with the main payment providers. We choose mature technology with professionals available on the market — so you can change supplier one day if you want to.
What if I already have an app and just want to improve it?
We do code and architecture reviews, take over maintenance of existing systems and rescue stalled projects. In those cases the first step is a technical assessment with a report on what stands and what needs rebuilding.
