Great.

Launching, fixing, scaling — wherever you're stuck. We take over at any stage: clean up the code, stabilize, integrate, and scale further.

Most agencies deliver. Few stay involved.

We stick around from strategy to launch and support.

Need proper CRM or database integration?

We connect your app to systems, stable and in sync.

Excited to go live but short on time?

We meet your deadline while maintaining quality.

Outdated app? No docs,
no problem.

Update and evolve your product without specs.

Why do I even need an app?

Because your users are already on their phones.

When everyone, from clients to internal teams, clearly sees what’s going on, everything works faster
and more efficiently.

And sometimes, it’s simply more convenient
than a website.

Alex Rivers

CEO

Big thanks to the Toimi team! Everything was done thoughtfully, tastefully, and right on schedule. Loved how design and development were handled together — quick approvals, quick launch. Super easy to work with.

Karina Miller

Manager

We came in with a task tailored to our business — and everything was adapted to fit, no templates. What we appreciated most is that they didn’t just think about how to build it, but why. You can feel the care in their approach.

Mark Holzman

Manager

We ordered a webinar interface design and a couple of fintech-related things from Toimi — everything was on point. What stood out was that they didn’t just deliver, but also suggested ways to simplify. We took notes.

Maria Reed

CEO

We plan to continue working

What affects the timeline of mobile app development?

The scope of work, number of integrations, and how quickly you respond to our clarifications. We always leave room for final polishing and testing — so we hit the deadline and get things right.

How much does it cost to develop a mobile app?

It depends on the platform (iOS, Android, Flutter), functionality, and technical architecture. We can provide an exact cost after discussing the requirements.

Can I order both a website and a mobile app at the same time?

Yes, and it's actually convenient: the logic will be unified, so nothing will have to be patched together later. We develop both websites and apps - designing everything as a whole to ensure seamless functionality.

What happens after the launch?

We don’t disappear :) We provide ongoing support, update for new iOS and Android versions, ensure stability, and continue developing the project. For us, the launch is not the finish line but a growth point.

Will it be possible to add new features after the release?

Yes, and without hassle. We design the architecture from the start to allow easy scaling. Need a chat? Online payments? Dark mode? Everything can be added as the project grows.
