How we work

Three moves.
No detours.

0101

Research

We dig into the problem space before touching a single screen. Utility apps live or die by how precisely they solve one thing — so we aim to understand that one thing completely before we scope.

0202

Design

Interfaces are designed to be invisible. We prototype in Figma, stress-test edge cases, and cut anything that doesn't earn its place — because every tap costs the user attention.

0303

Ship

We build in Swift and SwiftUI, integrate analytics and monetisation from day one, and aim to get to TestFlight before the brief is cold. Iteration is the plan.

WORK
Stack

Tools we trust.

We aim to stay close to the platform — native Swift over cross-platform, purpose-built analytics over bloated SDKs. The stack is chosen to stay out of the way.

STACK
What we don't do

Hard limits.
No exceptions.

Principle 01

No white-label.

We build products we can stand behind publicly. Anonymous work for anonymous clients isn't something we aim to take on.

Principle 02

No gambling or ad-heavy products.

Dark patterns and engagement loops designed to extract attention aren't in our scope — regardless of budget.

Principle 03

No spec work.

We don't design on speculation. Every engagement starts with a paid discovery phase — that's how we protect both sides.

Principle 04

No support without a retainer.

Post-launch maintenance is a real commitment. We aim to structure it properly or not at all — ad-hoc firefighting helps no one.

FAQ

Common questions.

We focus on single-purpose mobile tools — productivity aids, habit trackers, personal finance helpers, health logging, and similar focused utilities. We aim to work on apps where the value proposition fits in one sentence. If it needs a paragraph to explain, it probably needs a different studio.

A focused utility app typically moves from signed brief to TestFlight in eight to fourteen weeks. That range depends on scope, not on how busy we are. We aim to keep the scope honest from day one so the timeline stays honest too.

Send an email to litvaksdaniils@sdlest.com with a short description of what you want to build and why. We'll reply with a few questions. If there's a fit, we'll propose a paid discovery phase — a short, fixed-scope engagement to validate the idea and produce a concrete brief before any build commitment.

We offer structured retainer arrangements for studios that want ongoing iteration, bug triage, and App Store maintenance. We aim to scope these clearly upfront. Ad-hoc support requests outside a retainer aren't something we take on — it's not a policy, it's a quality decision.
