The stack we build and ship on
Our products
Not a portfolio of mockups. These are live listings under our own developer account, with the store metadata to prove it.
A gentle space for your soul
A mental wellness platform that bridges everyday emotional care and professional support. Soulene combines AI-driven insight, structured self-assessments and one-to-one mentorship so wellbeing becomes a continuous journey rather than a one-off fix.
Where logic meets magic
A one-tap directional puzzle game. Slide arrows to clear the board, unlock special Blue Magic and Golden Arrows, and avoid hidden bombs across timed levels of increasing difficulty.
What we do
From the first architecture decision to the store release and the versions that follow it.
End-to-end mobile products: architecture, interface, build, store submission and the release cadence that follows.
Practical AI inside real products — insight generation, structured assessment scoring and natural-language interaction.
Fast, accessible marketing sites and web applications built on a modern React toolchain.
APIs, data stores and deployment pipelines sized to the product rather than to a slide deck.
Handling sensitive data properly: encryption in transit, deletion workflows and store-policy compliance.
Interface design, motion and brand systems that survive contact with a real product roadmap.
Industries
Our own products live in wellness and gaming, which is where our deepest domain knowledge sits.
Consumer wellbeing products handling sensitive self-reported health data under store health policies.
Casual and puzzle titles with level design, progression systems and store launch.
Multi-tier subscription products with billing, entitlements and usage analytics.
Booking, mentorship and scheduling platforms that connect clients with practitioners.
Structured learning content, assessments and progress tracking.
Storefronts, catalogues and payment journeys built for mobile-first shoppers.
How we work
No black box. Each phase has named deliverables so you always know what you're getting and when.
We pin down what the product must do, who it serves and which constraints are real before writing code.
Interface design and system architecture happen together, so the experience and the data model agree.
Short iterations with working software at the end of each, reviewed against the criteria we agreed.
Testing, performance work, privacy review and the store-policy checks that block launches late.
Store submission, review handling and release. We have taken this path on both App Store and Google Play.
Monitoring, version updates and iteration once real users arrive — where most of a product's life is spent.
Technology
Modern where it earns its keep, conventional where predictability matters more than novelty.
Why S3 Cubes
Soulene and Arrow Land are ours — designed, built, submitted and maintained in-house. We carry the same release discipline into client work.
App Store and Play review, privacy labels, health-data policies and subscription rules are things we have already navigated.
Encryption in transit, user-initiated data deletion and anonymised AI processing are defaults, not upsells.
You talk to the people building your product. No account-manager relay, no rotating offshore bench.
Pick the shape that fits your team. We'll tell you honestly if a different one suits you better.
A defined build with a clear finish line
Agreed deliverables, milestone billing and a documented handover.
Ongoing product development
An embedded team working to your roadmap as an extension of your own.
Founders without an in-house team
We own architecture, delivery and operations for the long run.
