How Altivra Builds iOS Apps: Native Swift, Privacy-First AI
Altivra is an independent iOS app studio founded by Dawid Jelski in the UK. We ship four live apps — SignDesk, FitMind, NeuroSleep, and PlantMind — each solving a different everyday problem with native Swift and thoughtful AI integration.
This post explains how we approach iOS app development: not as a generic agency playbook, but as a small studio optimising for quality, privacy, and long-term maintainability.
Why native iOS — not cross-platform
We build 100% native iOS apps with Swift and SwiftUI. Cross-platform frameworks can speed initial prototypes, but for apps deeply integrated with HealthKit, Vision, PDFKit, and on-device ML, native APIs win on performance, polish, and access to Apple's latest platform features.
Our users expect apps that feel like they belong on iPhone — fluid animations, proper Dynamic Type support, and system integrations that cross-platform wrappers often lag behind.
One studio, four product lines
Each Altivra app is a dedicated product with its own design language, feature set, and App Store listing — not a white-label template with swapped colours.
| App | Focus | Core tech | |-----|-------|-----------| | SignDesk | PDF sign, scan, organise | PDFKit, Vision, optional AI | | FitMind | Fitness & nutrition AI | HealthKit, workout generation | | NeuroSleep | Sleep & recovery | HealthKit, on-device coaching | | PlantMind | Plant ID & care | Vision, care schedules |
Shared studio standards (privacy policies, subscription disclosures, support workflows) keep compliance consistent without forcing identical UX.
Our development workflow
1. Problem first, AI second
We start with a real user problem — signing a lease on iPhone, tracking sleep recovery, identifying a houseplant — then ask whether AI genuinely improves the solution. AI is a tool, not a marketing sticker.
2. Design in SwiftUI
SwiftUI lets us iterate quickly on dark-theme interfaces, glass-style components, and responsive layouts that match the premium feel of our marketing site. Product pages on altivra.co.uk reflect the same visual language as the apps.
3. Integrate Apple frameworks deliberately
- HealthKit for FitMind and NeuroSleep
- Vision for document scanning and plant identification
- PDFKit for SignDesk's core document workflow
- Core ML / on-device models where privacy and offline use matter
See on-device AI explained for why we prefer local processing.
4. Ship App Store compliance early
Apple's requirements — privacy labels, subscription disclosures (Guideline 3.1.2), Standard EULA references, support URLs — are not post-launch chores. We publish legal pages on altivra.co.uk/legal before submission and keep App Store Connect metadata in sync.
5. Iterate from real usage
Indie development means direct feedback loops. Support emails, App Store reviews, and personal dogfooding drive the roadmap — not committee meetings.
AI integration without the hype
When we add AI to an Altivra app:
- Explain limitations — AI contract summaries are not legal advice; plant ID may misidentify rare species; sleep scores are wellness tools, not medical diagnoses
- Default to on-device where accuracy allows
- Make cloud optional with clear opt-in (SignDesk's optional OpenAI key is an example)
- Document everything in per-app privacy policies
Subscriptions and sustainable indie development
Three of our apps use App Store subscriptions; FitMind offers premium tiers including lifetime options. Sustainable indie studios need revenue models that align with ongoing development — not ads that compromise privacy or dark patterns that erode trust.
We follow Apple's subscription disclosure requirements on every pricing page and in-app paywall.
What we are building next
The Altivra changelog tracks product updates across all apps. We prioritise depth over breadth — making SignDesk the best local PDF workspace, NeuroSleep the clearest sleep recovery tool, rather than launching ten shallow apps.
Resources for aspiring iOS developers
If you are learning iOS development or considering indie app studios:
- Apple's SwiftUI tutorials remain the best starting point
- HealthKit requires careful permission UX — read Apple's Human Interface Guidelines for health apps
- App Store review feedback is blunt but useful; treat rejections as free QA
