UI/UX for small screens
Thumb reach, readable type, and flows that survive interruptions.

Mobile App Development for Android and iOS
A useful mobile app is a product: onboarding, permissions, offline behaviour, notifications, account recovery and store listings all matter as much as the first screen. ZEH Technologies designs and develops mobile applications for Android and iOS with the backend and admin tools that keep the app alive after launch.
We cover UI/UX, backend APIs, authentication, notifications, subscriptions, analytics, payments, cloud integration, application security, deployment, Google Play and Apple App Store submission support. We do not treat a wrapper around a website as a finished product unless that is the agreed scope.
AuroGuard VPN is a live Android product on Google Play. That experience informs how we handle store listings, privacy URLs, support pages and release hygiene—without inventing security guarantees the product does not document.
Backend APIs
REST APIs, auth tokens and versioned endpoints.
Authentication
Sign-in, session handling and account recovery patterns.
Notifications
Transactional alerts with sensible frequency and deep links.
Subscriptions & payments
Store billing or payment APIs where the product requires them.
Analytics
Events that explain funnel drop-off without stalking users.
Cloud integration
File, config and data sync through documented APIs.
Security & deployment
Transport security, secret handling, Play and App Store delivery.
Android, iOS or both
Native Android and native iOS still win when you need deep platform behaviour. Cross-platform can win when the product is the same on both stores and the team must move as one. We help you choose on the native vs cross-platform criteria: device APIs, team skills, timeline and how often the UI must feel platform-native.
Business apps sometimes ship Android-first because of audience mix or an existing Play listing. That is a valid sequence, not a permanent limitation.
What sits behind the app
Most commercial apps are clients of a backend. We build that backend with authentication, roles, webhooks and admin screens so operations are not trapped in a developer laptop. See API & backend development.
If the app needs AI features—summaries, assistants, document intake—those are scoped as AI development, not as a mysterious toggle.
Stores, privacy and support
Google Play and App Store review is part of delivery. Privacy policy, terms, data deletion and support URLs must already work. We keep those pages on stable public paths, as we do for AuroGuard.
We do not claim an app is unhackable or 100% secure. We implement reasonable controls and describe them accurately.

FAQ
Questions companies usually ask.
Do you publish to Google Play and the App Store?
We prepare builds, listings, privacy URLs and submission packages. Store approval is still decided by Google and Apple.
Can you build the API as well?
Yes. Most app projects include a backend.
Do you only build consumer apps?
No. Many projects are staff, partner or customer-account apps.
