Yeluvon — app support
Keeping mobile applications running after they launch — without surprises.
Background
Started in 2017 from a specific gap
Most development teams hand off a finished app and move on. The client is left with documentation, a codebase, and no clear answer for what to do when the iOS update breaks three screens or a critical payment API changes its authentication method.
Yeluvon was set up to fill that gap. The work is narrow by design — mobile app support, maintenance, and updates. Nothing else. Each client gets direct access to the same specialist throughout, not a rotating helpdesk.
The team works remotely and covers clients across Ukraine and neighbouring regions. Regional familiarity matters when local payment providers, government APIs, or platform-specific rules affect how an app functions.
Scope of work
What the service actually covers
Support here means responding when something breaks, not waiting for a client to report every issue. Regular checks catch dependency conflicts and SDK deprecations before they surface to users. When Apple or Google push a platform change, the app is updated to stay compliant.
Updates include both reactive fixes and planned iterations — new fields in a form, adjusted push notification logic, refreshed UI elements. The scope is agreed at the start and reviewed if the app grows significantly.
Confidentiality is a practical concern, not a marketing point. Client source code, user data, and internal business logic stay private. No case studies are published without explicit written permission.
Direct communication
Requests go to the person doing the work, not through a ticket queue managed by someone else. This keeps context intact and avoids the lag that builds up when multiple handoffs happen before anyone opens the code.
Regional context
Ukrainian banking integrations, local regulatory requirements, and regional app store behaviour have specific quirks. Working with a specialist who already knows them reduces the back-and-forth needed to explain context from scratch.
Defined agreements
Each engagement starts with a written scope. What is covered, what falls outside it, and how changes are handled — all agreed before work begins. No ambiguity about what a support request includes.
