Choose the right format.
One-Time Update covers one agreed release cycle. Both App Care packages share the same scope and differ in duration.
An individual update
For a specific agreed set of changes to one existing app. This is a release cycle, not a subscription or a calendar month.
App Care
For ongoing technical readiness, monthly maintenance and development of a fixed list of up to two apps throughout the paid period.
One-Time Update: one app, one cycle.
The fixed price applies once the studio confirms that the request fits this format.
Possible changes
Bug fixes, UI/UX and a complete visual refresh, screen redesign, texts and localizations, Android/Google Play adaptation, existing feature changes, major new features, refactoring and optimization — when agreed as one update.
The same product
The app must retain its main purpose. Turning it into a genuinely different product is a new Android App Development order. Requests made after approval are not automatically added to the agreed scope.
Handoff and pricing per app
The client receives updated source, AAB and APK. Each additional app is charged separately at the same fixed price. Publishing the update in Google Play is not automatically included and requires separate agreement.
App Care: complete care for up to two apps.
The specific app list is fixed at the start; the term begins on the separately confirmed App Care Start Date.
Technical readiness
Android versions, compileSdk/targetSdk, dependencies and compatibility, R8/ProGuard/optimization, release-build fixes, Google Play requirements, Data Safety, permissions/declarations and technical Billing/AdMob changes for the supported apps.
Development on request
Unlimited requests for bug fixes, UI/UX, full redesigns, screens, texts, new localizations, major features, deep refactoring, architecture changes and performance optimization.
Deep modernization
The supported app’s concept may change substantially while remaining the same active app/project. App Care does not create additional separate products; a third new app is ordered separately.
Maintenance every month for every app.
At least 1 planned maintenance cycle each month, regardless of the client’s own requests and in addition to them.
What we check
Technical condition, current Android/Google Play requirements, SDK, dependencies and release readiness. We make necessary changes and prepare and publish a maintenance release when needed.
Minimum cycles over the term
For 1 app: 6 months includes at least 6 cycles; 12 months includes at least 12. For 2 apps: at least 12 and 24 cycles in total respectively. A cycle does not require a separate publication if no release is needed.
Client blockers
Missing access or materials may pause a task but do not automatically extend the paid App Care term. Unused time does not accumulate or carry over; a blocked cycle is performed once the blocker is removed, provided App Care remains active.
Unlimited requests. Sequential work.
Priorities may change during the active term; the studio’s technical scope still applies.
Sequential work by priority
Unlimited requests do not mean unlimited parallel work. We complete them sequentially in our work queue, with priorities agreed with the client.
The queue does not automatically extend the paid period. Tasks already in active work before the end date are completed. New or not-yet-started requests after that date require a new agreed service.
An actual bug reported during the active warranty or support period is fixed under that warranty even if the fix is completed after the period’s final day.
Google Play publication in support.
App Care includes support/maintenance update publication; One-Time Update requires separate agreement.
Included in App Care
When needed, we prepare the release, update declarations, Data Safety and Play Console settings, upload the AAB, submit the release and support review during the active period.
Access and updated files
Releases require the client’s current signing information and necessary access. After an update, we hand over updated source, AAB and APK. Third-party accounts remain the client’s property.
Support boundaries.
A broad range of possible changes remains subject to the agreed technical scope.
Additional new products
One-Time Update retains the product’s main purpose. App Care allows deep modernization of supported apps, but does not create additional separate apps beyond the fixed list.
Technical and external limits
Games, health/medical apps, government apps, large server/backend platforms and other excluded categories are not accepted. Google Drive backup requires the client’s own Google Cloud Project and credentials; Firebase requires separate agreement. Paid external services are not automatically included.
After the paid period
Platform changes and new requests after the warranty or support period require a separate service. Paying for support does not guarantee revenue, downloads or other business outcomes.
We build products. We know the whole journey.
We don't just develop Android apps for clients. We create, publish and support our own products at Google Play.
