From an idea to a finished Android app.

Who it suits

Utility and productivity apps, file and system tools, scanners, calculators, timers, calendars, trackers, converters and media tools.

Supported capabilities

Local databases and storage, files, camera, microphone, GPS, NFC, Bluetooth, notifications, backup/export/import, system APIs, background services, Accessibility, VPN, media processing, charts and analytics — within the agreed scope.

Scope reviewed before payment

We do not take games, health/medical apps, government apps, banking/fintech platforms, server-based chats, social networks, marketplaces, ride-hailing, large SaaS or products built around a custom backend/server. If an idea falls outside our scope, we decline the project before payment.

Scope and UX/UI

We agree the idea, features, screens and integrations. We implement 1–3 actual key screens to establish the visual direction, with up to 2 revision rounds. Once approved, the direction is fixed.

A separate Figma mockup is not created by default. You may provide references, colors and brand assets; otherwise, Krepel Studio determines the UX/UI.

Android development and testing

Full implementation of agreed features, internal testing and release checks. We configure permissions and Android components, the agreed package, versionCode/versionName and current compileSdk/targetSdk at handoff.

Localization and identity

30 app localizations, a launcher icon and visual identity. These belong to the Android product itself, independently of the website’s 15 languages.

Monetization when needed

Google Play Billing and agreed Product IDs; AdMob with Google test IDs and prepared slots for the client’s production IDs. Third-party production accounts and credentials belong to the client.

Permitted integrations

Controlled external APIs and cloud features are possible if they do not turn the product into a backend-dependent platform. Google Drive backup requires the client’s own Google Cloud Project and API/OAuth configuration following our instructions.

Firebase requires separate approval and is not part of the standard package. Ongoing server administration by the studio is excluded.

Privacy and production builds

A ready Privacy Policy, signed production AAB/APK, source project and technical documentation. Play Console work and Google Play publication are arranged separately.

Project and release builds

The complete Source Project in ZIP/RAR, production AAB and APK. All 30 app localizations are already integrated into the source.

Signing and access

A dedicated keystore / upload key is handed to the client. The alias, password and other signing secrets are sent in a separate secure message, outside the main archive.

Assets and technical documentation

Launcher icon, unique assets, ready Privacy Policy and README / Technical Info: package, versions, SDK, Product IDs, AdMob status, permissions and agreed integrations.

Your product under your control

The specific app and its source code transfer to the client for publication, monetization, modification and further development. Krepel Studio retains rights to its reusable components and technical approaches.

A confirmed start date

We first approve the final Project Scope and confirm the order. Starting requires receipt of 100% payment in USDT, all necessary materials and access.

Krepel Studio separately confirms the Official Project Start via Telegram or email with a specific date. The timeline begins on that date; submitting a request or making a transfer alone does not start it.

Waiting for the client

Time spent waiting for a response, materials, access or revision approval is excluded from the studio’s timeline. The clock resumes once everything needed is received; if the reserved work slot is lost, work resumes in the next available slot.

Final acceptance

The final version includes 1 round of minor revisions within the agreed scope. New features, screens, substantial logic changes or a radical change to approved UI are separate work.

14 days after handoff

We fix technical defects, incorrect behavior of agreed features and visual errors against the approved result at no additional cost. New requests, features, localizations and scope changes are outside the bug warranty. Further work uses Updates & Support.

Google Play publication

Marketing materials, Play Console, testing tracks, Data Safety, Content Rating, declarations, production submission and review are excluded. You can order Full Google Play Publication for an app we created.

External costs and accounts

Developer Account creation and verification, registration fees, paid APIs, hosting, cloud/Firebase plans, domains, subscriptions and other external costs are excluded.

After the warranty

Future updates/support and changes in platform requirements need a separate service. Technical readiness does not guarantee downloads, revenue, ratings or commercial success.
