Retain UsersAcquiring users is the easy part. Keeping them is where most apps fail. Svype builds iOS and Android applications with retention as a design requirement from the first wireframe — not a feature added after launch when churn data makes the problem visible.

Three Failures Worth Avoiding
Most app failures are not technical failures. They are product decisions made before a line of code is written.
Onboarding optimised for speed produces users who never form a habit. Retention starts at onboarding. Svype designs the first session around the outcome the user needs to experience, not the shortest path to account creation.
App Store and Google Play reject apps a structured QA process would have caught. Rejection delays launch, requires fixes, and resubmission. QA covers functionality, edge cases, device compatibility, and guideline compliance before any build is submitted.
OS updates and device changes produce issues that did not exist at launch. An app with no post-launch support deteriorates with no one responsible for fixing it. Post-launch support at Svype is included as standard, not an optional extra.
Seven Stages From Brief To App Store
The product purpose, the target user, the core action the user needs to complete in each session, and the retention metric the product will be measured against are defined before any design work begins. The retention goal shapes every UX decision that follows.
Every user journey through the app is mapped before wireframes are drawn. The critical paths, the edge cases, and the failure states are all identified at this stage. Issues found in the flow map cost nothing to fix. Issues found in development cost significantly more.
Low-fidelity wireframes are produced for all key screens and reviewed against the user flow map. The wireframe review is the cheapest point at which to identify structural UX problems. Client feedback at this stage produces the approved structure that the UI design is applied to.
Visual design is applied to the approved wireframe structure. Platform-specific UI conventions are followed for iOS and Android separately. Interactive prototypes are produced for the primary user flows so the client can review the experience before development begins.
Development is structured in sprints with working builds delivered at each milestone for client review. The client sees the product working at each stage, not only at the end of development. Issues identified during milestone reviews are addressed in the next sprint.
Full QA is completed before any build is submitted to the App Store or Google Play. Store listing assets, compliance documentation, and metadata are prepared alongside the technical submission. Both are submitted together.
Post-launch monitoring covers crash reports, performance metrics, and early user behaviour data. The first two weeks after launch are the most important period for identifying issues that QA did not surface. Issues are addressed on the same priority timeline as pre-launch fixes.
What Svype Does Different
The retention goal is defined in the brief and used as the primary filter for every UX decision. What the user needs in their first session and what brings them back are answered in the wireframe stage, not a post-launch roadmap.
The team that designs the UX builds the product and tests it. No handoffs between design, development, and QA. When one team holds all three stages, design intent survives through development and output is tested by people who know what it should do.
Post-launch support is included from the start, not negotiated after completion. OS updates and real-world load produce issues that appear after launch. Having the same development team available to fix them is faster and cheaper for both sides.
Before The Project Starts
Here are the answers to some questions we get asked often
A typical engagement runs twelve to twenty weeks from brief to App Store and Google Play submission — UX and UI design in the first three to four weeks, development and QA through the middle phase, and store submission in the final two weeks. Complex apps with hardware integration, offline functionality, or third-party API dependencies take longer. Timelines are confirmed in the proposal after the brief, not estimated generically.
Native development produces better performance and a more platform-appropriate user experience for apps that use device hardware intensively: camera, GPS, sensors, or offline functionality. Cross-platform frameworks produce faster development timelines and lower costs for apps where the primary value is content delivery or transactional functionality that does not require deep hardware integration. The brief defines which applies, and the technology recommendation follows from it.
Apple and Google review every build before it goes live. The review covers functionality, privacy policy compliance, metadata accuracy, and adherence to platform guidelines. Rejected apps require fixes and resubmission, which delays launch. Svype runs structured QA against store guidelines before any build is submitted, manages metadata and listing creative, and handles rejection response and resubmission as part of the engagement.
Yes. On project completion, the client receives full ownership of the source code, design assets, and store account credentials. There is no ongoing licensing fee and no dependency on Svype to maintain or update the app after handover. Post-launch support is included as standard during the support period defined in the proposal — it is not a condition of retaining access to the codebase.
Post-launch support covers bug fixes, OS compatibility updates, and performance monitoring after the app goes live. OS updates and new device releases produce issues that did not exist at launch. Support is included as standard — not sold as an optional retainer after the project closes. The scope and duration are defined in the proposal so there is no ambiguity about what happens after submission day.
Our Clients
Every client that has trusted Svype for their top-notch work
Every engagement starts with a 30-minute discovery call. No pitch decks and no generic proposals are sent before a real conversation happens. Svype identifies where the commercial gap is and proposes a specific plan to close it, including the target it will be held against.
