Tablet App Developer – Offline Will Writing Data Capture App (with optional CMS)

We’re looking for an experienced mobile app developer (Android or iOS) to build an offline-first tablet app for our Will Writers who carry out home visits. During each visit, the app must allow Will Writers to: - Complete a structured questionnaire (we’ll provide the current paper version). - Record the full meeting audio. - Capture and store photos of clients’ ID documents. - Work entirely offline, saving all data locally until internet is available. - Once online, automatically email all collected data, photos, and audio to a designated secure email address. We need two options costed and explained in your proposal: Option 1 – Updateable version (with web CMS) --------------------------------------------------------------- A centrally managed version that connects to a secure web-based CMS. The CMS allows authorised staff to update questions and logic without needing a developer. When tablets connect to the internet, they automatically receive updates. Key points: - Full offline functionality. - Automatic form updates from CMS. - Secure local data storage (AES-256 encryption). - PIN-protected access. - Auto-delete after successful submission. - CMS with admin login and version tracking. Option 2 – Flat standalone version (no CMS) --------------------------------------------------------------- A simpler version where the questionnaire is built into the app itself. Any updates would require a developer to make and deploy a new version. Key points: - Same offline workflow (form + audio + photos). -Secure email submission once online. -PIN-protected, encrypted local storage. -Manual updates only. Developer requirements --------------------------------------------------------------- - Experience with offline-first mobile apps. - Expertise in audio and image capture APIs. - Knowledge of secure data storage, encryption, and GDPR compliance. For Option 1: CMS/web admin experience (React, Node.js, or Laravel). --------------------------------------------------------------- - Strong UI/UX design for non-technical field users. Tablet recommendation --------------------------------------------------------------- Please include a hardware recommendation (specific model and specs). Consider: high-quality microphone, 12MP+ camera, 128GB+ storage, long battery life, UK availability, and reliability for offline data collection. Deliverables --------------------------------------------------------------- - Working offline tablet app. - Email submission of data, photos, and audio. - Secure local storage and deletion after sending. - Technical documentation. (Option 1 only) Web CMS and admin dashboard. --------------------------------------------------------------- Include in your proposal - Tech stack recommendation and reasoning. - Timeline for both options. - Tablet recommendation. - Example of similar offline or data-capture app. - Approach to encryption and secure emailing. --------------------------------------------------------------- We are a UK-based Will Writing and Estate Planning firm working nationwide. Our Will Writers visit clients at home, often without internet access. This project will modernise how we collect and transmit data securely and efficiently.
