I need a clean, reliable mobile app that allows supporters to give to my NGO quickly and with confidence. The sole focus is donation collection, so every screen should guide users toward contributing and make the process feel seamless. I want donors to be able to choose between paying by credit or debit card and sending a direct bank transfer. Inside the donation flow they should find: • a toggle for one-time or recurring gifts • a personal donation history they can review at any time • an automated receipt emailed (and preferably downloadable) immediately after each transaction Security and transparency are critical. Please integrate a well-known payment gateway that is PCI-DSS compliant, secure the backend with modern best practices, and give me an admin view where I can monitor totals, filter by date, and export records for accounting. Clear error handling, easy localisation of currency/amount fields, and a branded, easy-to-navigate UI will round out the experience. Deliverables are a fully tested iOS/Android build, source code, simple deployment instructions, and a brief hand-off call so I can manage updates going forward.
