Our Valuable Clients
## Success Stories of Our Fintech Mobile App Development
Partner with a trusted fintech app development company to build mobile apps that improve user retention, streamline financial operations, and drive sustainable growth across digital banking and payment ecosystems.
### [PayNowlink: Contactless Payment Solution](/project/paynowlink-app-for-stripe-checkout/)
**Space-O Technologies** developed PayNowlink, a contactless payment app that generates Stripe checkout links for quick transactions. Built during COVID-19, this solution eliminates manual invoices and EFTPOS machines, requiring only a Stripe account. The app supports 130+ currencies, adjustable settings, and test mode functionality.
Our client previously launched PayNow for Stripe with 50,000+ users, prompting the development of this enhanced version to promote social distancing and streamline business operations without physical payment infrastructure.
[See Project Details](https://www.spaceotechnologies.com/project/paynowlink-app-for-stripe-checkout/)
### [PayNow for Stripe: NFC Payment Innovation](/project/paynow-for-stripe-app/)
We created PayNow for Stripe, a minimalist point-of-sale app accepting credit card payments via NFC technology on smartphones. This Australian-based solution replaced costly EFTPOS machines ($360/year) with secure mobile payments, ranking 3rd among Australia’s top innovative apps.
Built with Swift 2.0, Card.io, and Stripe integration, our iOS developer completed the project in 1.5 months. The app serves delivery businesses and on-demand services requiring quick, secure payment collection.

### [CharityCalc: Gift Annuity Calculator](https://www.spaceotechnologies.com/project/gift-annuity-calculator-app-development/)
Space-O Technologies built CharityCalc, a mobile-first financial planning tool for charitable gift annuities using Flutter, PHP Laravel, and PostgreSQL. The app handles seven to eight distinct gift annuity models with single-life and joint-life scenarios, processing data from multiple government sources.
Users calculate returns on charitable investments, understand tax benefits, and generate professional PDF summaries instantly. CharityCalc fills a market gap by providing mobile-based calculations previously limited to websites.
