In-House & Public Mobile Apps

Proprietary & Consumer-Facing Apps. We design, build and publish high-performance iOS and Android applications that connect users directly with smart recycling infrastructure. Our flagship app since 2018, Recycle-Cornerstone (available on Apple App Store and Google Play), enables everyday citizens to discover nearby smart bins, track real-time recycle transaction, and manage earned points on the go.

Customizable Apps

Tailored Solutions for ESG & Funded Projects. Cornerstone develops customized and/or white-label applications tailored for specific corporate initiatives, academic grants, and government-funded schemes. From the latest Environment and Conservation Fund (ECF) community program in 2026, Cornerstone as the RVM operator, build secure, branded digital apps for users to redeem rewards with points after recycling from the Gift Center in the Eco-Buddy app.

Digital Reward Program & Gift Center

Seamless Points Redemption & Incentive Management. Turn eco-actions into tangible rewards. Our integrated Gift Center module allows organizations to set up automated catalog redemptions—enabling users to exchange earned recycling points for e-vouchers, physical gifts, discount privileges, or partner coupons. We handle the entire lifecycle from point calculation to digital voucher fulfillment.
