Case Study: IS app achieves secure, frictionless international phone verification for trusted location sharing with Twilio

IS goes Places with Phone Verification from Twilio’s Authy Service

InSite Applications built IS, a cross-platform, real‑time location‑sharing app designed to help friends and family keep up with one another while protecting user privacy. The team’s main challenge was implementing a simple, secure phone verification system that would scale internationally—previous providers required multi‑step flows and separate numbers per market, which added complexity and hurt the user experience.

IS integrated Twilio’s one‑click phone verification, using customizable messages and automatic country number handling. The API was straightforward to implement (under two days), reduced engineering overhead, accelerated the product roadmap, and delivered reliable international verification—helping IS launch faster, maintain user trust, and focus on refining its core location features.
