Voicealerts

Inspiration

Modern reminders are still built for tapping and typing, even though our lives are increasingly hands-busy and multi-device. We were inspired by the idea that reminders should work the way people think and speak: fast, natural, and everywhere, not buried behind friction.

What it does

VoiceAlerts is a voice-first reminder app that lets users set, manage, and snooze reminders using natural speech. When a reminder triggers, users can respond hands-free, even snoozing it by voice - with changes syncing instantly across all devices.

How we built it

We built VoiceAlerts as a cross-device system with a mobile-first experience. Voice commands are converted to text and interpreted using OpenAI , enabling natural language understanding for reminders like timing, intent, and snooze duration.

Structured reminders are synced through a central backend and delivered via real-time alerts. RevenueCat manages subscriptions and entitlements, allowing premium features to unlock instantly everywhere the user is signed in.

Challenges we ran into

The biggest challenge was designing voice interactions that feel reliable in time-sensitive moments. Parsing natural language durations, handling edge cases, and providing clear feedback without overwhelming the user required careful UX and system design.

Accomplishments that we're proud of

We built a fully demo-able, end-to-end experience where voice, reminders, notifications, and monetization work seamlessly together. The ability to snooze a live reminder by voice - is a moment that feels genuinely magical and intuitive.

What we learned

Voice works best when it removes friction at exactly the right moment. We learned that users don’t want to “talk to an app” - they want to get something done quickly and trust the system to understand them without correction.

What's next for Voicealerts

Next, we plan to expand smarter voice understanding, richer collaboration through shared reminders, and deeper integrations with wearables and system-level assistants. The goal is to make Voicealerts feel less like an app and more like a natural extension of memory.
