Questions & Answers

As answered by people managing OohSleep and Cert Decoder.

What's the story behind your product?

OohSleep's answer

OohSleep was born from a simple frustration — most sleep tracking apps are either too expensive, require invasive permissions, or lock you into a specific platform. We built OohSleep as a Progressive Web App to make quality sleep tracking accessible to everyone, on any device, for free. No app store gatekeepers, no cloud data collection — just better sleep.

Cert Decoder's answer:

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Which are the primary technologies used for building your product?

OohSleep's answer

HTML5, CSS3, JavaScript (Vanilla) Web Audio API for sound mixing and playback MediaRecorder API for sleep audio capture AI/ML for snoring detection and sleep analysis Progressive Web App (PWA) with Service Worker for offline support LocalStorage/IndexedDB for privacy-first local data storage

Cert Decoder's answer:

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

How would you describe the primary audience of your product?

OohSleep's answer

People who want to understand and improve their sleep without committing to expensive apps or subscriptions. This includes light snorers curious about their nighttime sounds, health-conscious individuals tracking sleep patterns, and anyone who uses white noise or breathing exercises to fall asleep. Our users value privacy and simplicity.

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Why should a person choose your product over its competitors?

OohSleep's answer

Unlike Sleep Cycle or Pillow, OohSleep requires no installation from an app store — just open the website and start tracking. It's free with no account required, keeps all your data private on-device (no cloud uploads), and works on any platform (iOS, Android, Windows, Mac) through the browser. Premium is just $14.99/year — far cheaper than most competitors' subscriptions.

Cert Decoder's answer:

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Who are some of the biggest customers of your product?

OohSleep's answer

OohSleep is a consumer product designed for individual users. As a newly launched app, we're growing our user base through Product Hunt, social media, and organic search. We serve individual users worldwide who want a free, private, and simple way to track and improve their sleep.

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

OohSleep's answer

OohSleep is a fully browser-based Progressive Web App — no app store download needed. It combines AI-powered snoring detection, 8 ambient sleep sounds, and 5 guided breathing exercises in one free tool. All data stays 100% local on your device for complete privacy, and it works fully offline after the first visit.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
