The average person uses 11 apps daily and loses 25% of their time to context switching. That's $25K wasted for every $100K of salary, moving information around instead of doing real work.

As answered by people managing DevPrep.app and Sugarbug.
DevPrep.app's answer
DevPrep.app offers a genuine two-way voice conversation for interview practice. The AI asks questions out loud, evaluates your spoken response, gives feedback, and asks follow-up questions just like a real technical interviewer would. Most tools make you type. Real interviews make you talk. DevPrep.app also includes 500+ flashcards across 15 topics with progress tracking and review mode, all working in your browser with no app install needed.
Sugarbug's answer:
Most tools in this space are another dashboard to check. Sugarbug isn't a destination – it connects the tools you already use and builds a knowledge graph across all of them. It doesn't replace Linear or Notion or Slack. It makes them work together by linking every signal, every person, and every task into a single picture. And that picture compounds – the longer it runs, the less work you do to stay informed.
DevPrep.app's answer
Most interview prep tools train you to write answers, not speak them. DevPrep.app trains the skill that actually matters in interviews — communicating clearly under pressure. It works in your browser with no app install, supports both desktop and mobile voice interviews, and includes 500+ flashcards with progress tracking across 15 topics.
Sugarbug's answer:
Competitors tend to solve one piece of the problem – a better notification layer, a smarter calendar, an AI summariser. Sugarbug solves the structural problem underneath: your information is fragmented across tools that don't share context. Instead of adding another app, Sugarbug sits behind the ones you have and does the stitching for you. Meeting briefs, status updates, people context – all built from real data across every source, not from a single silo.
DevPrep.app's answer
Software developers and DevOps engineers who are preparing for technical interviews.
Sugarbug's answer:
Product managers, design leads, and founders who run on more tools than they can keep in their head. People who spend a quarter of their week moving information between apps instead of doing the work the information is about. If your day involves checking Linear, then Slack, then Figma, then Notion, then your calendar just to prepare for one meeting – Sugarbug is built for you.
DevPrep.app's answer
Built by a developer who noticed that knowing the answers and being able to say them confidently out loud are completely different skills. Most prep tools only train one of them. DevPrep.app was built to train both.
Sugarbug's answer:
Two people – a Head of Design and a Head of Product – were drowning in the same problem: too many tools, too much context switching, too little time for the actual work. Every existing solution was either another app to check or an AI wrapper around a single tool. So they built Sugarbug as a shared brain – one system that watches everything, understands the connections, and does the legwork so they can focus on what matters.
DevPrep.app's answer
ASP.NET Core 7, React, TypeScript, Azure OpenAI (GPT-4o), Azure Cognitive Services Speech SDK, Web Speech API, Azure Container Apps, Azure Static Web Apps, Stripe, SQL Server
Sugarbug's answer:
Native app across macOS, Windows, Linux, iOS, Android, and browser. The AI layer is fully provider-agnostic – bring your own LLM, no vendor lock-in. All integrations connect via official APIs over secure private networking. No Electron.
