# NEDIO > A sprint timer and curated instrumental focus audio product for developers, in the browser or inside VS Code and Cursor. One goal per sprint, no lyrics, no ads, and a session log of what actually landed. NEDIO is not a generic Pomodoro app or a generic music player. It pairs a coding-sprint timer with one instrumental audio stream and a close-out step that records what you meant to do against what you reported. NEDIO plays curated instrumental audio, with no lyrics and no ads, as one stream per sprint with no track or station picker. The audio is generated with a third-party generative music tool in advance and assembled into continuous mixes by NEDIO. It is not recorded by performers or licensed from a music library. NEDIO does not read your source code, file names, or repository names, in the browser or in the VS Code and Cursor extensions. NEDIO does not check whether your goal was reached or whether your code works. It records what you tell it. ## Product - [NEDIO](https://nedio.xyz/) - [NEDIO for VS Code](https://nedio.xyz/vscode) - [NEDIO for Cursor](https://nedio.xyz/cursor) - [AI Review](https://nedio.xyz/ai-review) - [Focus music for developers](https://nedio.xyz/focus-music-for-developers) - [Focus time tracker for developers](https://nedio.xyz/focus-time-tracker) - [Coding sprint timer with preset intervals](https://nedio.xyz/coding-sprint-timer) - [Pomodoro timer for developers](https://nedio.xyz/pomodoro-for-developers) ## Guides - [Pomodoro alternatives for coding: 25/5, 50/10, and timeboxing](https://nedio.xyz/guides/coding-sprints/best-sprint-length-for-coding) - [Stop coding and resume tomorrow without rebuilding context](https://nedio.xyz/guides/coding-sprints/stop-coding-and-resume-tomorrow) - [Review AI-generated code without losing the thread](https://nedio.xyz/guides/ai-coding/review-ai-code-without-losing-context) - [Escape an AI debugging loop](https://nedio.xyz/guides/ai-coding/escape-ai-debugging-loops) - [How to focus while coding — and why developers lose it](https://nedio.xyz/guides/focus/why-developers-lose-focus-and-how-to-get-it-back) - [Deep work for developers](https://nedio.xyz/guides/focus/deep-work-for-developers) - [How to focus on code](https://nedio.xyz/guides/focus/how-to-focus-on-code) - [Best focus music for ADHD developers](https://nedio.xyz/guides/focus/best-focus-music-for-adhd-developers) ## Research — primary sources - [Lyrics vs instrumental music for coding](https://nedio.xyz/research/lyrics-vs-instrumental-for-coding) - [Best music for coding: lyrics, lo-fi, white noise, volume, and task type](https://nedio.xyz/research/best-music-for-coding) - [Binaural beats for coding: useful or hype?](https://nedio.xyz/research/binaural-beats-for-coding-useful-or-hype) - [Context switching cost for developers](https://nedio.xyz/research/context-switching-cost-for-developers) - [White noise vs music for coding](https://nedio.xyz/research/white-noise-vs-music-for-coding) - [What research says about focus habits, breaks, and work interval design](https://nedio.xyz/research/focus-habits-breaks-and-work-interval-design) - [The refactor you did instead: AI made procrastination look like work](https://nedio.xyz/research/ai-procrastination-in-software-development) ## Comparisons - [Brain.fm alternatives](https://nedio.xyz/compare/brain-fm-alternatives) - [Endel alternatives](https://nedio.xyz/compare/endel-alternatives) - [Brain.fm vs NEDIO](https://nedio.xyz/compare/brain-fm-vs-nedio) - [Best focus apps for developers](https://nedio.xyz/compare/best-focus-apps-for-developers) - [Best coding music apps for developers](https://nedio.xyz/compare/best-coding-music-apps-for-developers) - [Best Pomodoro apps for developers](https://nedio.xyz/compare/best-pomodoro-apps-for-developers) - [Calm vs NEDIO](https://nedio.xyz/compare/calm-vs-nedio) - [Endel vs NEDIO](https://nedio.xyz/compare/endel-vs-nedio) - [Spotify vs NEDIO](https://nedio.xyz/compare/spotify-vs-nedio) - [YouTube lo-fi vs NEDIO](https://nedio.xyz/compare/youtube-lofi-vs-nedio) - [Headspace vs NEDIO](https://nedio.xyz/compare/headspace-vs-nedio)
