Nightcap Sleep Timer
A sleep timer for your computer that slowly dims the screen and lowers the volume before putting it to sleep.
What is Nightcap Sleep Timer?
Nightcap is a sleep timer for your computer, modeled on the sleep timer found on many TVs. You pick a length, such as 15, 30, 45, 60 or 90 minutes, or set a custom length. When the timer runs out, Nightcap can put your computer to sleep, hibernate it or shut it down, based on your choice.
Before that happens, Nightcap gradually dims the screen to a level you choose and lowers the volume on its own schedule, so the show you fell asleep to trails off instead of cutting out. Displays without brightness control get a dimming overlay instead. When you cancel the timer or wake your computer, brightness and volume return to where they were.
Nightcap is aimed at anyone who likes to fall asleep to a video, podcast or music on their computer and wants the machine to wind down by itself. It runs from the menu bar on Mac, or the system tray on Windows and Linux, so you can start, pause, extend or cancel a timer without opening a window. It works offline and needs no account.
Nightcap is free and open source software for Mac, Windows and Linux, licensed under MIT or Apache 2.0.

I'm having a fake conversation with a real person. So I'm having a conversation with this guy who was leaving me a one-star review saying I got this free for nine years and now I have to pay.
War-Game the Uncomfortable Conversation Before Making the Aggressive Decision
Before making price changes or removing free access, Alex Prasad role-plays the entire customer conversation in his head — not just the angry review, but the full back-and-forth. If the company's side of that imagined conversation still feels reasonable, the decision is defensible. This mental habit of treating digital users like real people standing in front of you is his primary substitute for large-scale user research.
There's two different types of apps — there's innovating new ideas and there's modifying versions of existing ideas. If you're creating a modified version of an existing app then congrats, your app is already validated by other people. Now all you have to do is make some modifications and make it so the app feels like it's your own.
Split Every Idea Into Modified Version Of A Winner Or A Brand-New Demand Test
Connor splits ideas into 'modified versions' (pre-validated by an existing winner) and 'brand new' (validated by reading TikTok and Instagram comments asking how to solve the problem). For modified apps he skips validation entirely because someone else already proved demand — the only work left is making it feel like yours.
There's a play for whatever you're stuck on.
