I build web tools and small SaaS products, mostly on weekends, from New Delhi. I run ScreenTail and decide what every tool on it does.
How I got here
Computers have been the thing since I was about eight — not a hobby so much as an obsession. While friends were working out how to use software, I was inside the case figuring out what each part did. That turned into a Computer Science degree, and a day job as a manager at a tech company. Twenty-five years on, it hasn't worn off.
ScreenTail exists because bad pixels bother me more than is reasonable. One dead dot on a screen I use every day is something I'll notice every single day. Once I started building tools to find them properly, it turned into the 105 tools on this site.
What I don't claim
I'm a tinkerer with an unreasonable tolerance for detail. If something's broken I'll open it up rather than replace it. That isn't expertise, and I won't dress it up as any. I am not:
- A display engineer
- Someone who has worked for a panel manufacturer
- A color scientist
- Someone who has professionally calibrated a display
That is stated here plainly, because anyone deciding whether to trust a dead-pixel result deserves to know.
How ScreenTail is made
I decide what each tool does and what goes on the site, and nothing is published until it has passed the automated checks set out on How We Test. I have also checked the site myself on a phone, a laptop and a 4K monitor. That is why every tool page says what it can and cannot show you: the method is written down where you can check it.
In the guides, every figure and manufacturer policy is checked against a named source before it is published.

If something's broken
Anything to do with ScreenTail reaches me directly at contact@screentail.com (the contact page says what helps most). That includes a tool that misbehaves on your hardware: the one thing one person cannot test alone.
