Now and then, the Prod Extension will show small tips.
These tips aim to improve your productivity and happiness through marginal gains.

The Startup Book Club

Hi everyone, thanks for using Prod.

As you know, Prod is free, doesn't show ads, sell your data, or anything annoying like that.

Instead, now and then, I ask you to check out one of my other projects:

The Startup Book Club is a collection of the books most recommended by startup founders and tech pioneers. It's also a book club. Every two weeks, starting in 2019, we'll read one of these books. Take a look:

It's also on Product Hunt

—Thanks, John

P.S. There'll be lots of new features added to Prod in the New Year, including Dark Mode, and a bunch of other stuff. Happy New Year!

iPhone Productity

According to Apple, the average iPhone user unlocks their phone 80 times a day1 — roughly once every 20 waking minutes — that's too many times.

Probably the best way to optimize your phone is to throw it in the sea — but it was expensive and your family would worry, so here's what you can do instead:


Your phone is designed to be distracting. Using bright colors is one way it steals your attention; notifications are an alarming red and app icons are rarely black and white.

The Center for Humane Technology suggests turning your phone grayscale to counteract this.

Settings → General → Accessibility → Accessibility Shortcut → Color Filters
This allows you to switch between grayscale and full color by triple clicking the home button.

In 2015 a video of a sea turtle with a straw stuck up its nose went viral.1

Many selfless people have since boycotted drinking straws, but for those who have a deep dislike of sea life, there's also a compelling and selfish reason to do so.

Drinking through a straw “minimizes the orthonasal olfactory hit,” — it makes the drink taste worse.2

When it comes to food and drink, the more aroma, the better. Anything that stops you from sticking your nose in the cup will dull the experience.

Don't let a straw block your nose.

Never Underline

Never use underlined text in any document, not even for links on a website. It makes your writing harder to read:

Underlining for emphasis was a necessity before the advent of word processors, as typewriters had no bold or italic lettering.

Not con­vinced? I in­vite you to find a book, news­pa­per, or mag­a­zine that un­der­lines text.1

Lemon Scent

A spritz of citrus can subconsciously inspire people to clean up. Paul Dolan writes in his book Happiness by Design:1

People who ate a biscuit after sitting in a cubicle with citrus air freshener pumped in made three times as many hand movements to clean crumbs off the table compared to those who were not exposed to this cleanest-smelling of scents.2

Line Length

The line length of any document; whether it's a book, a website, or a love letter, should be between two or three lowercase alphabets. Like so:


Shorter lines will make a big dif­fer­ence in the leg­i­bil­ity and pro­fes­sion­al­ism of your layout.1
