The bottom line
Validate an app idea by putting it on a simple mobile-friendly one-page site and asking real people what they love and hate about it. Talking to your target users early shows you what they need before you spend months building.
Key takeaways
- Building without talking to real users is the biggest mistake in launching an app. 5:54
- Barnett's first startup, First Roots Media, let independent musicians sell or share music and track how far fans spread it.
- He built it around how he liked to download music as a fan, spoke to barely any artists, and the project was abandoned.
- A single mobile-friendly page makes an idea easy for strangers to judge. 6:24
- The page covers what it is, who it's for, how it works and what it can be used for.
- A beginner can build it with a drag-and-drop tool like Wix, using napkin sketches of a few screens.
- Asking what people love, what they hate and what they want next draws out honest answers. 7:36
- The words love and hate stir up emotion, so people feel invested and give a true response.
- Asking each respondent for introductions grows your pool of testers. 8:10
- Naming the person who recommended you can dramatically raise your response rate.
- Cold outreach on Instagram or Twitter is tedious at first, so keep each message personal and say why that person's feedback matters.
- Market research on competitors and names should follow the feedback. 9:31
- Compile the answers in a spreadsheet and look for the positives.
- If a similar product exists, study why it isn't succeeding and focus on what you can do better.
It's so hard to find five minutes of someone's time, so we have to make it easy for people to validate things.

Chapter summaries
0:00 Why Leo goes by Leo J Barnett
Leo added the J to his name to keep his film and TV work apart from his career in apps.
- Extra work in film and TV paid for his startup projects. 1:16
- He worked as an extra for about two and a half years.
- Before that he did freelance jobs like gardening and fencing to pay the bills.
- Screen credits tend to bring stage names that feel glorified and over the top.
- He wanted a plain name, so he settled on Leo J Barnett.
- He has stepped back from film and TV, though he appears in The Crown.
2:30 Balancing odd jobs with a startup
Low-pay, flexible work leaves room to think and design, but the hours are long and the cash is thin.
- Repetitive jobs give you time to think up ideas. 3:27
- Painting hundreds of walls the same colour leaves your mind free.
- He wrote ideas down as they came and moved them forward.
- Low pay means more hours of work for the same money, so there is less time overall.
- The stress is real, and he calls it hard to do.
- He designed apps wherever the work took him. 3:56
- On a Pokemon film set he sat in a tent designing apps between scenes.
- Client messages kept coming in while he was on set.
- Days could start at 4:00 a.m. and end around 9:00 p.m.
- Freelance work gave him no say over his hours, so he kept both jobs in his head at all times.
5:47 One short page makes feedback easy to give
A single page removes the excuses people have for not reviewing an idea.
- One page is quick enough that nobody can say no. 6:53
- Five minutes of someone's time is hard to get, so the page has to be easy to judge.
- Send the page to target users through Twitter and Instagram.
- Validating is easier today because there are many ways to reach a target audience 6:15.
- The page opens with a short intro, then covers what it is, who it's for and how it works.
8:00 Every respondent opens the door to more
Each person who answers can bring a network of new testers.
- Ask each respondent who else should see the idea. 8:00
- Find a perfect target, such as an influencer on Instagram, and ask for their contacts once they reply.
- Everyone has connections, and friendly people are happy to share them.
- The approach: Hey Jess, Sarah just recommended me to speak to you.
- Referrals work like a snowball, spreading through the network or community around your first core responders.
9:25 Check the idea is new and show what it's for
Once feedback is in, confirm the idea is fresh, then inspire people with use cases and images.
- Make sure the idea hasn't been done before. 9:27
- Look for the positives in the answers.
- Check whether the name is already taken.
- If a rival exists, ask why it isn't taking off and aim to do that part better.
- The data goes into one spreadsheet, then you move on.
- Showing use cases and images inspires people more than a plain label. 10:00
- The Reelshot site gives a quick headline for a new feature, then a "what is it for" line.
- Listing uses doesn't pigeonhole the product. It prompts people to think of their own, like I can also use this for X, Y and Z.
- Ask what would trigger someone to use a product like this 10:43.
- A few images help even if they don't show your app, such as a character or object people remember 11:01.
