Show HN: Turn impulse buys into dream investments

https://www.nopeit.app
14•pjcodes•6mo ago
Hi HN, I’ve always struggled with impulse buying—that late-night Amazon scroll or the "deal" that's too good to pass up. I realized I was trading long-term goals for short-term dopamine hits. The core problem is the frictionlessness of modern e-commerce.

To fight back, I built Nope It. It’s not just another budgeting app. It's a PWA designed to interrupt the impulse loop at the critical moment.

How it works is based on a few key psychological principles:

Forced Pause (The Cooldown): Inspired by Daniel Kahneman's "Thinking, Fast and Slow," the app introduces a mandatory 24-hour cooldown on any logged impulse. This shifts you from impulsive "System 1" thinking to deliberate "System 2" thinking.

Cost Re-framing (Work Hours Psychology): It immediately translates the item's price into a more tangible metric: This $80 gadget costs you 4 hours of your work. This technique, known as "opportunity cost visualization," makes the trade-off much more real.

Goal Redirection: Instead of just saying "no," the app encourages you to immediately contribute the saved amount to a pre-defined Wishlist Goal (e.g., "Vacation Fund," "Down Payment"). This replaces the lost dopamine from buying with the positive feeling of making progress.

The Tech:

It's built as an enterprise-grade behavioral platform, but the front-end is a simple, fast Progressive Web Application (PWA) so there's nothing to install. It's accessible on any device, instantly.

I wanted to turn a personal weakness into a strength and thought others might find it useful too. I'm here to answer any questions about the psychology, the tech, or the journey.

Would love to get your feedback!

How is the app triggered? There is a graphic that makes it seem like the app can detect impulse buys:

iPhone 16 Pro Max $1,625 IMPULSE DETECTED

I think this is a good idea I'm just not convinced I would manually interrupt my impulse buys to pull up the app to stop my impulse buys. How does the app introduce friction to the purchase process?

pjcodes•6mo ago
For the time being, the "IMPULSE DETECTED" graphic is more of a conceptual representation than a real-time detection function.

The app currently depends on you manually recording a "impulse moment," which is essentially any time you catch yourself on the verge of making an unnecessary purchase. The idea is to create just enough friction to get you to stop doing things automatically. Launch the app → input the item → feel the 24-hour timer and let work-hours cost hit you → ideally, choose to skip and "pay yourself" instead.

Having said that, I'm evaluating out potential future integrations because many users have requested automatic impulse detection or more intelligent nudges.

So short answer: currently user-triggered, future versions will make that trigger smarter and more automatic.

Really appreciate you asking. This kind of feedback helps me prioritise what to build next

> Cost Re-framing (Work Hours Psychology): It immediately translates the item's price into a more tangible metric: This $80 gadget costs you 4 hours of your work. This technique, known as "opportunity cost visualization," makes the trade-off much more real.

I already do this automatically myself but this only makes me more likely to buy stuff I want. Because many things are so crazy cheap that the time you need to work for them is really not a lot.

Also, the example on the website says 2.1 weeks of work for $217 sneakers. Is the person on the example earning $400 per month or is the calculation different (for example only considering expendable income)?

rconti•6mo ago
I had this problem when I started budgeting/tracking my money more closely. Turns out I don't spend ENOUGH money on my hobbies! :D
pjcodes•6mo ago
That’s honestly such a good takeaway. Sometimes tracking your money doesn’t reveal overspending; it shows that you’ve been neglecting the parts of your life that bring you joy.

You’re exactly the kind of person I created this for. I’m not against spending at all. The goal is to spend with purpose. When you do buy something, especially related to your hobbies, it should feel earned, guilt-free, and in line with what you truly value not just random temptations from scrolling.

Fire-Dragon-DoL•6mo ago
I discovered the same, my wife did not accept it yet. Then i proceeded to buy 5 boars games and made the family happy, and we still have leftover budget!
pjcodes•6mo ago
That's a completely valid point, and I’ve heard similar feedback from many early users. I recommend, and I personally have started doing this, that you plug in your disposable income instead of your total salary.

Disposable income is what you have left after paying for essentials like rent, groceries, commuting, and bills. It’s basically the money available for non-essential purchases. This gives you a more realistic hourly rate and makes you think more about opportunity costs. For example, that $80 gadget could be taking a much bigger chunk of your free cash than it seems at first.

To clarify, in the current free plan, users can enter their annual income. However, the work-hours psychology is based on a default average of about $50k USD. This varies by currency and country, so in this case, like the sneakers example, it translates to about 2.1 weeks.

In the premium version, the app uses your actual income or disposable income, if you prefer, so it becomes much more personalized and precise.

As a thank you to early adopters, I’m offering free weekly premium access to gather feedback and improve the app. Let me know if you’d like to try out the personalized version.

rconti•6mo ago
Under cost re-framing and goal redirection, it might be neat to add something like "how much this amount of money would net you in 5/10 years at 7% growth" for example. (Ties into the down payment category, perhaps).
pjcodes•6mo ago
Believe me, this is such a great idea that I recently received exactly the same feedback.

It's already on my roadmap because the user indicated that it would be effective to demonstrate "what this skipped purchase could grow into in 5/10 years at X% compounding."

The concept would be: rather than merely saving $80 today, demonstrate that, at a 7% annual growth rate, it will reach $157 in ten years, making the "opportunity cost" even more difficult to overlook (and much more motivating if you're saving for things like a down payment).

You have no idea how much these suggestions are helping me shape the next wave of features, so please keep coming.

I don't see why I would need an entire webapp to divide a price tag by my hourly wage.
x-complexity•6mo ago
You're rationally thinking about this, not the impulsive state someone will be in when impulse buying (where math rarely occurs, if ever).

Visually showing alternatives to the impulse buyer adds friction between the user & the purchase, and when compared to the original seamless shopping experience, that's enough to slow down impulse purchases.

pjcodes•6mo ago
Thanks, much appreciated!
pjcodes•6mo ago
True enough, I wouldn't require an entire webapp if it only involved dividing a price by my hourly rate.

As x-complexity pointed out, the true value arises when I'm not acting rationally. I won't open a calculator in the heat of the moment, but I will open something that’s designed to interrupt me, slap me with the true cost, start a 24-hr timer, and then redirect the money somewhere meaningful if I choose to skip.

It’s less about the calculation, and more about the friction + psychology + follow through. I basically built the app to be the version of me who shows up when the rational version has left the chat

iJohnDoe•6mo ago
Since I know I won’t build a financial app, I offer this idea to everyone.

You know those apps that round up your transactions on your debit card and it builds up savings over time? Do this same exact concept but have the money that builds up be used to pay down credit card debt. Even if it’s not much, any extra dollar makes a difference. To make the app really effective it needs to be able to pay the credit card directly.

pjcodes•6mo ago
That’s a great idea.

Currently, my app focuses on preventing unnecessary spending and directing that "almost spent" money into savings, but I'm definitely noting this feedback.

Connecting directly to the card and pushing payments would require a larger integration project. However, this is exactly the type of feedback I need for planning my roadmap.

gautamjain0111•6mo ago
Hey, apps that focus on preventing impulsive buying offer real value. They boost financial awareness, reinforce good habits, and provide useful decision-making tools.

However, a truly effective app should make its most helpful features accessible without aggressive upselling and should provide deeper, customizable reflection on spending choices.

For anyone frequently struggling with impulsive buying, these apps offer a solid starting point. Just be mindful of the cost-to-benefit tradeoff.

pjcodes•6mo ago
The viewpoint you shared is great because applications need to build trust through initial valuable experiences rather than hiding features behind paywall.

I’ve been really intentional about that: the core features (logging impulses, the 24-hour cooldown, and the “allocate to your dream investment” system) are fully free, with no upsell wall getting in the way.

The premium feature like personalized work-hour calculations, unlimited impulse logging, unlimited dreams and deeper goal tracking are there mostly for users who want to go deeper.

I definitely don’t want it to feel like a trap. I'm actually giving out free weekly premium access to early users so I can get feedback on what’s genuinely useful (and what’s just noise).

gautamjain0111•6mo ago
Meanwhile a suggested feature you can consider No Spend Challenge Tracker - The app includes a calendar where users can visually track no-spend days, helping to reinforce positive habits and also can collect reward points.
pjcodes•6mo ago
This seems like an awesome idea. I am adding this to my roadmap, you might see it in the app soon. Thanks
pjcodes•6mo ago
It is so good to see everyone’s feedback to this point and I hope you understand I am still creating things based on your thinking and feedback.

Quite a number of users suggested that it makes more sense to plug in disposable income instead of your total salary, the income left after essentials like rent, groceries, and other bills, because it gives a much more realistic work hour cost of an impulse buy.

Does that make sense to everyone else and do you think the calculation inside the application should, by default, rely on disposable income instead of your annual salary?

I would also like to state that as appreciation to all users testing the application at this early stage, I will begin to award users with premium access for a week so that users are able to experience the complete version(including personalised work-hours logic) of the application, so you can just go to Settings and put in your disposable income and test the app out.

I would really appreciate your feedback on this concept to allow me to work on the idea and implement it as soon as possible.

anmolkala•6mo ago
This is such a thoughtful idea. The cooldown and work-hour reframing hit hard and really make you think before spending. You can tell it’s built from personal experience.

Since you’ve already got reflections and streaks in place, a simple browser extension could be an awesome next step. Something that gently pops up when you're about to buy, just to break that autopilot.

Love how real this feels. It’s something a lot of us need.

pjcodes•6mo ago
Thanks a ton. Honestly, I’ve always been user zero of this app. I went through a bunch of versions before launching because I wanted it to create just the right amount of friction for anyone who struggles with impulsive buying (like I did).

And that’s a great suggestion. I did think about building a browser extension early on, but purposely kept things simple until I could get real feedback from people actually using it. The goal isn’t to build more features, it’s to build something that genuinely helps people grow their wealth so I really appreciate ideas like this and will definitely keep it on my list.

pjcodes•6mo ago
I’d genuinely love to hear the feedbacks. For those of you who’ve tried the app how’s the experience been so far? Has it helped you pause, reflect, or rethink any of your impulse buys?

Any feedback, big or small, would mean a lot. I’m building this to be truly useful, and your input helps shape what comes next
