My phone used to be a shopping mall. Amazon, a couple of fast-fashion apps, a marketplace app, a bookstore app — all sitting there on my home screen, all one thumb-tap away from my wallet. I told myself I only opened them when I needed something. My bank statements told a different story.

So I ran an experiment: delete every shopping app for 30 days. Not “use them less.” Gone. Here’s what happened, with the numbers.

The Rules

Simple ones. On day one, I deleted every app whose primary purpose was selling me things: Amazon, two clothing apps, the bookstore, the marketplace app. I kept the grocery delivery app — food is food — but everything else went.

The rule for the month: if I needed something, I had to buy it on a desktop browser, deliberately, or go to a physical store. No thumb-tap purchases. No “just browsing” at midnight.

I also wrote down every non-grocery purchase I made during the month, with the price. Same as I’d done the month before, so I could compare honestly.

The Month Before: $487

In the 30 days before the experiment, my non-grocery discretionary spending totaled $487. Here’s the breakdown:

• $164 on clothes I didn’t need (two hoodies, a pair of pants, socks I already owned)
• $89 on books (three paperbacks, one of which I still haven’t opened)
• $71 on kitchen gadgets (a “precision” pour-over kettle I used twice)
• $163 on miscellaneous: phone case, cables, a backpack “upgrade,” things I can’t fully reconstruct

Roughly a third of it — maybe $150 — was stuff I actually needed or still use. The rest was thumb-tap spending: boredom, not necessity.

The Experiment Month: $193

During the 30 days without shopping apps, I spent $193 on non-grocery purchases:

• $68 on a pair of running shoes (my old ones had a hole — genuine need, bought on desktop after a week of thinking about it)
• $45 on a birthday gift
• $80 on household basics (light bulbs, cleaning supplies, a plunger — glamorous)

That’s a $294 difference in one month. Annualized, it’s over $3,500.

What Actually Changed

The money is the headline, but the mechanism is the interesting part.

Friction works. Every dumb purchase I’d made the month before had the same shape: see it, tap it, own it, all within 90 seconds. Removing the apps didn’t remove my ability to buy things — it added about five minutes of friction. Open the laptop, type the URL, log in, find the thing. Five minutes is nothing, except it turns out it’s everything. Roughly 80% of my impulse purchases died somewhere in those five minutes. I just… didn’t bother.

Boredom was the real app. The first week was the hardest, and not because I needed anything. I’d reach for my phone in line at the bank, on the couch at 11pm, waiting for pasta water to boil — and the little dopamine slot machine wasn’t there. By week two, I’d stopped reaching. The habit wasn’t shopping. The habit was fidgeting, and shopping apps had monetized my fidgeting.

“Just browsing” is never just browsing. I used to tell myself I was comparison shopping, doing research. The numbers say otherwise: in the month before, I “researched” my way into $487. During the experiment month, the one genuine need (running shoes) got a full week of deliberate desktop research and cost $68. Real research is slow and boring. Browsing is fast and expensive.

What I Kept After the 30 Days

The experiment ended three months ago. Here’s what’s stuck:

1. The shopping apps never came back. All of them. If I need something from Amazon, desktop browser, deliberate session, done. I buy maybe twice a month now instead of twice a week.
2. The 5-minute rule. Anything I want goes on a notes list. I wait 48 hours before buying. Most items never make it off the list.
3. The spending log. I still jot down non-grocery purchases. It takes 30 seconds and it keeps the number honest. Last month: $211.

The Honest Caveats

This won’t work the same for everyone. If you genuinely do most of your household shopping on your phone because of mobility or time constraints, deleting apps just moves the spending to the mobile browser. The trick isn’t the deletion — it’s the friction. Find whatever adds five deliberate minutes between impulse and purchase for you.

And I’m not precious about it. I still buy things. I like things. The point was never to spend zero — it was to stop spending $300 a month on fidgeting.

Try It

Delete the apps tonight. Not forever — 30 days. Keep a simple log of what you spend. Compare it to last month’s statements. If the gap doesn’t surprise you, reinstall everything and forget I said anything.

But I’m guessing it will surprise you.
