Compare Mode: How to Put Two Products Head to Head

You are standing in a store, or more likely sitting on your couch scrolling through a product page, and you have narrowed it down to two options. Maybe it is two pairs of headphones -- one at $80 and one at $200. Maybe it is two winter jackets, two coffee machines, or two laptops. The cheaper one saves you money upfront. The more expensive one promises better quality, more features, or longer durability.

Your instinct says go cheap. The marketing says go premium. Your friend says one thing, the reviews say another, and somewhere in the back of your mind a voice is whispering "just get both."

This is the exact moment Skip or Buy's Compare Mode was built for. It takes the guesswork, the gut feelings, and the marketing noise out of the equation and replaces them with one clear, objective number for each option: cost per use.

What Compare Mode Does

Compare Mode lets you enter two items side by side and see their cost per use calculated in parallel. You input the name, price, category, and expected usage frequency for each product, and the app instantly shows you which one delivers more value per use -- regardless of which one has the lower price tag.

This sounds simple, and it is. That simplicity is the point. The hardest part of comparing two products is not finding information -- it is cutting through the overwhelming amount of irrelevant information to find the one metric that actually matters for your wallet. Compare Mode does that cutting for you.

How to Use Compare Mode: Step by Step

Setting Up Your Comparison

Open Skip or Buy and switch to Compare Mode. You will see two input areas side by side -- one for each product.

For each item, enter the following:

• Item name: Whatever helps you identify the product. "Sony headphones" and "AirPods" works fine. You do not need model numbers.
• Price: The actual price you would pay, including tax if you want precision. If one item is on sale, use the sale price.
• Category: Choose from the 33 built-in categories. Both items should usually be in the same category, though there are exceptions (more on that later).
• Usage frequency: How often you honestly expect to use the item. This is the most important input, so take a moment to think about it realistically.

Reading the Results

Once both items are entered, Skip or Buy calculates and displays the cost per use for each. The presentation makes the comparison immediately clear -- you can see at a glance which item delivers better value.

But the raw numbers are only part of the story. Each item's cost per use is also evaluated against the category benchmark, so you can see not just which item is better relative to the other, but whether either item is a good value in absolute terms.

This is a crucial distinction. Sometimes neither option is worth buying. Sometimes both are excellent value. Compare Mode shows you the full picture, not just a winner and a loser.

Real-World Comparison Scenarios

The best way to understand Compare Mode's power is to see it applied to the kinds of decisions people actually face. Here are five scenarios where it transforms an agonizing choice into an obvious one.

Scenario 1: Budget vs. Premium Headphones

• Option A: $60 wireless earbuds, expected lifespan of 1 year with daily use (365 uses). Cost per use: $0.16.
• Option B: $250 over-ear headphones, expected lifespan of 4 years with daily use (1,460 uses). Cost per use: $0.17.

The result is striking. Despite a $190 price difference, the cost per use is virtually identical. In this case, your decision should come down to preference -- comfort, sound quality, portability -- because both options deliver comparable value per use. The "expensive" headphones are not actually more expensive in any meaningful sense.

Scenario 2: Fast Fashion vs. Quality Basics

• Option A: $25 t-shirt, worn 15 times before it loses shape. Cost per use: $1.67.
• Option B: $75 t-shirt from a quality brand, worn 120 times over 3 years. Cost per use: $0.63.

The premium shirt costs three times more at the register but less than half as much per wear. This is the pattern Compare Mode reveals over and over in the clothing category: the "affordable" option is frequently the more expensive choice when you account for how long it actually lasts.

Scenario 3: Kitchen Appliance Showdown

• Option A: $40 basic blender, used twice a week for 2 years (208 uses). Cost per use: $0.19.
• Option B: $350 high-end blender, used four times a week for 8 years (1,664 uses). Cost per use: $0.21.

This one is closer than most people expect. The high-end blender has a marginally higher cost per use despite its dramatically longer lifespan, because the budget option is so cheap upfront. The decision here legitimately depends on whether you value the extra features and durability enough to justify a similar cost per use at a much higher total price. Compare Mode gives you the clarity to make that call without second-guessing.

Scenario 4: Gym Membership vs. Home Equipment

This is an interesting case where the two options are in different categories but serve the same purpose.

• Option A: $50/month gym membership, used 12 times a month for a year (144 uses). Cost per use: $4.17.
• Option B: $600 set of home workout equipment, used 4 times a week for 3 years (624 uses). Cost per use: $0.96.

The home equipment wins by a wide margin on cost per use, but only if you actually stick with the projected usage for three years. Compare Mode shows you the math; your self-knowledge tells you whether you will follow through.

Scenario 5: Tech Upgrade Decision

• Option A: $800 mid-range phone, replaced after 2 years of daily use (730 uses). Cost per use: $1.10.
• Option B: $1,200 flagship phone, kept for 3 years of daily use (1,095 uses). Cost per use: $1.10.

Identical cost per use. When Compare Mode produces a tie like this, it is genuinely liberating -- you can choose based on preference, features, or cash flow without worrying about which is the "smarter" financial choice, because they are both equally smart.

Advanced Compare Mode Strategies

Once you are comfortable with basic comparisons, here are some ways to get even more out of the feature.

Compare Against What You Already Own

One of the most underrated uses of Compare Mode is comparing a potential new purchase against something you already have. If you are thinking about upgrading your laptop, enter both your current laptop (with its original price and your actual usage over its lifespan so far) and the new one you are considering. This reframes the question from "Should I buy this?" to "Is this upgrade actually better value than what I already have?"

Often, the answer is no -- your current item is delivering excellent cost per use because you have already amortized most of the price. Seeing that clearly can save you from unnecessary upgrades driven by novelty rather than need.

Test Different Usage Scenarios

If you are uncertain about how often you will use something, run the comparison twice with different usage estimates. Compare the two products assuming optimistic usage, then compare them again assuming realistic usage.

If one product wins in both scenarios, the decision is clear. If the winner changes depending on the usage assumptions, that tells you the decision is highly sensitive to your actual behaviour -- which means you should be conservative in your projection and lean toward the option that wins under realistic use.

Factor In Replacement Cycles

For items that wear out and need replacing, think in terms of total cost over a fixed time period. If you would go through three cheap blenders in the same time you would own one premium blender, the comparison should be $120 (three cheap blenders) versus $350 (one premium blender) over the same usage period.

What Compare Mode Will Not Do

It is worth being honest about the boundaries of any tool. Compare Mode gives you the financial comparison -- which item delivers more value per pound or dollar spent. It does not account for:

• Subjective quality differences like how something feels, sounds, or looks
• Emotional value -- a gift from someone special has value no calculator can measure
• Ethical considerations like sustainability, fair labour practices, or environmental impact
• Opportunity cost -- what else you could do with the money

These factors matter, and they should absolutely influence your decisions. But they are best considered after you have the financial picture clear, not instead of it. Compare Mode gives you the objective foundation; you add the subjective judgement on top.

Share Your Comparison

After running a comparison, you can use Skip or Buy's Share Cards feature to create a clean, visual summary of the comparison and share it with someone else. This is particularly useful when you are making a joint purchase decision with a partner, roommate, or family member. Instead of trying to explain the math verbally, you can send a card that makes the case visually.

It also works well for settling friendly debates. Next time someone insists the expensive option is "a waste of money" or that the cheap option is "false economy," run the comparison and share the result. The numbers speak for themselves.

The Bottom Line

Every purchasing decision between two options is, at its core, a value comparison. Which item gives you more for your money? That question has an objective answer, and Compare Mode calculates it in seconds.

You do not need to agonize in store aisles. You do not need to read forty reviews searching for a consensus that does not exist. You do not need to flip a coin or go with your gut and hope for the best. You need two prices, two usage estimates, and ten seconds.

The app is free to try for 3 days, then just £3.99/week or £39.99/year. No ads, no data collection. Your comparisons stay on your device, completely private and completely offline. It is a tool that works for you and answers to no one else.
