Crypto portfolio mockup: build a wallet overview whose numbers survive a calculator

People who ask for a fake crypto portfolio app want one of three things. If it is a screen for a demo, the work is mostly arithmetic: a total that is the sum of its rows, a change that fits the market, and a list in the right order. Here is how to get each one right.

Published: 19 September 2026 · Last reviewed: 28 October 2026

Three rules the screen has to obey

A wallet overview looks simple: a name, a big balance, a 24-hour change, a list. It also hides three constraints, and a viewer with a phone calculator can test all of them in seconds.

1. The total is a sum. It equals the rows added together, plus the cash row if there is one.
2. The change is derived. The header's dollar figure is the sum of the rows' own moves, and the percentage follows from it.
3. The order is not a choice. Once quantities and prices exist, the ranking by value is settled.

Break one and the screen stops being a prop for your video and becomes a puzzle for the audience. The rest of this page is about keeping all three true while you edit.

Work from dollars, then divide

People type quantities and then wonder why the total looks wrong. Reverse it. Decide what each row should be worth, then divide by the price. A unit of Bitcoin and a unit of Solana sit orders of magnitude apart, so a list where every row holds a similar quantity is the same number typed four times. Dividing hands you the unmemorable figures real balances have.

For the five built-in tokens we use live market prices, refreshed every four seconds; a custom token takes the price you type. Leave the screen open and the values drift with the market while your quantities stay put. The total moves on its own when you change one quantity.

Do not nudge the total itself. A round figure reads as set by hand, and odd cents are the signature of a real sum. If you need to land near a target, adjust a quantity until you are close, then stop and let the total be what it is.

Making the change figure agree

The day's change is computed, and both the header figure and the percentage come from the rows. The percentage is the dollar change divided by the balance before that change, which is the total minus the change, not the total. A worked example with made-up numbers: on a $31,000 balance, a +$155 change is +0.50%, because 155 divided by 30,845 is about 0.50 percent. Nothing else fits, so a +12% next to +$155 is a contradiction anyone can check on a phone.

The same rule runs per row. A row's dollar change is its value minus its value divided by one plus its percentage. Our simulator computes the header and the rows from the same percentages unless you type a total by hand. That override is where these screens fall apart: a balance that disagrees with the list below it makes the audience add rows instead of watching your product.

Shaping an allocation that holds up

Real portfolios are lopsided. A single position holds a third to a half of the value, two or three others make up most of the rest, and the tail trails off into rows worth a few dollars. Equal splits do not occur because nobody buys that way. A short recipe:

• One dominant holding, then a steep fall.
• A stablecoin somewhere in the middle, flat in the change column.
• A tail small enough to look forgotten.

Quantities should look accumulated. 503.39193 SOL is what a run of buys and fees leaves; 500.00000 is what a form leaves. Wallets print five decimals under a thousand units and two above, so the shape of the figure counts as much as its size.

Order, and why we do not re-sort for you

Ranking by fiat value, descending is the detail mockups miss most. Edit a quantity and leave the row where it was, and the list contradicts itself, with a 2,000 dollar position above a 15,000 dollar one.

A simulator can handle this in two ways: sort automatically or leave it to you. Ours moves rows by hand with arrows and never re-sorts. That is deliberate, and it makes you check the order after every edit.

Mixing chains in one column

Chains differ in native precision. Bitcoin settles in eight decimals, Ethereum in eighteen, Solana in nine and most stablecoins in six. No interface shows any of that: it applies one display rule to the whole column. A SOL-first screen, nine decimals included, is worked through in the Solana wallet simulator.

The five-and-two rule above gives 0.19453 BTC, 9.80977 ETH, 397.10732 SOL and 2,103.91 USDC in one aligned column. Switching convention from row to row is what makes a mixed list look hand-built.

Logos need the same discipline. Marks from different chains were never drawn together, so give them one diameter, a circular clip and a plate behind any mark that has none (crypto token icons: sizes, shapes and the traps).

How much fits on the phone

The phone's screen is the frame, and it does not stretch to fit your content. On a 6.1-inch iPhone, below the name, balance, change and cash row, four or five token rows show in full before the list slides behind the search bar. A twelve-token portfolio is a scroll, not a still image.

A pre-flight check before you film

Run this list once the screen looks finished. It takes a minute and catches nearly every slip we see.

1. Pick three rows and multiply quantity by price. Does each match the value on its right?
2. Add every row and the cash row. Does the sum match the headline, to the cent?
3. Read the change in dollars and percent together. Does the percentage fit the balance before the change?
4. Scan the value column from top to bottom. Is it strictly descending?
5. Look at the quantities as a column. Do any two look like the same number typed twice?
6. Count the decimals. Are they the same rule on every row, whatever the chain?
7. Check the logos for one size and one shape.

If you wait a minute before recording, repeat steps one to three. Live prices move, so a screen that added up a minute ago may differ by a few cents, which is exactly how a real wallet behaves.

Which tool for which job

As of October 28, 2026, searching for a fake crypto portfolio app turns up tools that do different things. Choose by the result you need.

• A screen for a video, a skit, a deck or a product demo. A portfolio mockup, like this page: quantities you type, live prices on five tokens, no account linked, no real money.
• Practice with pretend money. A paper-trading app. It gives virtual cash at market prices, and the holdings are the outcome of your trades.
• What a purchase would have gained. A what-if app. It calculates at real exchange rates and composes nothing.

The apps in the last two groups are real products with their own purposes. CustomCrypto: Crypto Simulator (App Store) offers virtual money at real market prices on 35+ coins with portfolio charts and profit and loss figures, rated 4.5 from 26 ratings when we read it on October 28, 2026. CryptoPlay: trade simulator (App Store) says no real trades are made and balances cannot be converted to real money. Fake Crypto Investor (Google Play) shows what a bitcoin purchase made now would gain or lose at real exchange rates, as read on October 12, 2026. In all three the portfolio is a result. In a mockup you pick it, so the arithmetic must hold on its own.

What this image is not

It is a mockup, never a record. No chain is read, no key exists, no exchange or wallet is linked, no money is held, and no amount corresponds to anything owned. Label it as a prop in anything you post. It is built for product demos and decks, tutorials and film props. It is not evidence of a balance, and presenting it as one is prohibited by the terms of use. Flexdger Wallet is one such app, made by us: a paid web app you add to your home screen, with no APK or IPA.
