When your coins sit on two exchanges and a wallet, a simple question — what is it all worth today? — takes three apps and a calculator. A crypto portfolio app answers it on one screen. Describe your holdings and the numbers you care about, the AI agent builds a tracker that reads prices from a public price service, you check it in the emulator preview, and you download the APK. It tracks; it never trades.
What your crypto portfolio app will have
- Portfolio — total value, today's change and your overall profit or loss, in the currency you choose.
- Holdings — each coin with its quantity, current price, value, and profit or loss in green or red.
- Coin page — a price chart with 1-day, 7-day, 30-day and 1-year tabs, your transactions for that coin and your average buy price.
- Add transaction — buy, sell or transfer, with quantity, price, date and a note.
- Allocation — a pie chart of how your portfolio is split between coins.
- Watchlist — coins you follow but do not own, with their price and daily change.
Holdings and transactions are saved only on the phone. Prices come from the public price service when you are online, and the last ones are kept for when you are not.
Features you can ask for
- Several portfolios, such as Long term, Trading and Family.
- Stocks and funds tracked next to crypto.
- Price levels you set, highlighted each time you open the app.
- A Hide balances button for checking the app in public.
- A PIN lock on opening.
- A value history: a snapshot of your total saved each day you open the app, drawn as a line chart.
- Notes per transaction, such as the exchange or wallet it lives on.
Ideas to make it yours
The crypto and stock portfolio app guide goes deeper into transactions, average cost and charts. If you would rather see where your everyday money goes, the expense tracker app guide uses the same kind of charts for spending.
Get it on your phone
- Press Build this crypto portfolio app and sign in with Google. The agent builds the screens and connects the price data.
- Add a few test holdings in the emulator preview and check that the totals and the profit or loss add up.
- Ask for changes in plain words: "show the change as a percentage", "sort by value", "add a dark theme".
- Press Download APK and install it on your Android phone.
- For Google Play, build the signed version from the same menu; the APK builder page explains signing and uploading.
Check the numbers with one coin you know well before adding everything. If the average buy price matches your own records, the rest will too.
A tracker, not a trading app
This kind of app is deliberately limited, and that is what makes it safe to build and use. It never asks for exchange logins or wallet keys, so there is nothing for anyone to steal from it. It does not place orders, move coins or suggest what to buy; it simply multiplies what you hold by the latest price from a public price service and shows the result clearly. Prices can lag the market by a little, so the app shows when they were last refreshed. Keep your holdings on the phone, add a PIN lock if others use it, and remember that nothing in the app is financial advice. Within those limits it answers the question you actually open it for, in one glance. The AI app builder page explains how the builder works from first prompt to installed app.
Frequently asked
Can the app buy or sell crypto?
No. It is a portfolio tracker: you enter what you hold and it shows the value with prices from a public price service. It does not connect to exchanges, place trades or give financial advice.
Where are my holdings stored?
On the phone. The idea above needs no account and does not upload your holdings. Ask for a PIN lock if other people use your phone.
Can I track stocks too?
Yes. Ask for stocks and funds next to crypto; the app reads their prices from a public price service as well, and the allocation chart shows everything together.
Can it alert me when a price moves?
The app can highlight coins that crossed a level you set each time you open it. It does not watch prices in the background while the app is closed.
How do I install the tracker?
Press Download APK in the builder and install the file on your Android phone after allowing installs once. For Google Play, build the signed APK and AAB from the same menu.
