The Trezor phishing blast in early September pushed a lot of holders back toward hardware wallets. It also pushed them away from checking balances inside the wallet itself. Every extra tap inside a signing device is another chance to approve something you did not mean to approve. The safer pattern is a read-only tracker on the phone, an app that watches balances across chains without ever touching your keys.
We tested seven Android portfolio trackers. All support view-only wallet imports, none of them require you to enter a seed phrase, and each one earns its place with a distinct trade-off. Ranked by how quickly they refresh multi-chain balances and how honest they are about their subscription upsells.
What to look for in a portfolio tracker
- Read-only import. Address or exchange API key, never a seed phrase. Any app that asks for the seed is fraudulent.
- Multi-chain coverage. Bitcoin, Ethereum, Solana, Layer 2s, and the current wave of Cosmos chains at minimum.
- Exchange API keys, not passwords. The tracker imports read-only keys with no withdrawal permission.
- Real-time price updates. Five-minute refresh is the baseline, real-time is a paid tier for most apps.
- Tax-friendly export. CSV of every transaction, tagged by source, saves hours at tax time.
- No custody. The tracker never holds your assets. If it advertises staking or trading, understand the trust shift.

The apps
1. Coin Stats, the overall pick
Coin Stats covers the widest range of chains and exchanges without asking for a seed phrase at any step. Add wallets by address, exchanges by read-only API key, and DeFi positions through the built-in connector. The mobile app matches the web dashboard, so you get the same view whether you check from a laptop or a phone. Portfolio-level alerts trigger on price moves, wallet activity, and DeFi position health.
Where it falls short: The free tier caps wallets and exchanges hard enough that most active users hit the ceiling within a week.
Pricing:
- Free: 10 wallets, 2 exchanges.
- Paid: Starts around 3.49 dollars a month annualised for Pro.
Platforms: Android, iOS, Web, Chrome extension.
Bottom line: The best starting point unless you know you want a specialist tool.
2. Delta Investment Tracker, the clean UI
Delta is owned by eToro and, of the mainstream trackers, has the sharpest UI. Widgets are legible without a tap. The multi-portfolio setup makes it easy to separate long-term holdings from trading capital. Exchange sync is fast, and the CSV export is clean enough to hand to an accountant.
Where it falls short: The paid tier price is the highest in this list for what you get. The eToro parent brand may nudge you toward their exchange.
Pricing:
- Free: Basic tracking with limited alerts.
- Paid: Around 4.99 dollars a month for Pro.
Platforms: Android, iOS, macOS, Windows.
Bottom line: Pick this for the interface polish, not the price.
3. CoinMarketCap, price data first
CoinMarketCap started as a price aggregator, and the tracker features grew on top. The strength is data quality: reference prices, historical charts, and exchange volume that other trackers cite as their source of truth. The portfolio side is enough for casual holders, though it lacks the DeFi-position depth of Zerion or Zapper.
Where it falls short: Ads on the free tier are visible on almost every screen. The Ad-free tier is a fair upgrade but not obvious in the pricing page.
Pricing:
- Free: Full price data with ads.
- Paid: Ad-free tier.
Platforms: Android, iOS, Web.
Bottom line: Great for reference data. Adequate as a portfolio tracker.
4. CoinGecko, independent data feed
CoinGecko is the private-company alternative to CoinMarketCap and the reference feed for many DeFi dashboards. The Android app carries the same feature list plus a lightweight portfolio view. If you want a free tracker that is not owned by an exchange conglomerate, this is the shortlist.
Where it falls short: Portfolio side is basic. No DeFi position parsing beyond token balances.
Pricing:
- Free: Full data, price alerts.
- Paid: Ad-free tier around 2.99 dollars a month.
Platforms: Android, iOS, Web.
Bottom line: Better data feed than CoinMarketCap, thinner portfolio side.
5. Zerion, DeFi-native
Zerion started as a DeFi dashboard and grew a mobile app on top. Paste an EVM address and the app parses every DeFi position: LP tokens, staked assets, yield farms, and NFT floors. The read-only mode is safe. The optional Zerion Wallet is a separate opt-in and does not enable itself just because you installed the app.
Where it falls short: EVM-focused. Bitcoin and Solana coverage is thin compared to Coin Stats.
Pricing:
- Free: Full DeFi tracking across supported chains.
- Paid: Optional Pro tier for advanced alerts.
Platforms: Android, iOS, Web.
Bottom line: Best in class for DeFi-heavy portfolios. Weaker for straight bag holders.
6. Zapper, bundled DeFi positions
Zapper covers similar ground to Zerion with a stronger focus on bundling: LP tokens, vault deposits, staking positions, and NFT holdings all roll into a single “bundle” the app can watch across wallets. Useful when a portfolio spans multiple addresses and multiple protocols.
Where it falls short: Fewer chains than Coin Stats. Occasional lag on brand-new DeFi protocols.
Pricing:
- Free: Multi-wallet bundling, basic tracking.
- Paid: Optional Pro subscription.
Platforms: Android, iOS, Web.
Bottom line: Great when the portfolio lives across many wallets and many protocols.
7. Kubera, portfolio across asset classes
Kubera is the odd pick here because it tracks crypto alongside bank accounts, brokerage holdings, real estate, and even domain names. If you want a single net-worth number that includes crypto without living in crypto tools, Kubera is the app. The read-only wallet import stays on the safe side of the seed-phrase line.
Where it falls short: The price. Fifteen dollars a month is the highest tier here, and there is no free plan beyond the trial.
Pricing:
- Free: 14-day trial.
- Paid: 15 dollars a month.
Platforms: Android, iOS, Web.
Bottom line: The right pick when crypto is one asset class among many, not the whole portfolio.
How to pick the right one
- You are not sure yet: Coin Stats. Widest coverage and the best default experience.
- DeFi positions are the main thing: Zerion or Zapper. Both are free and both parse LPs, vaults, and staked positions.
- You already trust CoinMarketCap or CoinGecko for prices: Their own apps double as portfolio trackers.
- You want a beautiful UI and price is not a concern: Delta.
- Crypto is a slice of a bigger picture: Kubera.
FAQ
Should a portfolio tracker ever ask for a seed phrase?
No. Never. A read-only tracker takes an address for on-chain balances and a read-only API key for exchange balances. If any app asks for a 12- or 24-word seed, it is a scam.
What is the safest way to add an exchange to a tracker?
Generate an API key with view-only permissions, no trading, no withdrawal. Rotate the key if you ever suspect exposure.
How often should the tracker refresh?
Five minutes is enough for holdings-focused use. For active trading you want real-time, and that is usually a paid tier.
Can these apps do my crypto taxes?
Most export a CSV that a dedicated tax tool can import. The tracker itself is not a tax product for anything beyond the simplest bag.
Is a hardware wallet safer than a portfolio tracker for checking balances?
They solve different problems. A hardware wallet is safest for signing transactions, but you should not need to plug it in just to see a number. A read-only tracker on the phone is the right daily-driver view.
