Your portfolio,
reconciled to the cent.
BasisTrail unifies your Interactive Brokers activity and your crypto wallets into one audit-grade USD ledger — fees, FX, withholding and gas all accounted for. Then AI explains what moved, with sources.
100% read-only
IBKR + Base in one view
Every number traced to source
Your keys stay yours
One ledger
Broker truth and on-chain activity, finally in one place.
Every IBKR trade, dividend, fee and FX conversion sits next to every Base transfer and gas cost — normalized to USD, with the gaps shown instead of smoothed over.
- Net invested, realized & unrealized P&L
- Cash, fees and gas broken out
- Allocation, drift and sync quality
Holdings
See exactly where the weight sits.
A clean allocation donut and a sorted position table — by value, by P&L, or alphabetically — across every account, with cost basis and unrealized gains per asset.
- Donut allocation with per-asset weights
- Sort by value, P&L, or name
- IBKR and crypto wallets side by side
Ledger
Every transaction, grouped and legible.
A newspaper-clean ledger with date headers, color-coded flows, and one-tap filters by source, type, direction and asset. Anything that needs a second look is flagged for review.
- Search and filter across all sources
- Review flags for ambiguous events
- Dividends, fees, withholding all typed
Benchmark
Know if you're actually beating the market.
Compare your real performance against the S&P 500 or Nasdaq-100, side by side. Returns are contribution-adjusted, so adding money never masquerades as growth — you see the spread that's genuinely yours.
- Portfolio vs S&P 500 or Nasdaq-100
- Deposit-adjusted returns, not inflated ones
- Daily, weekly, and monthly windows
AI that reads your book
Ask anything. Get an answer with the receipts.
A daily brief in your chosen tone, plus a chat that actually knows your positions — every answer points to the exact part of your portfolio it used. No vague tips, no made-up numbers. Your broker tokens and wallet keys are never shared with the AI.
- Answers you can trace back to your own data
- Choose its voice: friendly, balanced, or deeply quantitative
- Private by design — your credentials never leave your account
Daily brief
Wake up to a brief, not a blank spreadsheet.
Each morning BasisTrail writes a short read on your book — what moved, why, and the one thing worth watching — in the tone you picked. Every figure is pulled straight from your own ledger, never invented.
- Week-to-date moves and the drivers behind them
- Flags real issues — idle cash, FX drag, review items
- Regenerate any time, or open chat to dig deeper
Reminders
Nudges worth keeping on.
Opt into the alerts that matter and skip the noise. BasisTrail pings you only when there's a reason — a fresh brief, a weekly review, a sync that's gone stale, or a gentle come-back nudge.
- Daily brief and weekly review
- Stale-sync reminders so data never drifts
- Every reminder is opt-in — never spam

FAQ
Straight answers.
Questions about using BasisTrail as a read-only Interactive Brokers portfolio tracker, crypto wallet tracker, cost basis tracker, or iPhone investment tracker? Start here.
Do you ever see my IBKR password or wallet keys?
No. BasisTrail uses an IBKR Flex Web Service token (read-only, you generate it) and public crypto wallet addresses. It cannot trade, move funds, or sign anything.
Is BasisTrail an Interactive Brokers portfolio tracker for iPhone?
Yes. BasisTrail is a native iPhone portfolio tracker built for Interactive Brokers users who want a read-only view of holdings, transactions, cash, fees, FX, and performance without giving an app trading authority.
Can BasisTrail track crypto wallet transfers, token balances, and gas fees?
Yes. BasisTrail is designed to bring crypto wallet activity into the same ledger as brokerage data, including balances, transfers, and gas costs, so users can inspect brokerage and on-chain activity in one place.
Does BasisTrail track cost basis and realized or unrealized gains?
Yes. BasisTrail is built to help users inspect cost basis, realized gains, unrealized gains, fees, cash, and FX across Interactive Brokers and crypto wallet activity. It supports advanced lot methods on paid plans once billing opens.
Why use BasisTrail instead of a spreadsheet or generic portfolio tracker?
BasisTrail is read-only, traces numbers back to source, and explains what changed with source-cited AI. It is built for investors who want audit-grade portfolio visibility instead of manually stitching together spreadsheets or relying on generic dashboards.
Who is BasisTrail best for?
BasisTrail is best for investors who want a read-only portfolio tracker for Interactive Brokers and crypto wallets, especially when they care about accurate holdings, transactions, fees, FX, cost basis, and explainable changes across both brokerage and on-chain accounts.
Where do I manage my plan?
Billing will be managed on the web, in your account here, once purchases open. Sign in with Apple in the app and your plan will link automatically with no extra steps.
What's different between the plans?
Demo access is deliberately narrow: one source, seven days of history, and no AI. Core unlocks unlimited tracking, exports, and advanced lot methods without the AI layer. Pro AI adds the full AI toolkit, including daily briefs, chat, transaction explanations, and data-quality audits. Monthly and Yearly only change billing cadence, and both are still marked coming soon until the App Store launch is approved.
What are AI credits?
AI credits apply to paid plans only. They cover the daily brief, chat, transaction explanations, and data-quality audits. Heavier requests use more, lighter requests use less, and BasisTrail calculates that budget from real model usage so it stays fair and sustainable. Your balance resets every month.
Is the AI giving financial advice?
No. It explains your own data and flags issues, citing the exact sources. It never tells you to buy or sell, and your credentials are stripped before anything reaches the model.
Can I cancel?
Once billing opens, you’ll be able to cancel anytime from the billing portal and keep your data accessible on the Demo tier.
