Summa Ledger · iOS App

Built for the way you live and work

Every feature is designed for anyone who wants clarity, speed, and complete privacy over their finances — freelancers, side hustlers, and everyday budgeters alike.

Core

Expense Management

The foundation — fast, flexible, and fully offline.

Expense Logging

Add expenses in seconds. Set the amount, category, date, and notes — then get back to work. Full search and filter across your entire history.

Custom Categories

Organize expenses using built-in Schedule C categories or create your own. Every category maps cleanly to tax deduction types.

Receipt Capture & OCR

Photograph a receipt and attach it to any expense. Basic OCR is free — upgrade to Premium to let on-device AI automatically extract the merchant, date, and amount for you.

Smart Search & Filters

Instantly find any expense by keyword, category, date range, or amount. Multi-select filters let you slice your data any way you need.

Mileage

Never miss a deduction

The IRS allows a standard mileage deduction for business travel. Summa Ledger makes it effortless to claim every mile.

Trip Logging

Log any trip with start/end locations and distance. Add a purpose and client — everything you need for a clean IRS-compliant mileage log.

Automatic Deduction Calculation

Summa Ledger applies the current IRS standard mileage rate automatically. See your total deduction value update in real time as you log trips.

Mileage Reports

Export a complete mileage log in CSV or PDF — formatted exactly as tax preparers and accountants expect to receive it.

Purpose Tracking

Tag each trip as Business, Medical, Charity, or Personal. Different trip types use different IRS rates — Summa Ledger handles the math.

Reports & Sharing

Clarity at tax time and beyond

Powerful reports and seamless accountant sharing make year-end easy.

Spending Charts

Visual breakdowns by category, month, and year. Spot trends and outliers at a glance — whether you're tracking business expenses, a side hustle, or just your monthly budget.

CSV & PDF Export

Export your expenses and mileage logs as CSV for spreadsheets or PDF for sharing. Filter by date range before exporting to get exactly the data you need.

iCloud Sharing & Peer Collaboration

Share a read-only live view with your accountant, or invite a trusted person to collaborate in real time — like iOS Notes, but for your finances. All powered by iCloud, no extra apps needed.

Local Storage, Encryption & Biometric Lock

All data is stored in an encrypted SQLite database using iOS Data Protection. Lock the app with Face ID or a passcode for an extra layer of security. Your finances are never sent to any third-party server — iCloud is the only optional connection, entirely within Apple's ecosystem.

AI & Intelligence

Private AI that actually works

Every intelligent feature runs entirely on your device — no internet required, no data sent to third-party servers.

AI Receipt Scanning

On-device OCR powered by ML Kit extracts text, then a DistilBERT NER model identifies the merchant, grand total, tax, tip, and date with per-field confidence scoring. High-confidence fields auto-fill the form; low-confidence ones prompt you to confirm.

Voice Commands

Log expenses hands-free. Say "add $45 for lunch at Chipotle" and an on-device BERT intent classifier parses the amount, merchant, and category — then silently creates the record with a 5-second undo window.

Ask Your Expenses

Type a plain-English question like "what did I spend on food in April?" and an on-device Llama model translates it to a SQL query against your local database. Tax-aware answers built in — 50% meals rule, TCJA entertainment limits, per-year IRS mileage rates.

Smart Auto-Categorization

Summa Ledger learns from your habits. It recognises 100+ common merchants out of the box and gets smarter with every expense you save — automatically suggesting the right category so you rarely have to pick one manually.

🔒 All AI models — receipt understanding, voice intent, and natural language — are downloaded to your device and run using Apple's on-device ML frameworks. Your financial data is never sent to third-party servers. The only optional cloud connection is iCloud — for backup, accountant sharing, and peer collaboration.

Core tracking is free. AI unlocks with Premium.

Download Summa Ledger free — no account, no subscription required to start. Upgrade to Premium for on-device AI, advanced reports, and accountant sharing.
