About

Deftest

Features
Read full description

Deftest is a complete finance tracker for freelancers β€” jobs, invoices, payments and expenses in one fast, private app for iPhone, iPad and Mac. Your data never leaves your control. There is no account to create, no server anywhere, and nothing is collected β€” everything lives on your devices and syncs through your own iCloud. Even if you stop subscribing, your records stay visible, searchable and exportable. Your data is yours, always. TRACK THE WORK Record every job with client, volume, rate and currency. Statuses follow the real flow of freelance work: confirmed, delivered, billed, paid. Open work never hides β€” unpaid jobs and unsettled invoices always stay in view. INVOICE WITHOUT FRICTION Group delivered jobs into clean, professional PDF invoices with yearly-sequential numbering. Send them to clients directly from the app. Track due dates and see overdue invoices at a glance. KNOW YOUR NUMBERS See income by year, month, client and currency. Spot your biggest clients, follow your growth across years, and understand where the money actually comes from. Expenses sit alongside income, so profit is always in sight. WORK IN ANY CURRENCY Bill different clients in different currencies. Daily ECB reference rates give you an indicative overall picture β€” while every record keeps its true original currency. BRING YOUR HISTORY Import years of past work and expenses from CSV, with a preview before anything is committed and one-tap undo for the whole batch. Export everything, anytime, in open formats. BUILT BY A FREELANCER Deftest was built by a working translator to run his own business, and it shows: pagination never conceals open business, removed currencies stay on old records, and labels say exactly what they mean. A subscription (14-day free trial) or one-time lifetime purchase unlocks the app. If a subscription lapses, Deftest becomes read-only β€” your data stays yours.
