## What is Hobbs?

Hobbs turns the hours you work into invoices you can send in a tap.

Run a timer or write the hours down afterwards. Hobbs rounds them, prices them at your rates, and builds a PDF invoice for each client's billing period, ready to email from your own account, AirDrop, or save. The hours you log become the invoice you send, with nothing retyped in between.

TRACK THE TIME
• Start a timer and it keeps counting with the app closed, on the Lock Screen and in the Dynamic Island, with Pause, Resume and Stop right beside the clock.
• Start one from a Home Screen or Lock Screen widget without opening the app.
• Switch tasks with one tap, or write the hours down afterwards.
• The day timeline shows how the day really went, breaks and gaps included.

PRICE IT RIGHT
• Your rate card holds what you charge for each kind of work. Override it for a client, or for a single project, and everything else follows along.
• Pick a rounding increment once: exact, 1, 6, 15 or 30 minutes, or a full hour. A task rounds once a day, from all of its time, so a pause or a switch never changes what bills.
• Add expenses to a project, one-off or recurring.

INVOICE THE PERIOD
• Each client has a billing schedule, so Hobbs knows the period. It gathers the unbilled time and expenses and lays out the PDF on your letterhead.
• Every row shows its math: hours times rate, rounded to the cent as the row is built.
• Nothing goes out unseen. You review each invoice and approve it before it can be sent, so check the figures the way you would on any bill with your name on it.
• A line per entry, per work type, or per day, client by client.
• Approving an invoice freezes it, so a new rate or a new address never rewrites one you've sent. Numbers are never reused.
• Send it from your own Mail account with the PDF attached, or share the PDF any way you like. Hobbs never sends email by itself.
• Word the email your way: greeting, note and sign-off, for all clients or for one, with the client, period and amount filled in each time.
• Follow what's issued, sent, paid, and overdue, and see at a glance who owes you what.

ESTIMATED TAX
• For a US business: how much of each payment to put aside for federal estimated tax, as a share you choose or last year's tax in four payments, with expected withholding taken off.
• The IRS due dates and the periods they cover, moved for weekends and holidays.
• See what's due next, record what you paid, and any shortfall carries to the next period.
• A reminder a week before each due date.
• Hobbs does the arithmetic and keeps the calendar. It never holds or moves money, and it doesn't give tax advice.

REMINDERS
• Invoice reminders on the day a client's invoice is due to go out, at a time you pick. They name the client and the period, never the amount.
• Timer reminders at the start and end of your workday, and after a long break, so a forgotten timer doesn't cost you an hour.

YOUR BOOKS STAY YOURS
• Clients, rates, hours, and invoices live on your iPhone and in your own private iCloud, syncing across your devices with no account to create.
• Possisoft has no server and can't see any of it.
• Export everything as one backup file of plain, readable text.

WHAT IT COSTS
Hobbs is free to download, and tracking time is free. Your first invoice is free too, whenever you send it, so you can try Hobbs on a full billing cycle of real work. After that, a one-time upgrade brings unlimited invoicing and estimated tax. It's not a subscription, nothing renews, and Family Sharing is included.

WHY "HOBBS"?
A Hobbs meter is the hour meter on an aircraft's instrument panel, the one a rented aircraft is billed from. Hobbs does the same for your work: it counts the hours you bill.

Hobbs is available on the US App Store. iPhone, iOS 26.1 or later.

## Version history (last 2 releases)

### 1.1 — 2026-10-31

New: estimated tax. For a US business with the upgrade, Hobbs works out how much of each payment to put aside for federal estimated tax, as a share you choose or last year's tax in four payments, and keeps the IRS due dates. The Paid tab shows what's due next, the year screen shows every period, and a reminder comes a week before each due date.

Also new:
• Notes on a stretch of work, with suggestions as you type, and Next stretch to start a fresh one.
• Mark as Paid is a sent invoice's main button, and the Paid tab shows what came in, by period and by month.
• Billing on the 1st and 16th? The Timesheet shows the half-month you're in.
• Split a Stretch opens blank, and the running timer follows a stretch's new end.
• An empty Timesheet offers to create a project.

### 1.0 — 2026-10-28
