## What is däpter?

däpter is the notes app that does the math for you.

Just start typing. Any line that looks like a calculation lights up and shows its answer in the margin — instantly, as you type. The rest stays plain text. It's a notebook and a calculator in one, and it speaks plain English.

WRITE MATH LIKE A SENTENCE
• 2 + 2, (120 × 1.2) / 4 — answers appear the moment you type them
• 20% of 300, 200 - 10% — percentages, markups and discounts the way you'd say them
• 100 usd in eur, $50 + 20% — live currency conversion with proper money formatting
• 10 km + 5 m in miles, 6 m / 2 s → 3 m/s — real units that convert and combine correctly
• today + 21 days, 3 days + 12 hours — plan, count down and schedule inside a note

MAKE A NOTE INTO A TINY SPREADSHEET
• Name values and reuse them: rate = 45, then rate × hours on a later line
• Running totals: sum a block for budgets, receipts and quick tallies
• Built-in functions and constants: round, sqrt, pi, and more

PROSE AND NUMBERS, TOGETHER
Write like you normally would. Only the calculation lines light up, syntax-highlighted live so a note reads clearly at a glance. One broken line never breaks the rest of your note.

PRIVATE BY DESIGN
Everything is computed on your device, with no servers and no account. Your notes and numbers never leave your phone. All the calculating, unit conversion and currency math is free, forever.

BUILT FOR EVERY DEVICE
A clean, native, Apple-Notes-style experience on iPhone and iPad, with light and dark themes. Available in English, Russian and Kazakh.

DÄPTER PLUS
Upgrade to Plus for unlimited notebooks and to support independent, local-first software. Available as a monthly, yearly or one-time lifetime purchase.

Perfect for budgets, invoices, travel planning, freelance quotes, recipes, quick estimates — anywhere you'd otherwise reach for a calculator and then forget what the numbers were for.

## Version history (last 5 releases)

### 1.5.0 — 2026-08-11

iCloud Sync is here — your notes, in step across your devices.

Turn it on in Settings and däpter syncs through your own private iCloud:
your Apple account, your storage, never our servers. It's off by default,
and if two devices edit the same note at once, däpter keeps both rather
than picking a winner.

Part of däpter Plus, which is now a one-time unlock at a much lower price.

Plus a quieter Settings screen — the sync row only speaks up when
something needs you.

### 1.4.0 — 2026-07-28

New in this update:
• Home-screen widget — keep your three most recent notes one tap away, right on your iOS home screen. Tap any of them to jump straight into that note.
• "New Note" quick action — long-press the däpter icon to start a fresh note instantly, without opening the app first.
• Smoother launches — the app now reopens exactly where you left off, with fixes to how it opens from the widget and the home screen.
 
As always, your notes do the math as you type. Currencies, units, dates, percentages and running totals, all in plain English (and Russian and Kazakh). Everything stays on your device: no account, no servers, no internet required.

Thanks for using däpter!

### 1.2.0 — 2026-07-18

däpter now speaks volume — gallons, cups, tbsp, and any length³. Type your tank, get your liters.

### 1.1.1 — 2026-07-15

Fixed cursor alignment in the note editor on iOS

Thanks for the feedback, keep it coming!

### 1.1.0 — 2026-07-14

This update makes the calculating note editor smarter and faster.

- Label your numbers. Write the way you think — 5 apples or 627263 kg of apples now calculate just fine. Words after a number are treated as labels and quietly ignored in the math.
- Smooth editing in long notes. We rebuilt how large notes render, so scrolling and typing stay fast no matter how much you've written.
- Snappier results. Calculations now update more efficiently as you type, only recomputing what actually changed.
- Cleaner layout. The results gutter now appears only on lines that have something to show, keeping plain text distraction-free.
- Keyboard fix. Fixed cursor positioning so it no longer hides behind the keyboard while you edit.
