## What is Deepcalc?

Deepcalc is a spreadsheet for your iPhone and iPad. It opens Excel and csv files as they are, and keeps every change you make.

- Open, edit and save .xlsx and .csv files from Files, Mail or any app. The original is kept before the first save.
- It sees your tables: headers, inputs and results are outlined as you type, and one tap makes a block a real table.
- It says what comes next: select a column of numbers beside its months and the next three appear, ready to accept.
- Every change kept: history for every cell, branches to try an idea, and a way back to any earlier version.
- Comments on a cell, a range, a column or a row, with replies and Resolve. They stay in the .xlsx, so Excel reads them too.
- The panel: Cell, Check, What If, Insights and Changes. A column on iPad and on iPhone Duo, a sheet on iPhone.
- A formula key row above the keyboard: =, brackets, operators and the functions you reach for.
- Made for iPhone Duo: the same sheet closed, open or folded like a book.

No account and no sign-in. Your files stay on your device.

## Version history (last 2 releases)

### 1.1 — 2026-11-04

Opening a large spreadsheet no longer freezes the app. It opens in the background, with a Cancel button, and faster than before.

New: anonymous usage counts, such as how many spreadsheets are opened and how long a file takes to open. Never a file’s name or anything in it. Turn them off with “Share Usage Data” in Settings.

### 1.0 — 2026-10-27

No release notes.
