do over

Type it once.
Get it every time.

Give do over a list and a template, and it writes the template out once per item, live as you type. Five metrics become a SELECT statement. Thirty labels become a Swift enum. Twelve months become a numbered list. It's mail merge for text.

For iPhone, iPad, and Mac. Requires iOS 26, iPadOS 26, or macOS 26 or later. No ads, no account.

Five metrics turned into SQL sums on iPhone, and thirty content warnings turned into a Swift enum on iPad

Inspiration

Macro arrays, minus the SAS.

For over a decade, I wrote SAS code built on a pair of macros, %do_over() and %array(), from Ted Clay's Tight Looping with Macro Arrays. When my job moved me off SAS, I still wanted them for bash and SQL. A shell script worked; this app is the version I wanted to carry around.

do over is the oldest app I have on the App Store, and this release is a ground-up modernization: a synced library of lists and templates, a real Mac app, Undo everywhere, and a new Liquid Glass icon. Here's everything that's new.

Template

One token.
Every item.

Write the template once, with a token where each item goes. The token is ? until you pick another, so the template never fights the text you're writing.

?

The item

Each item, exactly as typed.

?i · ?n

Index and total

The item's position, counting from 1, and how many items there are. \i+n or \i-n shifts every index.

\U \u \L

Case

UPPERCASE, Capitalized, and lowercase, plus \c camelCase, \s snake_case, and \k kebab-case.

\?

The literal token

Escape the token when you need the character itself in the output.

Numbered list

Template

?i. \u?

Results

1. Apple
2. Banana Cream
3. Coconut & Almond

SQL sums

Template · Prefix SELECT

sum(?) as var_?i

Results

SELECT
sum(spend) as var_1, sum(impressions) as var_2, sum(clicks) as var_3, …

Swift enum

Template · Prefix and suffix wrap it

    case \c? = "?"

Results

enum TriggerType: String {
    case yourTriggers = "Your Triggers"
    case bodilyHarm = "Bodily Harm"
    …
}
The \help trigger listing the template syntax on iPhone, and the Case Transformations template on iPad

Join, prefix, suffix. Join the copies with a new line, a comma, or anything else. A prefix and suffix wrap the whole result once, and can use the total count, ?n. The result without them is right there too.

Forgot the syntax? Type \help (with the trailing space) as the template, and it becomes a cheat sheet: every switch, demonstrated on your own items in the results.

Copy, share, or go again. Copy or share the results, or send them back to the item list, split the way they were joined, and run them through a second template.

Items

Bring a list.
Or don't.

Split your items on any delimiter: a comma, a tab, a pipe, a new line, or  >  if that's how your list came. Then sort, shuffle, or remove duplicates without leaving the keyboard.

The bar above the keyboard with Clear, Sort, Shuffle, and Remove Duplicates, on iPhone and iPad

\1-100

Number ranges

Type \m-n and the range fills in, joined with your delimiter. Negative numbers work, up to 10,000 values at a time.

\days

Built-in lists

Days and months, full or three letters (\days3, \months3), and the 50 U.S. states, by name or postal code (\states, \states2). \help lists them all.

A–Z

Sort and shuffle

Sort in natural order, so item 2 comes before item 10; sort again to reverse. Shuffle, or remove duplicates and keep the first of each.

⌘Z

Undo

Sort, Shuffle, Remove Duplicates, Clear, inserting a switch, opening a saved list: the buttons and menus can be undone and redone like your typing, on iPhone and iPad as well as the Mac.

A bar above the keyboard. On iPhone and iPad, the bar changes with the field: Sort, Shuffle, and Remove Duplicates for the item list; every case switch, index, and count for the template; Comma, Tab, Pipe, and New Line for delimiters and joiners. Arrows step between fields.

Room for the details. The delimiter, token, joiner, prefix, and suffix fold away under each section until you need them.

Examples

Try these.

Each one, typed into do over, gives exactly the results shown.

Simple index

Number each item.

Items
apple banana coconut
Delimiter
a space
Template
?i. ?
Token
?
Join with
a space

Results

1. apple 2. banana 3. coconut

Changing case

Three casings of the same item.

Items
APPLE Banana coconut
Delimiter
a space
Template
Uppercase: \U?, Capitalized: \u?, Lowercase: \L?
Token
?
Join with
a semicolon and a space

Results

Uppercase: APPLE, Capitalized: Apple, Lowercase: apple; Uppercase: BANANA, Capitalized: Banana, Lowercase: banana; Uppercase: COCONUT, Capitalized: Coconut, Lowercase: coconut

Code-friendly names

camelCase, snake_case, and kebab-case from plain labels.

Items
Your Triggers|Bodily Harm|Drugs/Alcohol
Delimiter
|
Template
camel \c? snake \s? kebab \k?
Token
?
Join with
a new line

Results

camel yourTriggers snake your_triggers kebab your-triggers
camel bodilyHarm snake bodily_harm kebab bodily-harm
camel drugsAlcohol snake drugs_alcohol kebab drugs-alcohol

Escaping the token

Need the token itself in the output? Put \ in front of it. Here the token is _, so \_ is a literal underscore.

Items
APPLE Banana coconut
Delimiter
a space
Template
SUM(_) AS var\__i
Token
_
Join with
a comma and a space

Results

SUM(APPLE) AS var_1, SUM(Banana) AS var_2, SUM(coconut) AS var_3

SQL conditions

Any text can be the token, like [x].

Items
apple|coconut|banana
Delimiter
|
Template
([x] IS NOT NULL)
Token
[x]
Join with
“ and ” (spaces around it)

Results

(apple IS NOT NULL) and (coconut IS NOT NULL) and (banana IS NOT NULL)

Start counting at zero

\i-1 shifts every index down by one.

Items
spend|impressions|clicks|conversions|revenue
Delimiter
|
Template
\i-1 SUM(?) AS metric_?i
Token
?
Join with
a comma and a space

Results

SUM(spend) AS metric_0, SUM(impressions) AS metric_1, SUM(clicks) AS metric_2, SUM(conversions) AS metric_3, SUM(revenue) AS metric_4

Counting

?n is the total, in the template or the prefix.

Items
north,south,east,west
Delimiter
,
Template
?i of ?n: ?
Token
?
Join with
a new line
Prefix
Directions (?n) and a new line

Results

Directions (4)
1 of 4: north
2 of 4: south
3 of 4: east
4 of 4: west

Library

Save the list.
Save the template.
Mix them later.

Lists and templates are saved separately, so last month's metrics can meet next month's query. Save either one, or both at once, each with its own name. The library syncs through your iCloud account, so what you save on the phone is on the Mac.

Saved Templates on iPhone, and editing the Metrics list on iPad

Edit in place. Rename a saved list or template, change its items, delimiter, token, joiner, prefix, or suffix, and see a live preview before you save: the items as they'll split, or the template run on the first items in your list (or sample items, if the list is empty).

Starts stocked. Six lists (Days of the Week, Months, Metrics, Fruit, Emojis, and Content Warnings) and five templates (Numbered List, Item Number, SQL Sums, Case Transformations, and Swift Enum).

Delete freely. Remove any default you don't want. Restore Defaults brings back the ones you removed, and never removes or replaces anything of yours.

Mac

A Mac app that acts like one.

Labeled fields across the full width of the window, menus for everything, keyboard shortcuts, and windows that each keep their own work.

do over on the Mac in dark mode: the Emojis list run through the Swift Enum template, with Copy and Share in the toolbar

Menus

Open and save lists and templates from the File menu. An Items menu to sort, shuffle, remove duplicates, and send results back. Template › Insert for every switch. View toggles for each set of options.

Keyboard

⌘S saves the list and template together. ⇧⌘C copies the results. Copy and Share sit in the toolbar.

One window per job

Every window has its own list and template, and each comes back as you left it after a relaunch. New windows pick up where you last left off, or start empty if you prefer a clean slate.

Shortcuts

Chain it.

Two actions for the Shortcuts app and Siri, both running without opening do over. Feed one action's output into the next to chain permutations together.

Permutate Text

Items, delimiter, template, token, joiner, prefix, and suffix in; the results out. The same engine as the app. (The \ triggers such as \days and \help are app-only.)

Resolve Range

A range like -2-2 and a delimiter in, -2, -1, 0, 1, 2 out.

Step 1

Build a pattern that still has a token for step 2.

Items
a b
Delimiter
a space
Template
? != _
Token
?
Join with
“ and ” (spaces around it)

Results

a != _ and b != _

Step 2

Step 1's results become the template.

Items
x y
Delimiter
a space
Template
step 1's results
Token
_
Join with
“ or ” (spaces around it)

Results

a != x and b != x or a != y and b != y

Get the shortcut. This shortcut runs those two steps.

Just ask. "Permutate text in do over" or "Resolve range in do over" starts either one with Siri.

What's New

The oldest app,
rebuilt for 2026.

do over first shipped in 2022. This release keeps the template syntax you know and rebuilds nearly everything around it.

Settings on iPhone, and every option expanded on iPad

Library

Saved lists and templates, synced through iCloud, editable in place, with restorable defaults.

Mac

Full-width labeled fields, File, Items, and Template menus, toolbar Copy and Share, and independent windows that restore.

Undo

Sort, Shuffle, Clear, Open List, and the rest of the buttons and menus are steps you can undo and redo, not just your typing.

Picks up where you left off

Your last list and template come back at launch. The old example picker and demo became the default library entries.

Sturdier engine

Templates expand in a single pass, so an item that contains the token is never expanded twice. An empty delimiter keeps the list whole instead of splitting every character. Huge index offsets and ranges no longer freeze or crash, and the Shortcuts action now honors its prefix and suffix.

Modern foundations

Swift 6, iOS 26 and macOS 26, a layered Liquid Glass icon, and a Color scheme setting that follows the system again.

Gone. The App Clip, the Paste button, the example picker, and the demo.

The details. See the release notes for the full list, and the examples for more templates to try.

Pricing

Buy it once.
Share it with family.

do over is a one-time purchase on the App Store. No subscription and nothing to renew; pay once and it's yours.

Price. The price is shown on the App Store and varies by country and region. One purchase covers iPhone, iPad, and Mac under the same Apple Account.

Family Sharing. With Family Sharing turned on, up to five other people in your family can download do over at no extra cost.

Privacy

Data Collection

do over does not collect any data. There are no accounts, analytics, ads, or tracking. Nothing you type leaves your device unless you copy or share it yourself.

iCloud

Saved lists and templates are stored in your own iCloud account so they sync between your devices. I can't see them.

Data Sharing

Given the above points, do over cannot share data. do over is a SwiftUI app and makes use of Apple's developer libraries exclusively; no third-party libraries. These Apple libraries do not, to the best of my knowledge, collect data.

Data Retention

Since do over does not collect data, do over cannot retain data. Saved lists and templates are yours to delete from the library at any time, which removes them from iCloud as well.

Support

There's not much that can go wrong with do over. That said, if after restarting your device and reproducing the issue you think you've found a bug, please reach out; I don't like bugs either. See the release notes for what's changed, and the examples for ideas.

Terms

Feel free to use do over at your leisure for whatever purpose you have in mind. Here's Apple's standard EULA.

Refunds

All do over purchases are final. I cannot issue refunds for charges to your Apple Account, but you can ask Apple to do so.

Your text

Anything you make with do over is yours.
