WalkthruComing soon

Record once · iOS 26 · On device

Record it once.
Walkthru finds the steps.

It cuts your iPhone screen recording where the screen actually changed, then hands you a guide to annotate, redact and export. Nothing is uploaded, because there is nowhere to upload it to.

What you get

Refund a customer’s order · 5 steps

  1. Step 1 of the finished guide: an orders list, with an ink marker on the order that needs attention.

    1Open the order in Needs attention

  2. Step 2: the order’s details, with the customer’s email, phone and card covered by solid black redactions, and a marker on the Refund button.

    2Tap Refund this order

  3. Step 3: the refund amount being typed on a keypad, labelled “type amount”.

    3Type the amount to refund

  4. Step 4: a confirmation dialog asking to refund $48.00, with a marker on Refund.

    4Confirm the refund

  5. Step 5: the order marked refunded.

    5The money is on its way back

Five steps found in a 28-second screen recording — markers, redactions and crops baked in. Walkthru finds the moments and what kind of action each one is; the captions are the author’s own words.

Why this exists

Every other tool asks you to plug in a Mac.

Scribe, Tango, iorad and Guidde all document desktop flows by watching your clicks — a thing iOS does not let any app do. Their official answer for mobile is to mirror your phone to a Mac, or to upload the recording to their website. Walkthru takes the other route: it reads the recording itself, on the phone that made it.

How it works

Four stages, in order.

1

Record the flow once

Use Walkthru’s own recorder, or import a recording you already made with Control Center. Nothing is uploaded either way.

Path A

Record in Walkthru

One tap starts a system broadcast. iOS shows the recording indicator the whole time and the file lands straight in the app — never in your Photos.

Path B

Import what you already have

Recorded with Control Center yesterday? Pick it from Photos, or drop the file onto the library. Full quality, no re-encode.

Playing here: the recording the guide at the top of the page came from — 28 seconds of screen time, sped up so you don’t have to wait.

Walkthru finds the steps

It reads the recording frame by frame and cuts it where the screen actually changed — then labels each cut: a new screen, a step back, a scroll, a swipe, typing, a dialog, a toggle.

Five cuts from a 28-second recording, with the moment each one happened. What Walkthru held onto — a keyboard still animating, a screen still settling — never became a step of its own.

Mark up what matters

Tap the frame to place a marker. Drag a box over anything that shouldn’t ship. Walkthru offers redactions for the addresses, card numbers and keys it spots — offered, never applied on its own.

It reads the screenshot on your phone and says what it found — here, an email address and two phone numbers.
Step 2: the order’s details, with the customer’s email, phone and card covered by solid black redactions, and a marker on the Refund button.
One tap, and they are gone from the file. Filled in solid, not blurred — the pixels underneath are destroyed in the export.
  • Tap the frame to place a marker — tap, double-tap, long-press or swipe — or add a text label and draw on the picture.
  • A redaction is filled in solid, not blurred. Blur and pixelation are recoverable when the font is known — and on a screenshot it always is.
  • Walkthru reads each frame on the device and offers to cover emails, phone numbers, postal addresses, card numbers, IBANs, SSNs, routing numbers, wallet addresses and likely secrets.
  • Accept a redaction on every step at once when the same detail repeats down the flow.

Offered, never applied on its own. Walkthru does not decide what is private in your screenshot — it decides what is worth asking about.

Send it where it lives

A PDF for the SOP folder, Markdown for the docs site, images for Notion or a support reply — or the whole guide as a video. Markers and redactions are baked into the file.

PDF

One step per page, compact, or a checklist. Letter or A4.

Markdown

A zipped bundle with relative image references.

Images

Annotated PNGs to Photos or Files.

Video

An MP4 of the guide — markers landing in time, redacted steps held still, optional narration.

The same guide, exported as video — markers landing, redactions in place. This one is the real file, playing.

The app

All of it happens here.

Steps down the left, tools down the right, the picture in the middle. Screenshots from an iPhone — not mock-ups.

Walkthru's step editor: a strip of numbered step thumbnails on the left, annotation tools on the right, and the first step's screenshot in the middle.
Every step in the guide, in order. Tap one to work on it.

Seven marker colours, because a marker has to stand out on whatever screen you recorded.

Privacy

There is nowhere to send it.

A screen recording contains whatever you had on screen. Walkthru’s answer to that is structural rather than promissory: no accounts, no servers, no per-frame upload, no cloud model. Detection, text reading, redaction and export all run on your device.

You do not have to take this on trust. Turn on Airplane Mode and use the app — every feature behaves identically, because none of them ever needed the network.

Data collected
None. The App Store privacy label reads “Data Not Collected”.
Account
There isn’t one. Nothing to sign up for, nothing to sign in to.
Processing
On device. Step detection, on-screen text reading and PII detection all run locally.
Redaction
Opaque fill, rendered before the crop and baked into the export. The pixels underneath are gone in the exported file.
Analytics
None. No SDKs, no crash reporters, no identifiers.

Documenting one flow this week? $2.99 buys a seven-day pass instead. It does not renew.

Questions

What people ask first.

Do I need a Mac?

No. Walkthru records, detects the steps, annotates and exports entirely on the iPhone or iPad. Every comparable tool — Scribe, Tango, iorad, Guidde — documents mobile flows by mirroring the phone to a Mac or by uploading the recording to a website. Walkthru is the one that stays on the device.

Where does my recording go?

Nowhere. Walkthru has no account system and no server, so there is no address it could send a recording to. Step detection, text reading, redaction and export all run on the device. You can check this: turn on Airplane Mode and the app works exactly the same.

Can I import screenshots instead of a recording?

No. Walkthru takes a screen recording — an MP4 or MOV — and finds the steps inside it. It cannot open a folder of screenshots. If you already have separate screenshots, a screenshot annotator is the better tool.

Does Walkthru write the step captions for me?

No, and that is deliberate. Walkthru decides where the steps are and what kind of action each one is, because both are measurable from the pixels. It does not guess at the wording. A plausible but wrong caption costs more to notice and correct than an empty one costs to write, so imported steps arrive untitled.

What does Walkthru cost?

The download is free, with every format and no cap on steps or guides. The free tier watermarks exports and allows three shares a day. Pro removes both: $9.99 once, or $2.99 for a seven-day pass.

Does the seven-day pass renew automatically?

No. It is a non-renewing purchase, so it simply ends after seven days and never charges you again. Buy another when you need one; they stack.

Can Walkthru record other apps?

Yes. It captures the whole device screen, other apps and the Home Screen included, using the system broadcast picker — so iOS shows the recording indicator the entire time. You can also record with Control Center first and import the file afterwards.

What can I export?

A PDF in one of three layouts, a Markdown bundle with relative image references, a sequence of annotated PNGs, or an MP4 video of the guide with the markers landing in time. Markers, crops and redactions are baked into every file, not stored as removable overlays.

Does Walkthru need an internet connection?

No. There is no account to sign in to and no server to reach, so nothing in the app uses the network. Step detection, text reading, redaction and export all work with Airplane Mode on. The only network activity is Apple processing a purchase.

Is there a Mac, Android or web version?

No. Walkthru is an iOS app for iPhone and iPad, and there is no web version because there is no server — processing happens on the device. For desktop flows, the browser-based tools cover that side; on the Mac, StepGrab does local, on-device guides. Walkthru is the one that does it on the phone.

Does it work on iPad?

Yes. Walkthru is a universal app for iPhone and iPad. On a wide window the guide library sits in a sidebar, and the editor keeps its tools in a rail beside the picture. It requires iOS 26 or iPadOS 26.
