## What is Addendum.?

Rounds today. ERAS tomorrow.

You will write your residency application out of things you have already seen. Addendum is where you put them down while they are fresh: a deidentified line about the case, the feedback, the procedure, the moment you would otherwise lose by Friday. A year later those notes are the raw material for your MyERAS experiences, your personal statement and your interview answers, and you retype none of it.

Private, encrypted on your device, offline by default. No account, no analytics.

ON THE WARDS
• Capture first. The app opens to a box. Type it, or dictate it. Speech is transcribed on your phone and the audio never leaves it.
• Deidentified by construction. Addendum never asks for a patient's name, date of birth, record number, location or photo. Ages are broad bands, and no date of service is asked for. A check runs as you write, and again before anything leaves the app.
• Mark what mattered. One tap flags an entry standout, so at year's end you review a shortlist.
• Tips, Tricks, & Tests. Bank what you get asked on rounds, and what you wish someone had told you about the rotation. Spaced review brings it back before the shelf.
• Gap Check. Which interview themes still have no entry behind them.

WHEN YOU APPLY
• ERAS composer. The MyERAS structured fields, with live character budgets, a blocking deidentification scan, and prose ready to paste.
• Programs and evidence. Keep your own program list and link entries to it. Open a program and see what substantiates it.
• Letters. Track each writer from "to ask" to "uploaded", and export a packet for each writer with the patient details stripped.
• Signals. A budget, not a list, because a signal spent on one program cannot be spent on another. It records why you spent each one.
• Rank worksheet. Weighted fit beside your gut read, with the divergence surfaced for a written reason.
• Interview season. Your real moments mapped onto the classic "tell me about a time" prompts as STAR stories, plus invitations, debriefs and thank you notes.
• If your specialty uses ResidencyCAS, the SF Match or the urology match, the app says so.

WHAT IT WILL NOT DO
• Write for you. There is no model in the app and no generated prose. The words are yours.
• Invent a cycle fact. Character limits, signal counts and deadlines ship empty. You verify each against the source named on screen, and unverified means the app says so.
• Tell you your odds. Fit, never probability.

PRIVATE BY DESIGN
• Offline. The journal makes no network requests. Its Content Security Policy blocks them, and a Settings screen shows you that policy and the check passing on your own copy.
• AES encryption in GCM mode, with a key derived from your passphrase (PBKDF2, 600,000 iterations). Optional Face ID or Touch ID unlock via the Secure Enclave.
• Kept out of device and iCloud backups: a restored phone will not restore your journal. Export an encrypted backup, or turn on sync, before you switch.
• Optional iCloud sync, off by default, carries only the encrypted vault. Apple cannot read it. The one purchase goes through the App Store, which sees nothing you wrote.
• Save the recovery key shown at setup. It is how you get back in if you forget your passphrase.
• Optional reminders on this device, off by default. Notifications carry no journal content.

Your journal is free forever: writing, searching, printing, exporting, backing it up, Tips, Tricks, & Tests and Gap Check. No subscription, no tiers. When application season arrives, the Apply tab (ERAS composer, Letters, Interview, Season) unlocks with one purchase. Already using it? It stays yours, free.

Addendum is a personal reflective journal. It is not an electronic health record, not clinical decision support, and not a substitute for any patient encounter log your school requires. You are responsible for keeping every entry deidentified and for following your institution's policies.

## Frequently asked questions about Addendum.

### What is Addendum?

Addendum is a private, offline journal designed for third- and fourth-year medical students. It helps you capture and organize clinical moments from your rotations to use in your residency applications, personal statements, and interviews.

### How does Addendum help with ERAS applications?

Addendum allows you to draft ERAS experiences directly from your captured moments. It provides live character budgets and prompts to help you strengthen your descriptions, mapping them to official experience types.

### Is Addendum secure and private?

Yes, Addendum is built with privacy as a core feature. All data is encrypted on your device using AES-GCM and is excluded from device backups. It operates offline by default and does not collect patient identifiers.

### Can I use Addendum offline?

Absolutely. Addendum is designed to work offline by default, meaning it functions even in Airplane Mode. Optional iCloud sync is available but is off by default and only syncs your encrypted journal across your Apple devices.

### How does Addendum help with interview preparation?

You can map your captured real moments onto classic interview prompts as STAR stories within Addendum. The app allows you to drill these stories one at a time and manage your interview season logistics.

### What kind of content can I save in Addendum?

You can jot down de-identified clinical moments, 'pearls' of teaching you receive, and reflections on your experiences. The app is designed for quick capture, allowing you to dictate notes if your hands are full.

### Does Addendum have ads?

No, Addendum does not contain advertisements. It is a completely ad-free application, allowing for an uninterrupted journaling and preparation experience.

### What devices does Addendum support?

Addendum is available for iPhone and iPad, making it accessible on your preferred Apple mobile devices.

## Version history (last 5 releases)

### 3.9.0 — 2026-09-29

• Change your passphrase without typing the old one. Where your device can confirm it's you (Face ID, Touch ID or your Mac login), it steps in instead.
• Extra protection to match: if the passphrase is changed without that proof, the few settings that could lock you out stay on hold until you confirm with Face ID, Touch ID or your recovery key.
• Updated 2027-cycle guidance in Apply → Guidance for CVs, letters, signaling and DO applicants.
• Bug reports you choose to send reach us again.
• The app now names both things that can ever leave your device: optional iCloud sync, and a bug report you write and send.
• Fixes: two open windows can no longer overwrite each other, a refused save now says what actually happened, printing works on the Mac, and the de-identification check also reads field names and numbers.

### 3.8.0 — 2026-08-23

The whole app is a chart now.

The top tab bar is gone. Navigation moved to the left edge, where your sections sit as colour-coded divider tabs — tap one and that divider becomes the page you are reading.

Every screen opens as a printed form, with its own code and date over a rule, and closes with a footer. A record you amend more than an hour after filing it gets stamped ADDENDUM in red, so your own edits are visible the way a real chart shows them. Stats rules itself as a ledger flowsheet, and Year on the Wards opens as a fold-out.

New in Settings: Stock. Eleven colour sets — Manila plus ten dyed ones — that re-colour the dividers and the paper together. Every one is contrast-checked in both light and dark before it ships.

Fixes: the navigation no longer drifts off-screen on iPhone, headings no longer clip at the edge of the screen, and iPad no longer describes itself as a Mac.

Your journal is unchanged and opens exactly as before.

### 3.6.9 — 2026-08-11

A quiet release. 3.6.6 brought the application season; this one hardens it. Every fix below came from auditing that release's own fixes, three rounds deep, because a correction is exactly where a new mistake likes to hide.

FIXED
• Grandfathering is safe now. If you used the application tools before they became paid, an interrupted first unlock could seal that access away permanently. It cannot any more, and the check now reads a value that never changes once your journal is created.
• iCloud sync tells you when it stops. A journal that outgrows what iCloud can hold in a single record used to stop syncing silently while Settings still said On, which you would discover while restoring a lost phone. Addendum now names that state plainly and points you at the encrypted backup, which has no such ceiling.
• Send feedback no longer blocks itself. The form asks for a reply address, then flagged that same address as an identifier and refused to send. It also keeps what you typed if anything goes wrong on the way out, instead of losing the paragraph you just wrote.
• Dictation is steadier. It cannot start twice, and cancelling while the permission prompts are open now closes the microphone properly rather than opening it a moment later.
• Nothing paints over a locked journal. A few late arriving messages, and the feedback form itself, could appear on top of the lock screen. They stay closed.

Your entries, your passphrase and your backups are untouched by all of it.

### 3.6.6 — 2026-08-11

Addendum's premise is that a year of clerkship notes should become next year's residency application without retyping them. v2.5.1 captured the notes; this release builds the other half. Nothing since 2.5.1 was ever released, so all of it is new to you.

NEW IN 3.6.5
• Three tabs instead of nine: Capture, Browse Journal and Apply, with Settings and Send feedback as icons in the corner. Nothing was taken away; the other screens live inside these three now.
• Apply is a checklist you walk, not a cabinet you search. One ordered path from your first story to your rank list, a step at a time, and it picks up where you stopped.
• Browse Journal groups your entries into rotation blocks, taken from the rotations you close out. Search still cuts across every block.
• Quiet encouragement, all of it optional. Checklist progress, tips due, coverage rings, a look back at your week and at each rotation you close, your own records, a weekly rhythm you set yourself, and one of your own entries from a year ago today. Nothing counts a streak you can break, nothing turns red, each has its own switch in Settings, and reminders stay off until you turn them on.
• Apply is a one time unlock. Your journal stays free forever: writing, searching, printing, exporting and backing up, along with Tips, Tricks, & Tests and Gap Check. Already using the application tools? They stay yours, free and permanently.

THE APPLICATION SEASON (built since 2.5.1, all new to you)
• ERAS composer: the MyERAS structured fields, live character budgets, a blocking deidentification scan, and prose ready to paste in MyERAS field order.
• Programs and evidence: keep your own program list, link entries to it, and open a program to see what substantiates it. Each experience and letter writer gets the same, including where you have logged nothing yet.
• Letters: writers are real records tracked from "to ask" to "uploaded", with an aging nudge.
• Signals: a budget, not a list, capturing why each decision was made when you made it.
• Rank worksheet: weighted fit beside your gut read, with the divergence flagged for a written reason.
• Season roadmap, dashboard and an application timeline, built from your own verified cycle dates.
• Import interview invitations from a calendar (.ics) file, read on your device.
• Export your procedure log as CSV in the shape schools ask for: counts only, no dates.
• If your specialty applies through ResidencyCAS, the SF Match or the urology match, Addendum names that service instead of assuming ERAS.
• Faster logging: a procedure in three taps, repeated in one. COMAT as a full exam type beside the shelf. Photo to text that runs on your device and never stores the image. A stronger Argon2id option.

CLAIMS THE APP HAD NOT EARNED
• Every number that changes with the cycle now comes from your own verified cycle settings, or the app says it does not know.
• Over a character limit now tells you whose limit it is and where the number came from. Writing is never blocked and nothing is ever truncated.

ALSO
• A new visual system, verified for contrast in both themes. Pearls is now Tips, Tricks, & Tests. Coverage is now Gap Check. Same screens, same entries.
• Backups identify themselves and their checksums are verified before an import overwrites anything.
• Privacy you can verify: confirm on your own copy, from Settings, that the app makes no network requests of its own.
• Audited end to end before release; 68 findings fixed, three of them serious: a patient name could ride out of a letter packet, an all caps chart header scanned clean, and one editor could discard another's unsaved draft. Also fixed: goal packs that never accrued, an export that skipped its identifier scan, and interview dates that could read a day early.
• If you sync across devices, update all of them. An out of date device will say the journal was made by a newer version and ask you to update first. Nothing is deleted.

### 2.5.1 — 2026-07-21

Quick unlock for devices without Face ID or Touch ID (like many Macs): opt in once and unlock with your Mac login password, Apple Watch, or device passcode instead of retyping your passphrase. Strictly optional — Addendum offers it once, it lives in Settings → Security, and on devices with Face ID / Touch ID nothing changes. Your passphrase always still works.
