Open SyncMedic and you get a short boot sequence with its own sound, composed by the founder, a working mixing engineer. It lasts a moment and then you are in the app. That is the whole ceremony.

The window has three tabs across the top: Receipts, Checkup, and Drives. Receipts is the paper trail of everything SyncMedic has done for you. Checkup is where duplicates get found and fixed. Drives is the map of what is eating your storage.

Checkup is home. It is the tab you land on and the tab you will use most, because the first thing SyncMedic wants to do for you is find the space you already paid for and give it back.

A backup job in SyncMedic is three wells: What, Where, and When. No config files, no options maze. You answer three questions and you are done.

Pick a mode. Every job runs in one of three modes, and the right one depends on what the copy is for:

The first run. Press the run button (or just plug in the drive, if that is your trigger) and watch the progress bar do its thing. Every single file that lands on the destination is read back and checked byte for byte against the original before it counts. That is why the first run of a big folder takes a little while: SyncMedic is not just copying, it is proving.

When it finishes, your first receipt appears. Click over to the Receipts tab and read it. It is one plain sentence telling you what happened, and it is the reason you will actually trust this app: not because it says "Done", but because it shows its work. More on reading receipts in the next section.

Other backup apps finish in silence and expect you to trust them. SyncMedic hands you a receipt after every single run. The Receipts tab is the full history: every backup, every fix, every run, forever.

Each receipt leads with the verdict line: one sentence, plain English, telling you the outcome. "2,314 files backed up. Everything verified." You read that, you are done. That is the whole point.

Under the verdict sit the chips: small pills that summarize the run at a glance. Byte-verified. Zero errors. Nothing deleted. Each one is a fact about the run, not a decoration.

Want the whole story? Click "Show me every file." The receipt unfolds into the complete list of every file the run touched and what happened to it. You will almost never need this, but the day you wonder "did it really copy that one session?", the answer is one click away.

If something went wrong, you get a problem card instead of a green verdict. A problem card tells you what happened in plain English, and every problem arrives with its fix attached: a button that does the repair, right there on the card. You never get an error code and a shrug. You get a sentence and a button.

Click Examine and SyncMedic scans every connected drive plus your home folder. It reads the actual content of your folders, not just the names, so it catches the folder you renamed "FINAL_final_v3" back in 2019 even though the original is called "Album Masters". Think Shazam, for your files.

While it works you will see the gauge fill up: how much has been examined and how much reclaimable space it has found so far. On a drawer full of drives this number has a habit of getting large. The first night it ran on its founder's own drives, it found 1.4 TB.

The drive chips across the top show every drive in the scan. Click a chip to exclude that drive from this Checkup, click again to bring it back. Handy when you only care about one drive today.

When the exam finishes, everything it found is triaged into three tiers:

Two numbers appear on every match, and they mean exactly what they say.

• Reclaimable is how much space you get back if you fix this match. It is the size of the duplicate copies, the storage you paid for but cannot use.
• % same DNA is how much of the two folders' actual content is identical, measured from the bytes inside the files, not the file names. 100% means every file in one is byte-identical to a file in the other.

Press Fix on a match and SyncMedic runs a four-step routine, in this order, every time:

The golden copy wears the crown. When SyncMedic picks which copy survives as the keeper, the newest and most complete copy wins. You will see a small crown on it in the match view, so you always know which folder is about to become the one true copy.

Finder tags keep you oriented outside the app. After a fix, the golden copy is tagged Yellow (Golden) and retired duplicates are tagged Gray (Retired). Open any folder in Finder and the colors tell you the story at a glance.

Fix a batch at once. Every match has a checkbox. Tick a few and the button becomes "Fix N selected". Or press Fix all safe and SyncMedic works through the entire Safe tier in one go: that is the "free 214 GB with one click" button.

While it works you get a progress bar and a Stop button. Stop is always safe to press: SyncMedic finishes the file it is on and stops cleanly, never mid-copy. And when the batch is done, you get the chime. You will come to like the chime. It means gigabytes.

Every drive SyncMedic touches gets a SafetyNet folder, right at the top level of the drive. Not buried in a library, not invisible, not encrypted into some proprietary blob. A normal folder you can see in Finder.

What rests there: duplicates retired by a Fix, and anything a Mirror backup replaced or removed. Everything arrives with its original folder structure intact, so nothing is ever a mystery pile.

Changed your mind? One click Undo. Every fix receipt has an Undo button. Click it and every folder walks back out of the SafetyNet to exactly where it lived before. No digging, no terminal, no prayer.

Or just browse it. Open the SafetyNet folder in Finder like any other folder. Drag a file out if you want it back manually. It is your drive and your files, and SyncMedic never forgets that.

When items in the SafetyNet have finished their rest period, a banner appears: so many gigabytes are ready to reclaim. Nothing has happened yet. The banner is an invitation, not an action.

Click it and SyncMedic runs the double-check audit before anything else. For every single file it is about to remove, it verifies that a surviving copy still exists: same name, same size, still on disk, right now. Not "existed last month when the fix ran". Right now, at the moment of deletion.

Anything that fails the audit gets set aside. The button says it plainly: "Set aside the unproven." If a surviving copy has since been moved, renamed, or its drive is not connected, that file does not get deleted. It stays in the SafetyNet until it can be proven safe.

Then, and only then, you confirm. Reclaim is the one and only thing in SyncMedic that ever permanently deletes a file, and it only runs after the audit passes and after you click the confirm button yourself. The app never reclaims on its own. Ever.

The Drives tab is a ranked "what's eating your drives" view. Every drive, biggest space-hogs first, so the answer to "where did my terabyte go" is the first thing on screen instead of an afternoon with a disk utility.

The part that surprises people: it works for drives that are not plugged in. The Ledger remembers every drive SyncMedic has ever met and what was on it. That drive in the drawer from 2021? Its contents are still in the list, browsable, right now. Plug it back in whenever, and the Ledger picks up where it left off.

Check for Updates lives here too. SyncMedic checks once a day on its own; this button just checks right now. License activation and that daily update check are the only two things the app ever uses the internet for. Nothing about you or your files is ever sent anywhere.

Your backups are plain files. Not an archive, not a disk image, not a proprietary format that needs the app, a login, or a subscription to open. Real folders with real files, exactly as you know them.

So if your Mac dies tonight, you plug your backup drive into any Mac, anywhere, and open it in Finder. Everything is right there with its normal names in its normal folders. No SyncMedic required. No recovery wizard. No "please reinstall the app to access your data".

That is the whole philosophy in one sentence: a backup you need special software to read is a hostage, not a backup. SyncMedic refuses to take hostages.
