Active trip screen — parsed hotel folios, gas, and tolls filling the expenses list

Review what it caught

When travel's complete, smart advisories flag anything that looks missing — add it or dismiss it with a single tap.

Review screen — progress stepper and a '2 items to review' advisory

Export screen — ZIP file, individual files, or both, with the Export Voucher button
Straight from the app

Your voucher, on autopilot.

Built for real TDY life

Everything you actually need.

Voucher autopilot

Every receipt becomes the right DTS expense line — lodging nights, taxes, airfare, rentals — assembled into a complete voucher automatically.

Smart advisories

It notices what's missing — airport mileage, a lost receipt, a Non-A letter — and asks one question to fix it. Fewer rejections, more money.

Audit past trips

Upload an old DTS voucher. TDY Slayer flags what you probably should have claimed — so you can file an amendment and get paid back.

POV mileage that does the math

Set your home address once. Real driving distance, the current GSA rate, the right expense line — one tap.

Mass import

Dump in a whole camera roll at the end of a trip. Pages that belong together find each other — no sorting by hand.

Per Diem Lookup

Current lodging and M&IE rates for any base or city, CONUS or OCONUS — without digging through the DTMO site.

Already filed?

We can still find money you left behind.

Upload old DTS vouchers or trip records. TDY Slayer reviews what you claimed and surfaces likely missed expenses — airport mileage, parking, per-diem adjustments, Non-A situations. People recover real money from trips they thought were done.

Questions

Frequently asked questions

Is this an official DoD or DTS app?

No. TDY Slayer is built by Southwind Digital LLC, a small veteran-owned company. It's a private tool that makes the official DTS process faster and more accurate — you still file your voucher in DTS.

How well does it actually read receipts?

Incredibly well. If you can read it, the app can read it — including the messy multi-page hotel folios that cause most voucher problems. It's not perfect, but it tells you when it isn't confident, and you can edit anything.

Does it handle foreign currency and OCONUS trips?

Yes. Foreign receipts convert to USD using the official Treasury rates for that date, and per diem works for overseas and remote locations — including International Date Line crossings.

What about Non-A letters and on-base vs off-base?

It spots when you're on base or need a Non-A letter and asks the right questions. Once you confirm, it uses the correct rate for those nights.

What does it cost?

The app is free to download, and everything is unlocked for your first week. After that, capture, receipt reading, per diem, and DTS-formatted export stay free. TDY Slayer Pro — smart advisories, the full voucher view, and past-voucher audits — is $4.99/month or $39.99/year with a 7-day free trial.

Is my data private?

Your trips and receipts live on your device. Receipt images are sent securely to our AI providers only to be read, then deleted — never stored elsewhere, never used for training. Sign in with Apple means we don't even need your name or email. Details in the privacy policy.

What devices does it run on?

iPhone, running iOS 18 or later.
