SEDX, LLC
Doing business as RLTW.
SEDX, LLC builds focused mobile reference, training, and utility apps — pocket-sized field manuals, professional reference, and everyday tools. Built for people who need answers fast, offline, and without distraction.
And built the way software should be: you pay once and own it — no ads, no subscriptions, no selling your data. Premium features that competitors gate behind pricey recurring plans are a single, low-cost unlock here, and your information stays on your device whenever it possibly can.
Pay once, own it
Unlock premium features with one low-cost purchase — often a fraction of what competitors charge over a year of subscriptions.
No subscriptions, no ads
Nothing to renew, nothing to cancel, and nothing between you and the app — no banners, pop-ups, or tracking pixels.
Your data isn't the product
We don't sell or share your information. No analytics middlemen profiting off how you use our apps.
On-device by default
Your data is stored and processed right on your phone wherever it's technically possible — private by design.
No account required
Start using any app the moment you open it. No sign-up, no email, no login wall standing between you and your tools.
Works fully offline
Built to run without a connection — your reference and tools don't depend on our servers being up or your signal being strong.
How it works
Download free
Grab any app and start using it right away — no account, no email, no trial countdown.
Unlock once
Want the premium features? A single low-cost purchase unlocks them — never a subscription.
Own it, offline
It's yours for good — working fully offline, on your device, with nothing phoning home.
