The apps

Each one does a single thing, completely. Built in-house, designed for the day you don’t feel like opening it.

Daybreak: Sobriety Companion app icon

Daybreak

Sobriety Companion · Health & Fitness

LIVE

A private, gentle companion for anything you’re ready to leave behind — alcohol, cigarettes, vaping, gambling, or a habit only you can name. Count your mornings, keep your reasons close, and get yourself back. No account, no feed, no data collection.

  • Your reasons, front and center
  • “I need a minute” toolkit
  • People you can call
  • Milestones to 10 years
  • Money saved
  • Private journal
  • Carry it to a new phone
  • Begin again without shame

Day count, journal, milestones and the hard-moment screen are free, always. Daybreak Forever is one $3.99 purchase to track several things at once. No subscription, ever.

Debt Free Date: Snowball app icon

Debt Free Date

Snowball · Finance

LIVE

Turns your debts into a plan with a date on it. Enter what you owe, see exactly when you’ll be free, and watch that date move closer every time you put a little extra toward it. No account, no bank connection — nothing leaves your phone.

  • A real payoff date
  • Log what you actually pay
  • Interest vs. principal
  • Snowball vs. avalanche
  • Plan vs. what you actually paid
  • Payment streak
  • Countdown card

Free for 2 debts · Pro unlocks once — unlimited debts, avalanche, reminders. No subscription.

How we build

Three rules we don’t break.

Your data stays yours

What you log in our apps belongs to you. No ad networks, no third-party analytics SDKs, no quiet data brokerage. Ever.

No dark patterns

No manipulative streak guilt, no buried cancel buttons, no engagement traps. If an app is working, you should need it less over time.

Built for the long haul

Small, deliberate releases. Bugs fixed before features added. Software we intend to still be maintaining years from now.

About

Onyx One LLC

We’re an independent software company building iOS apps for the parts of life that don’t get a lot of good tools — the counting-days part, the paying-it-down part, the starting-over part.

Onyx is what pressure and time leave behind. That’s roughly the idea. We build slowly, ship things we’d use ourselves, and answer our own support email.

“Make the app so useful and so quiet that someone can get better and forget it’s there.”

— The brief we give ourselves

Start with day one.

Both apps are on the App Store now. Free to start, no subscriptions, nothing leaves your phone.
