Axyom

A deliberate pause between impulse and purchase.

Behavioural-finance apps usually look like every other habit tracker. A streak, a leaderboard, a green dot for every day you managed not to overspend. Axyom takes a different angle: the pause itself is the product.

Most finance apps track transactions. Axyom uses AI to understand the decisions that happen before the transaction. AI is not the product. AI is the guide.

A black screen, a slow breath, and the same purchase translated into hours of the user's own work. The product isn't the budget; it's the moment of confrontation.

Designed, built and shipped solo. First version came together in three weeks; the final cut went live on the App Store fourteen weeks from the first sketch.

01

Naming the urge

The flow starts by making the user say it out loud. What are you about to buy. How much. Which category. A purchase that stays vague is easy to make — one typed into a field and priced at $1,300 is already harder.

One quiet question sits at the bottom: planned, or not. It blocks nothing. It just puts the honest answer on the screen before any money moves.

Axyom Breathe screen — a silver sphere, 'That's 74 hours of your work', and an Inhale prompt.
02

Priced in hours, not dollars

Then the screen goes black. A circle, a slow breath, and the purchase re-priced in the only currency that stings: time. "That's 74 hours of your work." Not $1,300 — 74 hours.

Nothing here can be tapped through quickly. The breath has a duration. For thirty seconds the product does exactly one thing, and it does it without a single notification.

Axyom outcome screen — $1,300 protected, $2,243 defended all time, four decisions held, paired with a chrome shield.
03

What the pause defends

If the urge passes, the screen records it plainly: $1,300 protected. Not "saved" — protected. "You kept this from becoming a way to cope."

Below it, the running total: $2,243 defended all time, four decisions held. The number grows only when the user holds. It is the closest thing Axyom has to a score, and it counts restraint, not spending.

04

The product in motion

A short view of how Axyom turns impulse into pause, reflection, and a better decision. No narration, no audio, no copy on top of the picture. The screen has to carry the argument by itself.

Plays muted on viewport. If reduced motion is on, the poster stays put — the still already tells the story.

Behavioural finance is mostly a copy problem. The math is settled; the question is whether the screen earns the user's trust.
Axyom Plan tab — a $1,000 of $5,000 safety-net target with a monthly financial snapshot beneath.
05

Planning what gets defended

The Plan tab opens on a target, not a balance — a safety net of $6,000, built $115 at a time. The bar moves only when money that would have been spent gets defended instead. Saving is framed as protection first, ambition second.

Underneath, the Financial Snapshot keeps the math plain: income, expenses, surplus, nothing decorated. A second horizon — Financial Freedom — names the long number and the age it arrives, so every weekly $115 has somewhere to be going.

Axyom Coach tab — a single priority and three suggested-question cards floating beside the iPhone.
06

Where the guide lives

In the app, the guide surfaces as a Coach tab. It doesn't open on a chat box — it opens on one priority, drawn from where the user actually stands: "Save $150/week toward your safety net." One instruction, not a feed of tips.

Three suggested questions sit below it, and a hard limit under the input: "3 questions left today." The scarcity is deliberate. A finite guide gets asked real questions; an unlimited one gets treated as noise.

Axyom Learn tab — a seven-lesson curriculum: Financial Foundations, Investing Basics, Life Decisions.
07

A curriculum, not a feed

The Learn tab is finite by design — seven lessons across three modules, in order. Financial Foundations unlocks first; Investing Basics and Life Decisions stay locked until it is done. Progress is a count — "0 of 7" — never a streak.

That sequencing is the argument. Most finance apps hand you everything at once and call it empowerment. Axyom makes you earn the next idea, so the curriculum is something you finish rather than scroll.
