The app

A marketing operating system, not a bag of tactics

Stop adding features
to a marketing problem.

Turn an uncertain launch into a sequence of explicit questions: who the reachable buyer is, what they must believe, where behavior stops, and what evidence should change the plan.

THE GUESSING LOOP
  1. Add a feature
  2. Change the screenshots
  3. Post everywhere
  4. Read a new tactic
  5. Start over
THE SELL FIRST LOOP
  1. Map the journey
  2. Locate one break
  3. Compare causes
  4. Run a bounded test
  5. Record the decision

Native workflow

From diagnosis to documented decision

One evidence loop.
Five deliberate moves.

The workspace keeps the buyer definition, funnel map, experiment, economics, and decision together so the next action has a visible reason.

Use the free diagnostic to choose a likely demand route. Full Access opens the project workspace and complete learning library. The method asks for your observations and numbers; it does not invent market evidence or predict an outcome.

  1. 01
    DEFINE

    Name the reachable buyer

    Write the buyer, job, trigger, alternative, and reason to act in language that can be checked.

  2. 02
    MAP

    Trace the journey

    Follow behavior from first reach through storefront, activation, purchase, and retained value.

  3. 03
    EXPLAIN

    Keep causes separate

    Record competing explanations before choosing a tactic so one metric does not become a convenient story.

  4. 04
    TEST

    Bound the experiment

    Choose the audience, intervention, measure, duration, stop rule, and decision rule before the result arrives.

  5. 05
    DECIDE

    Preserve what changed

    Keep the evidence and decision together, then fix, pivot, stop, or scale with a stated rationale.

Observation → competing causes → separating test → decisionRepeat only with new evidence

Inside the app

Small enough for the phone. Serious enough for the decision.

Simple App Store access

Try the diagnosis.
Unlock the workspace.

The six-question diagnostic is free. Full Access is a single non-consumable in-app purchase made through Apple. It is not a subscription, and there is no web access code or external checkout inside the app.

  • Apple shows the current localized price before you confirm a purchase.
  • Apple handles payment. Unoptimize does not receive your card number or payment method.
  • Restore Purchases rechecks an eligible purchase without charging again.
  • Server acknowledgement links the verified entitlement to a private workspace.
IMPORTANT

SELL FIRST organizes marketing diagnosis and experimentation. It does not guarantee App Store approval, visibility, downloads, revenue, profitability, retention, or advertising performance.

Plain answers

Before you
begin.

For device, purchase, restoration, export, or deletion help, visit SELL FIRST Support.

Can I use anything without buying Full Access?

Yes. The six-question cold-start diagnostic is free and does not require an account. It returns a likely demand route, an evidence gap, and a first experiment to consider.

Is Full Access a subscription?

No. Full Access is a one-time, non-consumable Apple in-app purchase. The app displays Apple’s current localized price before purchase.

How do I restore Full Access?

Use Restore Purchases in SELL FIRST while signed in to the Apple Account associated with the original purchase. Restoration does not charge you again.

Can I export or delete my workspace?

Yes. Settings includes both account export and in-app deletion. Deletion does not refund the App Store purchase or remove Apple’s purchase history.
