Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

A record of how you decide. Most decisions feel resolved the moment you make them. Reckon keeps the prediction, the confidence, and the reasoning. Over time you can see how your judgment holds up. CALIBRATION, FINALLY SOMETHING YOU CAN SEE Every decision in Reckon starts with what you think will happen and how sure you are. Over months, that turns into a record you can read: confidence over time, predicted vs. observed, the difference between the calls you make well and the ones you only think you do. INSIGHTS THAT LIVE IN THE LONG TERM After fifty decisions, the patterns appear. After a hundred, they're hard to ignore. Reckon surfaces them: where confidence overshoots outcomes, where it undershoots, which domains your judgment is sharp in, and which ones still need work. RESOLUTION, THEN A SECOND LOOK When a decision resolves, you log what happened, whether the call was correct, and how satisfied you are with it. Thirty to sixty days later, Reckon asks again: would you make this call again? The two answers are rarely the same. CHECK-INS FOR THE MIDDLE OF A DECISION Between making a call and finding out how it went, things change. Check-ins capture new information — tagged positive or negative — and update your confidence. The middle of a decision is where the information arrives, and Reckon keeps it in the record. RESOLVED DECISIONS, AT A GLANCE Browse the calls you've made. Filter by domain, by satisfaction, by whether your follow-up still agrees with you. The library you wish you'd been keeping for years. ONE LIST, BY REVIEW DATE Every open decision, organized by when you said you'd come back to it. No notifications competing for your attention. Only the calls awaiting your next look. A TIMELINE PER DECISION Each decision has its own confidence chart: check-ins as points, tagged shifts as annotations. Watch the moment your thinking changed, and what changed it. BREAKDOWNS BY DOMAIN Career, finances, health, personal. Each domain has its own calibration curve. See them separately, then compare. Reckon is iPhone and iPad, one-time purchase. Buy it once and it's on every device you sign in with. Your data syncs over iCloud. Nothing of yours sits on a server we run. No subscription. No account. Less journaling, more calibration.

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
