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

The app operates like a real electronic keyer with a dual-lever paddle, dot and dash memories and various keying modes including "iambic". It produces a series of short sound signals (dots) when one of the paddles is pressed and a series of long signals (dashes) when the other one is pressed. Letters, digits, procedural signals (prosigns) and other transmitted symbols are displayed on the screen. Additionally, Morse code abbreviations used in amateur radio, maritime, aviation and military communications are recognized and formatted appropriately. ADVANCED CW KEYER The keyer buffers paddle presses, that eases the manipulation and helps to transmit at higher speeds. High accuracy of generated signals contributes to high-quality transmission of Morse code. Keying modes: - Ultimatic — "last paddle wins" - Iambic (modes A and B) - Single lever - Semi-automatic, aka "bug" EXTENDED MORSE CODE When displaying the transmitted text, the app "knows" in addition to International Morse code a number of extensions for different languages. Supported alphabets include Japanese (Wabun code), Greek, Cyrillic-based and Latin-based alphabets with diacritical marks. The app recognizes details and nuances of Morse code for the following alphabets: Belarusian, Bosnian, Bulgarian, Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Finnish, French, German, Greek, Hungarian, Icelandic, Italian, Japanese, Latvian, Lithuanian, Macedonian, Moldovan, Montenegrin, Norwegian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Turkish, Ukrainian. SMART DISPLAY MorseKeyer does a lot to display the Morse code you transmit in the most readable form. For this purpose the app is equipped with the following functions: - Sophisticated text formatting - Dynamic switching between alphabets - Reasonable representation of errors These innovative features use multilevel content analysis to detect CW abbreviations, Q-codes, Z-codes, amateur radio callsigns and other special words. SOPHISTICATED TEXT FORMATTING The transmitted text can be displayed not only in the traditional all-capital format, but also using a kind of "smart" formatting. In this mode each word is displayed in the accepted form, as in the following CW session snippet: GM dr OM tnx fer call = ur RST is 599 = my QTH is nr London DYNAMIC SWITCHING BETWEEN ALPHABETS Even if you choose to use a non-Lating version of Morse code in your communication session, special words and Morse code abbreviations still can be displayed in Latin script. - In Wabun code the prosigns DO and SN as well as codes for Japanese parenthesis indicate switching between International and Japanese alphabets. MorseKeyer follows this convention and switches alphabets in such cases automatically. - A Cyrillic alphabet can be selected as the primary one to display most of the transmitted text, but all Morse code abbreviations and special words (CQ, de, ur, RST, my, QTH, name, tnx, etc.) as well as callsigns can still be represented in Latin script. REASONABLE REPRESENTATION OF ERRORS If you transmit a non-existent Morse code sign, the app displays it either as a dot-dash sequence or in another form depending on the current settings. In many cases MorseKeyer highlights a mistake, indicating its source and making it readable. ADVANCED SETTINGS MorseKeyer is ready to use out of the box. However, it has a lot of settings allowing you to fine tune it, customize and make more convenient in different use cases. NICE SOUND A special attention in the app is paid to the sound signal quality, its timbre, the optimal level of clicks and other characteristics, that make the sound of Morse code authentic and recognizable by any radio operator and comfortable to listen to.

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.
