What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

drum tuner EZ clears your heads & locks in real drum tones, without wasting ear-sweat. Jamming in the garage? Rushing a soundcheck? Tracking in the studio? 〉 2-STEP TUNER: 1. Tension by feel >> get close by ear. 2. Fine-tune each lug >> match pitch and you’re done. No gimmicks, no voodoo. Just snares that crack, toms that sing, and kicks that punch. 〉 Why drummers grab drum tuner EZ • 'cause duct tape isn’t tuning, bro! • Your snare finally sits where the producer wants it • Clears heads before your guitarist finds the right pedal setting • Cheaper than a 'pro' drum key, but the app works with the free one you received with your kit too • Cleaner than your cymbals • Easier than explaining 7/8 to your bass player • Snare, toms & kick sounding tight, also when fills get loose :p 〉 Key Features • Lug tuner for 4–10 lugs • 0,5 Hz accouracy rounded to 1 Hz accuracy | Detects 30–550 Hz drum pitch... No other tool does.. except Drumtune PRO. • Modes for snare reso, snare, tom, floor tom & kick • Custom mic sensitivity + color settings • Runs on iOS 17 to 26+ (if it runs nowwadays TikTok, it runs this.) 〉 From Stage to Studio Believe it or not: the more you use this drum tuning app, the more your ear learns. It's like pitch-gym for drummers. Tuning more often sharpens your awareness of how head tension shapes tone. Soon you’ll hear every change in snare, tom & kick pitch! Result? A sharper ear, tighter kit, smoother gigs, and the confidence your kit sounds pro... even when your chops are still in practice mode. For those who doubt>> Clearing a drum head to perfection is just a part of getting a good sounding kit. It doesn't matter whether you clear a drumhead by ear, with a tension-measuring device, or with a pitch based tuner. You decide on how your drums should sound. Cleared drum heads sound good, like cleared drum heads do! Drumheads don't care about how you cleared them: they sound the same either way. While clearing is an important step of 'drum tuning', it is just a part of how you get great sounding drums. You could clear heads perfectly and still get a "meh" drum sound for your needs, because didn't clear the heads in the right 'spot' to achieve it. To get your kit sounding 'great', it matters "where" you clear each drumhead: a) "where" in its tensioning range for its diameter and head type, and b) "where" tonaly, towards the opposite head, c) so that the drum sits nicely between the other drums in your kit, d) while having a playing feel and tonal decay dynamic that pleases you.... You tune for your moodzzzz. Once you tuned enough drums, you'll realize the above makes sense like grabbing a cup of coffee in the morning. We leave you to explore, drumtuner EZ is a tool to help clear drumheads. It's support for that facet of the process to get to the sound you're after. drumtuner EZ is not your travel guide, but should you embark on the drum tuning journey, you may find in this tool a great travel-companion instead.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
