Generating… usually about a minute.
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.

DrPeptide is a private, offline peptide reference and dose log for people already following a protocol. Look a compound up, log the dose from the same card, and let the app remember what you took, when, and what's left in the vial. No account, no analytics, no server: your log never leaves your phone. DrPeptide is not a medical device. It does not diagnose, treat, cure, or prevent any medical condition, and it does not prescribe or recommend any substance or dose. Reference figures come from drug labels, clinical trials, and published community protocols, and are shown as ranges with their status — never as a prescription. Consult a qualified healthcare professional for medical advice, diagnosis, or treatment. PRIVATE BY DEFAULT Everything is stored on your device. There are no accounts, no servers, no analytics, and no ads — the app makes no network requests of its own. Nothing is backed up to the cloud. You can lock it behind Face ID / fingerprint or your device PIN. You own the data: export it as JSON (full backup), CSV (dose log) or a calendar file (schedule), and import it back on a new device. Exports happen only when you tap the button. WHAT IT DOES • Reference library — 132 compounds with mechanism, evidence notes, cautions, FDA approval status, and WADA anti-doping status on every card. Search by name, brand name or goal, filter by WADA status or route, and star favourites. Compounds that are not FDA-approved stay hidden until you switch them on. • Dose log — one simple sheet, opened from Home, the Log tab, or "Log a dose" on any reference card. Backdate a dose, add a site and notes, and see every day on a month calendar. • Protocols — daily, weekly, every other day, every N days, or N days on / M days off. Today's due doses wait on Home. • Vials and inventory — remaining mg, expiry countdown after reconstitution, run-out projection, and optional cost per dose. • Reminders — one daily reminder at a time you pick, plus low-stock and expiry flags. Notification text never names a compound. • Insights — 30-day adherence, streaks, dose history and a month calendar. • Optional extras — switch on only what you use in Settings → Features: weight and bloodwork charts, an injection-site body map with rotation suggestions, and on/off cycling with titration ramps. • Offline localization — the complete interface and reference catalog are bundled in 25 languages: Bulgarian, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Irish, Italian, Japanese, Latvian, Lithuanian, Maltese, Polish, Portuguese (Portugal), Romanian, Slovak, Slovenian, Spanish, and Swedish. ONE PURCHASE. THE WHOLE APP. One upfront purchase unlocks the complete app. There is no subscription, advertising, account, protocol limit, or separate feature tier.

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.
