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.

Safely stash your files, photos, videos, and notes, using a personalized passcode. Whether it’s a scanned copy of your passport, sensitive work documents, or private memories, storing them in Safestache adds a much-needed layer of protection. Instead of keeping passwords in your Notes app or leaving personal photos in your regular gallery, you can now store them behind encryption inside Safestache, where they’re kept away from the cloud and from anyone snooping through your phone. Everything you import, whether it’s an image, a video, a text note, or an audio recording—is fully encrypted and securely stored on your device. No one, not even us, has access to your data. Your privacy isn’t a feature, it’s the foundation. There are no subscriptions, no ads, and no in-app purchases. When you buy Safestache, you get the full experience upfront. There’s nothing else to unlock, and no hidden fees to worry about later. It’s a one-time purchase, and it's yours forever. We don’t believe your privacy should come with strings attached or monthly payments. Hang on to old memories and track your gym progress selfies without cluttering your photos album. Create notes with your private thoughts, holiday gift ideas, and bank information. Import a variety of file types including pdf, mp3, and mp4. Store tax information, private voice memos, and other important documents you don’t want others to find. No internet connection is required to access your content, and everything stays local to your device, so you're never dependent on external servers or cloud storage. Even if your device is offline, your files are always within reach and always protected. Key Features: Decoy Vault: Create a decoy passcode to hide real photos and videos. Show snoopy friends your decoy vault, while your real albums are disguised behind a different passcode. Break In Alerts: View alerts for unexpected intruders that attempted to access your stash. The date and time, as well as a picture of the intruder can be displayed in the settings. Disguise Mode: When an intruder tries to access your stash, after multiple incorrect attempts, they are shown a fake error message to protect your data. Quick Hide: Place your device face down on the table to secretly close the app. Private Browser: Use the web browser within the app to privately access websites. Keep your browsing history hidden from other browsers. Gallery: Create custom albums within your gallery to organize, view, and play, your hidden images and videos. Notes: Securely store your secret notes, from private thoughts to passwords. Documents: Navigate confidential documents and audio with a secure file browser.

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.
