An inventor's workshop that runs entirely on your iPhone. Support & contact.
Nothing you write leaves your device. There is no account and no server of ours. The only thing that ever goes out is a literature search you start yourself.
Questions, bug reports and refund questions: brkekahraman@icloud.com — usually answered within two business days.
The cheapest way an idea can die is by already existing. Forgn recognises 146 established arrangements by name, searches Crossref and arXiv live, and prepares queries for Google Patents, Espacenet and Lens so you can check the patent record yourself.
It takes a distinctive term from one of your notes and applies it to a real mechanism in another — only when the two share genuine common ground. Every suggestion says what moved, where it came from, and what connects them.
Not a build manual. Forgn turns an idea into the order in which it could die: prior art first, then each known failure mode, most fatal and cheapest-to-test first. Every step says what to measure and asks you to write the threshold down before you run the test.
Thirty-eight documented failure modes, each triggered by an actual design choice, each with alternatives and a reason. These are free, always.
A map of your own archive: buildings are the mechanisms your notes use, and the figures walking between them are the notes themselves. When two meet you get a real transfer candidate.
Because there is nothing to sign in to. Your archive lives in this app on this device. No account means nothing to lose, nothing to leak, and nothing to pay for in the background.
Everything except the literature search and web clipping works with no connection at all — the engine is on your device. Those two features need a connection because they read public databases and public web pages.
Settings → Export writes your whole archive as a JSON file you can save or send anywhere. Export keeps working even after a subscription ends.
Archive → Scan Page → tap the text box, then choose Scan Text on the keyboard. Your iPhone's own text recognition reads the page and writes it into the box. The photo is never saved and never sent — the app never receives an image at all.
Free: your archive up to 25 entries, prior-art checks, reality walls and the coverage map. Pro: cross-pollination, risk-ordered plans, unlimited archive and export. Bad news is always free — a warning you did not see because you had not paid would be a warning working against you.
That is the most useful thing Forgn can tell you, and it is not a stop sign. It moves the question: find the published limit of the known version, and make your contribution the specific thing you add to it.
Town is built from mechanisms your notes describe. A note that says what something is but not how it works has no place to stand yet. Add a sentence about the mechanism and it appears.
Subscriptions are managed by Apple, not by us: iPhone Settings → your name → Subscriptions. Cancelling there stops future charges. Your archive and your export stay with you.
