The iOS build installs directly on your iPhone — no App Store, no TestFlight yet. It's an ad-hoc build, so only iPhones added to it in advance can install it.
Get in — two steps
Send me your iPhone — email me here and I'll register your device and rebuild.
Install from the link above — once your device is in, use the Install on this iPhone button or QR code. Trust the developer profile under Settings → General → VPN & Device Management if prompted.
Good to know
Why not TestFlight? TestFlight needs a full App Store Connect review setup; this ad-hoc build skips that for faster iteration.
New device means a new build — unlike Android, adding an iPhone means rebuilding so its device ID is included.
TestFlight is coming — a tap-a-link install with no registration needed, once the app's closer to store-ready.
What's in this build
Live, streaming replies
Every specialist assistant now answers in real time, word by word, instead of waiting for the full response.
Chemistry, fully equipped
Look up any compound in PubChem, balance equations instantly, and run molarity, dilution, gas-law and pH calculators.
Finance with live charts
Tap any stock or coin for an interactive price chart, search for any symbol, and see upcoming earnings.
A real writer's thesaurus
Synonyms, rhymes, near-rhymes and describing words — powered by Datamuse, right inside Selin Writers.
Law, Tech & Med research
Search U.S. Code statutes and read full court opinions, look up CVE vulnerabilities, and pull ICD-10 codes and PubMed literature.
Photos in chat, saved history
Attach a photo and ask about it in any assistant — and each one now remembers your conversation between visits.
