How Memory Watch Works Memory Watch searches publicly available information — including Wikipedia and the US Social Security Administration — to help you learn more about people from your past. Search Tips Enter a first and last name and tap Find Out. If you get too many results, tap + Add more details to add a middle initial, birth year, or suffix to narrow your search. Watchlist & Alerts The Watchlist is where you can add a person if no sign of passing is found, or no information is available. Memory Watch will alert you in the app when new public information becomes available. Memories When information indicates someone has passed, you can save them to your Memories for future reference. Account & Data You can delete your account and all associated data at any time from within the app under Info → Account Removal. Information Coverage Memory Watch uses publicly available information, including Wikipedia and the U.S. Social Security Administration. Information may not always be complete or up to date.

Sidekey turns your iPhone into a customizable wireless keyboard and shortcut pad for your own computer. Tap keys on your phone and they type on your Mac or Windows PC over your local Wi‑Fi — no extra hardware, no cables. Design the keyboard you actually want: add keys, build shortcuts (including combos like Cmd/Ctrl, and left/right modifiers), arrange them on a grid, and switch between layers and modes. Keep your most-used shortcuts one tap away. HOW IT WORKS Sidekey works together with a small, free desktop helper you run on the computer you want to control. Put both devices on the same Wi‑Fi, scan a QR code once to pair, and you're connected. Pairing is secured with a token, and your keystrokes travel directly to your own computer — never through us. FEATURES • Custom key designer — make your own keys, shortcuts, and layouts • Shortcuts & combos — Cmd/Ctrl/Alt/Shift, function keys, media keys, and left/right‑specific modifiers • Multiple layers & modes — flip between a full keyboard, a shortcut deck, a trackpad, and more • Trackpad mode — use your phone as a touchpad with left/right buttons • Voice typing — dictate with the system keyboard and send the text to your computer • Quick pairing — scan a QR code; reconnects automatically afterward • Works with Mac and Windows • Private by design — no account, no tracking, nothing sent to the developer REQUIRES THE FREE DESKTOP HELPER Sidekey needs the free Sidekey helper running on your Mac or Windows computer. Download it from the link on our support page. Questions or ideas? We'd love to hear from you.
