Gravity keeps all your notes in one stream, with the newest at the top. As you add more, older notes sink down the list. When one of them still matters, swipe it right and it comes back to the top. The idea comes from Andrej Karpathy's append-and-review note: write everything in one place, read back through it now and then, and move up whatever you still care about. Gravity has no folders, so there's nothing to file. Writing The cursor is waiting at the top when you open the app. Type your note and press Return twice, or tap the add button. A half-written draft stays where you left it. Rescuing and tidying Swipe right on a note to rescue it. Swipe left to archive, delete, share or copy. Archived notes have a page of their own, and deleted notes stay in Deleted Notes until you restore them or clear them out. Markdown and checklists Headings, bold, italics, lists, links and quotes show formatted in the stream. Start a line with "- [ ]" to make a checklist, then tick items off without opening the note. In the editor the formatting appears as you type, and a small bar above the keyboard adds headings, bold, lists and checklists. Everything is saved as plain Markdown text. Tags Start a note with todo:, idea:, read: or any word followed by a colon, and it gets a colour of its own. Type todo: into search to see only those notes. There's no tag manager to look after. Search Search covers every note on your phone, archived ones too, and works offline. It matches parts of words and ignores accents. Getting notes in The Home Screen widget starts a new note or pastes in whatever you last copied. You can also share text or a link from another app, and it becomes a new note at the top of the stream. Privacy Your notes are stored on your iPhone. Gravity has no accounts and no analytics, and it doesn't collect any data. If you want your notes on your other Apple devices, turn on iCloud sync; it also works with Gravity for Mac, which is sold separately. You can export everything as JSON or Markdown at any time. Looks Choose light, dark or OLED black, or follow the system, and pick from three text sizes. There's a stats page too, worked out on your phone, of course. Price You pay once. There's no subscription, no in-app purchases and no ads. Privacy policy: https://www.gravitynotes.app/privacy-policy

Every great Relay deployment starts on-site — and Relay Admin is what gets it there. Relay Admin is the field companion for the technicians and administrators who roll out Relay. Map a building, configure indoor positioning, and provision your whole team — all from your phone, all before you leave the parking lot. BUILD YOUR SITE, FLOOR BY FLOOR Create buildings, floors, and rooms in a few taps. Drop a building on the map with address search and precise geocoding, then nudge the pin until it's exactly right. Your entire site structure lives in one place, ready for the rest of the job. INDOOR POSITIONING THAT HOLDS UP Add beacons by scanning a QR code or entering a MAC address, then confirm placement with live proximity ranging — no guesswork about whether that beacon made it onto the right wall. Auditing an existing room? Range for every beacon you expect, see what's missing at a glance, and clear out the stale ones. Prefer Wi-Fi? Use a Relay device as a scanning proxy to capture access-point fingerprints for any room, then confirm that room resolves correctly before you call it done. VERIFY BEFORE YOU WALK AWAY Room verification closes the loop. Point a proxy device at a configured space and watch it resolve to the right room — real validation, on-site, while you can still fix it. PROVISION USERS IN MINUTES Create users with a guided, step-by-step flow: pick a team, assign channels, set workflow groups, review, submit. Manage the whole roster from the same app — assign and unassign devices, rename users, handle seats, and remove accounts one at a time or in bulk. TAP TO PAIR NFC PROFILES Pair NFC tags to user profiles with a single tap. Built for shared-device environments where the right profile needs to follow the right person. BUILT FOR THE WAY YOU WORK Permissions follow your Relay account, so every technician sees exactly the tools they're cleared for and nothing they aren't. Relay Admin hands off to the Relay app when you need it and picks up right where you left off when you come back. Lost signal mid-job? Relay Admin refreshes the moment you reconnect. Relay Admin is designed for Relay customers and partners. A Relay account is required to sign in.
