Aimo Pointer vs Guyun

Aimo turns your iPhone into a wireless laser pointer and presentation remote for your computer. Move your hand, and a glowing red dot follows on the big screen — just like a real laser pointer. Hold to draw highlights over your slides, flip pages, and zoom, all from the phone in your hand. Wearing an Apple Watch? Point and control your presentation right from your wrist. HOW IT WORKS Open the free Aimo companion app on your Mac or Windows PC, open your document, and scan the QR code with your iPhone. That's it — no accounts, no setup, no cables. POINT NATURALLY Aimo uses your phone's motion sensors to move the pointer the way you'd point a finger. Smooth, responsive, and precise — it feels like the laser is coming out of your phone. HIGHLIGHT AS YOU TALK Hold the highlight pad to draw over your slides in real time. Circle a number, underline a sentence, mark what matters. Your marks stay on each page as you navigate, and clear with a tap. WORKS WITH YOUR DOCUMENTS Present PDF files, plus Word, Excel, and PowerPoint (using the free LibreOffice helper on your computer). Open a document on the desktop companion and present it fullscreen with your pointer on top. APPLE WATCH INCLUDED Leave your phone in your pocket. The Aimo watch app lets you point with your wrist, change slides, and highlight — a presentation remote you literally wear. PRIVATE BY DESIGN Everything happens on your local Wi-Fi network. No cloud, no servers, no accounts, no data collected — your documents never leave your computer. PERFECT FOR Presentations and pitches Lectures and classrooms Team meetings and reviews Any time you'd reach for a laser pointer Aimo requires the free desktop companion app for Mac and Windows, available at aimo-app-pointer.web.app

Guyun keeps your files in object storage you own: Alibaba Cloud OSS, Tencent Cloud COS, Qiniu, Upyun, Backblaze B2, Cloudflare R2, MinIO, or any S3-compatible service. No account system, no server of ours, no telemetry — files go straight from this device to your own bucket. The app provides no cloud space and takes no cut of your storage. ■ Why "your own storage" Most cloud drives keep your files on the vendor's servers, which decides the speed, the capacity and the price. Guyun is the other way round: the bucket, the keys and the bill are yours, and your provider bills storage and traffic at its published rates. Guyun never bills you for either. ■ What it does · Browse and manage: grid or list, sorted by name, date or size; whole-bucket search, not just the folder you are in; new folders, rename, copy, move · Upload and download: from Files or Photos, or a whole folder at once, through a queue you can pause and resume; downloads go to a folder or to Photos · iOS background transfers: files up to 200 MB go to the system as one request and finish even if you switch apps or lock the screen; larger files continue with the background time granted · Progress anywhere: a small pill shows how many transfers are running and how far along they are · Usage ledger: how much Guyun itself moved — today, this month and last month, by bucket and by device, with cellular counted separately on this device. Only this app's transfers, never your provider's bill · Storage size: measure a bucket to get its file count and total size; a large bucket can be finished over several taps, and the result stays on this device · Archive files are marked; the app asks before a restore (how long, billed by your provider, cannot be cancelled), and afterwards preview and download work as usual · Preview: zoom images, play video while it is still loading, open PDF and text · Trash: a delete moves the item to the bucket's own trash folder, where it can be restored or removed for good · Several devices: the same bucket on iPhone, iPad and Mac; hand a configuration over by scanning a code instead of typing keys · Make it yours: an icon per storage, a sidebar you can reorder, and storages you do not need hidden away (back in Settings → Storage service) · Locks: Face ID / Touch ID for the whole app or one storage; transfers keep running while locked, and turning a lock off always asks for authentication first ■ Privacy, in plain terms · No account and no server of ours: the app talks to the storage address you enter, and to nothing else · Access keys live in this device's Keychain, never uploaded to us and never synced through iCloud · Keys leave the device only when you deliberately hand a storage to another device: the handoff code contains them in plain text, so show it only to your own device and treat it like a password · No usage data collected; no third-party SDKs, no analytics, no ads · Face ID / Touch ID is handled by the system, and that data never leaves your device · Both locks are screen gates, not encryption: they keep out someone who picks up your unlocked device ■ Try it without any storage A local demo storage is built in: sample photos, a video and a PDF are generated on device. No account, no keys, no network — browse, preview, upload, rename, copy, move, delete and restore, all without a single credential. ■ What you need A bucket, and a key pair allowed to use only that bucket. Pick the service and place and the app fills in the endpoint and region; you enter the bucket name and the keys (Tencent COS also asks for the APPID ending its bucket names). Guides for every service are on our website, including an Alibaba Cloud template that creates the bucket, the RAM user and the keys at once. ■ Languages Simplified Chinese, Traditional Chinese and English (switch in Settings; applies next time you open the app).
