Cosyra gives you your own Linux computer in the cloud and a phone app built for running AI coding agents on it. Chat with Claude Code, Codex, Cursor or OpenCode while they work on your projects, browse the files they change, preview what they build, dictate by voice, and open a full terminal whenever you want one. YOUR OWN MACHINE • A persistent Ubuntu machine with 30 GB of storage. Your repos, tools, dotfiles and agent sessions stay exactly where you left them. • Sleeps when idle and wakes in seconds. • 4 GB of RAM on Core, 8 GB on Pro. Nothing depends on your phone's CPU or battery. • git, node, python and the rest of a normal developer toolchain, plus whatever you install. AGENTS, NOT A CHATBOT • Run Claude Code, Codex, Cursor or OpenCode on your machine and talk to them from your phone. • The agent edits files and runs commands with the permission level you choose. • Queue follow-ups, steer work in progress, and switch agents on the same project. • A running turn survives a dropped connection, and you get a notification when unattended work finishes. PROJECTS, FILES AND PREVIEWS • Link GitHub, clone repositories, open projects, switch branches, and inspect diffs. • Browse and read files without typing paths. • Preview the web apps your agents build through a secure, authenticated tunnel. VOICE • Dictate prompts. Speech is recognized on your device and tidied up before it reaches the agent. A FULL TERMINAL WHEN YOU WANT ONE • xterm-compatible terminal with smart keys, scrollback restoration and truecolor. • Sessions keep running while the app is in the background and reconnect where they stopped. BRING YOUR OWN MODELS Connect Anthropic, OpenAI or another supported provider with your own API key or eligible subscription. Your subscription pays for the machine, not the model. Cosyra never resells model access. PLANS Core (4 GB RAM) and Pro (8 GB RAM), both with 30 GB of storage and a 7-day free trial. A subscription is required for machine access. Pricing is shown in the app before you start a trial. PRIVACY AND SECURITY • Provider API keys travel over TLS to encrypted server-side storage and are never saved on your phone. • Every machine runs in its own isolated sandbox. • Voice recognition runs on the device. • Sign in with Apple, Google or GitHub. Claude Code is a product of Anthropic, Codex of OpenAI and Cursor of Anysphere; OpenCode is an open-source project. Cosyra is not affiliated with or endorsed by any of them.

PreGrade Ultra uses perspective correction to reduce the impact of camera angle on your centering measurements. **PERSPECTIVE CORRECTION** Other centering apps measure your photo as-is. If your camera is even slightly angled, your measurements can lose accuracy. PreGrade Ultra uses homography-based perspective correction to mathematically flatten your card to its true 63×88mm dimensions before measuring borders — centering analysis powered by computer vision. **PRECISION CENTERING ANALYSIS** - Measure left/right and top/bottom centering ratios - Millimeter-level border measurements - Front and back analysis with separate thresholds - Visual edge detection confirms your guide placement - Detect clockwise and counterclockwise print tilt **7 GRADING COMPANIES** Centering grades from PSA, BGS, CGC, TAG, SGC, ACE, and AGS. Every company has different thresholds — see which grade your card may qualify for at each one, with full threshold breakdowns. **CROSS-GRADE OPPORTUNITIES** Already have a graded card? See which companies may give a higher centering grade. The Understand tab highlights your potential best market-value grade at a glance. **MARKET PRICING** Look up active eBay listings for any Pokémon card. See current asking prices for raw and graded cards across most major grading companies. **BUILT FOR COLLECTORS, NOT ADVERTISERS** No ads. No banner spam. PreGrade Ultra is a tool built by a collector, for collectors. 3 free grading sessions included. Unlock unlimited access with a one-time Pro upgrade. **IMPORTANT:** PreGrade Ultra measures centering only. Card grading involves surface condition, corners, edges, and print quality — factors that cannot be assessed from a photo. Results are estimates and are not guaranteed to match any grading company's official assessment. PreGrade Ultra is not affiliated with, endorsed by, or sponsored by any grading company.

Verdict
The clearest difference is update cadence: PreGrade Ultra at daily against Cosyra's every 6 days. PreGrade Ultra also leads on rating (5.0 vs 4.7). Cosyra's advantage is ratings volume (13 vs 2) and iOS requirement (16.0 vs 26.4). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Cosyra sells 6 in-app purchases, starting at $20.00 per month and PreGrade Ultra sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
PreGrade Ultra holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Cosyra has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
Cosyra ships an update every 6 days, PreGrade Ultra daily. Both last shipped on October 25, 2026.
