Rool gives you a private computer in the cloud that you can talk to. Ask questions, create files, solve problems, and work through projects with an AI that builds on what you’ve already done. Each Rool Machine brings your conversations, files, and memory together. It can run software and carry out tasks with multiple steps, helping you go from an idea to finished work through a familiar chat. WORK WITH YOUR FILES Upload documents, PDFs, images, spreadsheets, and code. Ask Rool to read, edit, organise, or create files for you. Turn notes into a report, work through calculations, or build an interactive HTML page. CREATE AND EXPLORE Draft ideas, generate images, write code, and compare different approaches. Refine the results through conversation and keep what you create alongside the rest of your project. BUILD ON YOUR WORK Rool connects your notes, conversations, files, and decisions through persistent memory. Return to a project with its context still available, and ask your AI to use earlier work when planning what comes next. MAKE ROOM FOR DIFFERENT PROJECTS Use separate Machines for personal projects, work, or shared interests. Each has its own files and memory, helping you keep different parts of your life organised. WORK TOGETHER Invite others into a Machine to collaborate with the same AI, files, and project history. Changes sync in real time, so everyone can work from the same information. PRIVATE BY DESIGN Your work is stored in your own isolated Machine, hosted in the EU. Rool has no ads and does not sell your data or share it for third-party AI training. You can export your data whenever you choose. AI INCLUDED Advanced AI is built in. Rool automatically selects models for the task, so you can focus on what you want to do. Start with a free plan that includes AI access, persistent memory, and file storage. Paid plans offer higher usage and storage limits.

Verdict
The clearest difference is ratings volume: Encrypted Email at 51K against Rool's 5. Encrypted Email also leads on chart position (#66 vs unranked). Rool's advantage is iOS requirement (15.0 vs 17.2). On price, rating, review sentiment and update cadence there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Encrypted Email sells 4 in-app purchases, starting at $5.99 per month and Rool sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
Encrypted Email holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Encrypted Email has 51K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 46% of Encrypted Email's written reviews are positive against 50% of Rool's, so the app with the better star average is not the one people write more warmly about.
Encrypted Email ships an update every 10 days, Rool every 6 days. Both last shipped on November 13, 2026.
