Tell it once. Ask later in your own words. Ruema is the app that remembers for you. Tap the orb, say the thing you will forget, and it is kept. Days later, ask in plain language and Ruema finds it. No folders, no tags, no filing. Built for ADHD brains and anyone carrying too much in their head. HOW IT WORKS Tap the orb and speak. Ruema transcribes on your device, gives the thought a title, and files it for you. Where the spare key is. What the dentist said. The gift idea you had in the car. Ask later: "Where did I put the key?" and the answer rises to meet you, with how sure Ruema is and when you told it. THE ARK Anything sensitive can live behind Face ID or your passcode. Ruema notices when something sounds private and offers to lock it. Asking about it later means proving it is you first. TODAY A planner that stays out of your way. Add a task in one line, drop it on any day, and move it with a swipe when life changes. Jump to any month or year, then come straight back with one tap. Anything unfinished from past days waits at the top of Today so nothing slips away. Finished things are kept in the Harvest, by the day you did them. THE WATCHMAN Set a reminder on any task. When you move the task, the reminder moves with it. When you finish, it goes quiet. INVISIBLE BURDEN A place for thoughts with no day attached. Drop what is on your mind, then drag it onto a day when it becomes a plan. KAIROS A focus timer inside every task. Pick your minutes, stay with it, and finish strong, even if you switch apps. THE VAULT Your passwords, stored in the Apple Keychain and opened with Face ID or your passcode. Ruema never sees them. PRIVATE BY DESIGN Transcription happens on your iPhone. Memories sync through your private iCloud. No ads, no tracking, no account to create. When you use AI recall, only the handful of memories most relevant to your question are sent to Ruema's server to compose an answer, and nothing is kept there. FREE AND PLUS Free includes voice capture for up to 50 memories, 10 AI recalls a month, on-device search, the Ark, 10 active tasks, 5 categories, 3 reminders, Invisible Burden, Kairos, the Harvest, Numbers, and iCloud sync. Ruema Plus removes every ceiling: unlimited memories, unlimited AI recall, unlimited tasks, categories and reminders, plus the Vault. Ruema Plus is $4.99 per month or $39.99 per year, with a 7 day free trial on the yearly plan. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings. Ruema is not a medical device. It does not diagnose, treat, or cure ADHD or any other condition. If you have questions about ADHD, please talk with a qualified clinician.
