Regain vs Arity One

Can't study without checking your phone every five minutes? You're not the only one. Regain is the focus app built purely for students - block the apps that distract you, start a focus timer, and finally get through a study session without Instagram or YouTube pulling you away. Whether you're preparing for board exams, college entrance tests, or professional certifications, Regain helps you put in the hours. FOCUS TIMER Set a timer, lock in, and study. Choose your duration and tag each session by subject (Physics, Organic Chemistry, or whatever you're on). POMODORO TIMER (PRO) Stay focused and get more done with the classic Pomodoro technique. Focus, recharge, repeat - customize your focus and break durations, with support for both short and long breaks. BLOCK DISTRACTING APPS When you start a focus session, Regain blocks the apps you choose - like Instagram, TikTok, YouTube, Snapchat, Reddit, and Twitter/X - until your timer ends. Powered by Apple's Screen Time, so Regain never sees which apps you block or accesses your screen time data. STRICT MODE (PRO) For students who want an extra layer of self-commitment. When you turn on Strict Mode, your session runs for the full duration you selected - helping you build the habit of finishing what you start. Enable or disable it anytime from Settings. FOCUS GUARD (PRO) An opt-in reminder that helps you follow through when willpower dips during a focus session. You stay in control - toggle Focus Guard on or off anytime from Settings. FOCUS STATS Watch your focus improve day over day, with a per-subject breakdown so you know exactly which subjects got your attention. FOCUS MUSIC (PRO) Science-backed sounds built for concentration: Lofi Beats, Deep Focus Ambience, White Noise, Space, and Binaural. THEMES (PRO) Personalize your focus screen with beautiful Nature and Lofi wallpapers. FREE VS PRO The free tier includes unlimited focus sessions and a stopwatch. Regain Pro unlocks Pomodoro, Strict Mode, Premium Themes, and Science-Backed Focus Music. PRIVACY Sign in with Apple or Google is optional — signing in syncs your subscription across your devices. Your focus data always stays on your device, whether you sign in or not. Regain uses Apple's Family Controls to block distractions and never sees the names of the apps you block. You can permanently delete your account at any time from Settings.

Arity opens and you draw. No account, no manual, no setup screen. Pick a diagram type and sketch the way you would on paper. Each type already knows its own notation, so you never have to remember which shape means what or which arrow is allowed where. Arity handles that. You handle the thinking. FIVE DIAGRAM TYPES • Freestyle: a blank canvas, no rules. • Flow chart: Terminal, Process, Decision, I/O, Connector. Break a rule and it says so: only Decision and Connector may branch. • Class diagram: class, abstract, interface; fields and methods; association, aggregation, composition, inheritance, implementation, with multiplicities. Checked against OOP: missing abstract methods, inheritance cycles, interfaces used wrongly. • ER: both crow's foot and Chen, one button apart. • Mind map - official style: one central idea, organic tapering branches, one keyword each, colour inherited down the branch. The diagram argues back when the thinking is wrong. That is the difference between a drawing tool and a thinking tool. APPLE PENCIL Strokes follow your pressure, smooth down to every sampled point. Rest your whole palm on the glass and keep drawing. Two fingers pan and zoom; a second finger undoes whatever the first one just started, so you never nudge a shape by accident. Press and hold stands in for a right click. No Pencil? A finger draws just as well - and Settings lets you decide whether a finger should draw or move the canvas. ONE PROJECT, ONE FILE A whole project lives in a single document with its own folders inside it. It sits in Files under On My iPad › Arity, so backing it up, sending it on, or opening it from iCloud Drive works like any other document. Every change saves itself after a second or so, when you switch diagrams, and when the app goes to the background - written to a temporary file and renamed, so a half-written project is not a thing that can happen. PRESENT ON AN EXTERNAL DISPLAY Plug in a screen and the Present button appears. The external display shows only the diagram while your iPad keeps its toolbar and panels. Not mirroring. ALSO • Arrows bind to shapes and follow them as they move or resize. • Combine shapes with union, intersect, subtract and exclude. • Export PNG from 1x to 4x, transparent or on a colour you choose. • Library: save a selection as an asset and drag it back out later. • Notes, images, groups, undo/redo, minimap. • The entire app is under 5 MB.
