Mito turns studying into a pixel-art RPG. Every flashcard you review powers a turn-based battle, every focus session earns rewards, and every study streak grows your team of biobuds. It's spaced repetition you'll actually look forward to. STUDY THAT FIGHTS FOR YOU Mito schedules your cards with FSRS — a modern spaced-repetition algorithm — so you review exactly what you're about to forget. Grade yourself the classic way, tap through multiple choice, or type your answer and let AI check it. BATTLE WITH WHAT YOU LEARN Answer cards to charge your party's abilities and take down bosses across a campaign and an endless mode. Get a card right and your biobuds strike harder. Studying and playing are the same loop. COLLECT & GROW BIOBUDS Earn eggs by studying, then hatch a collection of cellular heroes — each with their own abilities, personalities, and rarities. Level them up, build your team, and feature your favorite on your profile card. LOCK IN WITH FOCUS SESSIONS Run focus timers that reward deep work with in-game currency and eggs. An optional stay-in-app lock keeps you honest during a session. STUDY TOGETHER Add friends with a code or invite link, see who's grinding this week on the league, and create or join study classes to share decks. Go further with Mito Pro: co-op focus sessions and head-to-head PvP deck duels. YOURS, OFFLINE Study, battle, keep your streak, and earn rewards with no connection — your progress is saved on-device first and syncs when you're back online. Sign in to sync across devices, or play anonymously. EVERYTHING ELSE • Daily quests and streaks that keep you coming back • A home-screen widget for due cards, streak, and quests • Import your own decks or start from built-in starters • Account and all data deletable any time from Settings Whether you're cramming for an exam, learning a language, or building a daily study habit, Mito makes the reps feel like a game — because they are. Mito Pro is an optional auto-renewing subscription (monthly or yearly) that unlocks unlimited decks and classes, co-op focus sessions, and PvP deck duels. You can study the core game for free, forever. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://studymito.app/privacy

Eivil is a mobile web browser that turns your open tabs into a deck of cards. OPEN TABS AS CARDS Step back from the current page to see every open tab in one spatial deck. Swipe between equal-sized cards and bring the page you want back into focus. BROWSE WITHOUT COVERING THE PAGE Eivil's floating dock stays close to your thumb, follows the page edge, and moves out of the way when a website needs the keyboard or its own bottom controls. THE BROWSER ESSENTIALS - Search the web or enter an address in one field. - Go back, go forward, reload, and pull to refresh. - Open, switch, restore, and close multiple tabs. - Bookmark pages with their site icons. - Revisit browsing history. - Find text on a page, share a link, or copy its address. - Restore your open session after relaunching Eivil. YOUR BROWSING DATA STAYS ON YOUR DEVICE Browsing history, bookmarks, and your tab session are stored locally. No Eivil account is required, and you can clear browsing data from Settings. Websites you visit may apply their own privacy practices. Eivil focuses on a cleaner, more tactile way to move through the web—one card at a time.

Verdict
The clearest difference is in-app purchases: Eivil at none against Mito's 2. Mito's advantage is update cadence (every 3 days vs every 9 days). On price, ads, device support and iOS requirement there is nothing between them.
