Ad block and adblock browsing meet vocabulary learning in Palimpscape. Replace ads with words as you browse, learn rare vocabulary, study a new language, or practise your own word list. Palimpscape is a web browser that transforms advertising spaces into opportunities to learn. Instead of simply hiding detected ads, it replaces their placements with words selected from your chosen vocabulary. CHOOSE HOW TO LEARN • Learn rare words in your native language • Learn vocabulary in a new language • Add your own words, descriptions and translations • Choose from multiple difficulty levels • Hide words you no longer want to see LEARN WHILE BROWSING Words appear naturally in the spaces previously occupied by ads. Their size adapts to each placement, keeping pages readable while making vocabulary visible throughout your normal browsing. Tap a word to view its available definition. When learning another language, open a translation for the selected word in your preferred language. A COMPLETE MOBILE BROWSER • Browse websites using multiple tabs • Sign in to websites normally • Navigate with familiar browser controls • Block advertising network requests • Replace detected ad placements with vocabulary • Use regional ad block filter lists based on page and device language YOUR WORDS, YOUR PROGRESS Create a personal vocabulary list with an optional definition or translation for every word. Manually added words are shown more frequently, helping you focus on the vocabulary that matters most to you. Palimpscape tracks how often each word has appeared so that your vocabulary stays varied. If a word is no longer useful, hide it permanently with a single action. Turn everyday web browsing into language learning. Adblock distractions, replace ads and discover a new word on every page.

About

SideSpace

Features
Read full description

SideSpace keeps several separate environments on one iPhone. Each Space has its own web sessions, its own notes, its own photos, and its own lock. TWO ACCOUNTS, ONE PHONE Sign in to the same service twice — one account in your Work Space, another in Personal — and the two never see each other. Each Space keeps its own cookies and its own sign-ins, so switching Space switches everything at once. No signing out, no re-entering passwords. WHAT LIVES IN A SPACE • Web apps you pin, each opening straight to the service you signed into in that Space • A browser for everything else, with its own tabs and history • Notes • Photos and videos, kept inside the Space and never added to your Photos library • A camera that saves directly into the Space it was opened from PRIVATE SPACES A Space can be marked Private. Private Spaces are not listed at all until you unlock them — their names stay hidden, not just their contents, so handing someone your phone does not show them what you keep separate. Unlock with Face ID, or with a passcode that is separate from your iPhone's own code. YOUR DATA STAYS ON YOUR PHONE There is no account to create and no server to sync to. Everything a Space holds is stored on your device. Export a backup to a file whenever you want one. STARTS WITH SOMETHING USEFUL Pick what a Space is for — work, selling, studying, creating — and it arrives with the apps that usually go with it. You see the full list and approve it before anything is created. A PROXY PER SPACE Spaces already keep separate logins, but they share one connection. Point a Space at your own proxy and its web traffic leaves by its own route, while your other Spaces are untouched. You bring the proxy — SideSpace runs no servers and sells no bandwidth. A NOTE ON WHAT THIS IS SideSpace runs services in isolated web sessions. It does not clone or modify any app, and it is not affiliated with, endorsed by, or sponsored by any service you add. Web sign-ins are not included in backups, and web push notifications are not available in a web session — if you need alerts from a service, keep its own app installed alongside. SideSpace Premium unlocks unlimited Spaces, private Spaces and the in-app camera. • Monthly — $2.99 per month • Yearly — $19.99 per year, with a 7-day free trial • Lifetime — $39.99, one-time purchase (not a subscription) Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Payment is charged to your Apple Account at confirmation of purchase. Manage or cancel anytime in Settings > Apple Account > Subscriptions.
