Scan a page with the camera, or open a photo or PDF 2. Drag over the passage you want to read 3.

Streamscription
Read full descriptionHide full description
Your subscriptions, organised the way you actually watch. Streamscription collects the YouTube channels and playlists you care about into clean, themed feeds — so you can see what's new in seconds, instead of letting an algorithm decide for you. GROUPS THAT MAKE SENSE Create groups like Tech, Cooking or Music and file your channels and playlists inside them. Drag to reorder. One glance shows everything new, sorted by topic instead of dumped into one endless stream. WATCH LISTS, NOT A BLACK HOLE Save anything for later into as many lists as you like — "Podcasts for the commute", "Watch with the kids", whatever fits how you watch. Mark videos as watched, clear out the ones you're done with, move them between lists. FIND IT INSTANTLY One search covers your channels, your playlists, your saved videos and the latest videos across all your feeds. SYNCS BY ITSELF Your groups and lists stay in sync across iPhones through your own iCloud account. No sign-up, no password, no server of ours in the middle — your data never touches our infrastructure, because we don't have any. SHARE A WHOLE GROUP Send a friend your entire "Cooking" group as a single link. One tap on their side adds every channel in it. ADD FROM ANYWHERE Share a channel straight from the YouTube app into Streamscription, or just paste a link. Channels and playlists both work. WORKS OFFLINE Feeds are cached on your device, so your lists open instantly even with no signal. PRIVATE BY DESIGN No account. No ads. No analytics. No tracking of any kind — not even anonymous. Streamscription has no backend at all, so there is nowhere for your data to go. Everything stays on your device and in your personal iCloud. GOOD TO KNOW Streamscription organises videos and links to them; it does not play them inside the app. Tapping a video opens it in the YouTube app or your browser, where creators get their views and their revenue. Streamscription is an independent app. It is not affiliated with, endorsed by or sponsored by YouTube or Google LLC.

Verdict
The clearest difference is in-app purchases: Streamscription at none against RubiMask's 3. Streamscription also leads on ads (none vs shown) and iOS requirement (15.0 vs 17.0). On price, update cadence and device support there is nothing between them.
