You saved it. Now read it. SnackBack saves links, videos and images, then lets AI sort, tag and summarize them โ€” and brings a few back to you every day, so you actually read what you saved. SAVE WITH ONE SHARE Share from any app โ€” your browser, Instagram, YouTube, Threads. There is no folder to choose and no tag to type. AI FILES IT FOR YOU The moment something lands, AI reads it, files it into a folder, tags it and writes a summary. You never design a folder structure or keep a tagging system alive. VIDEOS GET WATCHED YouTube videos and Instagram Reels are summarized, so you know what is inside a long one before you give it twenty minutes. IMAGES GET READ Screenshots and carousel posts are read for the text inside them and turned into cards you can search. ASK YOUR LIBRARY "What was that marketing article I saved last week?" finds it. No title, no date, no exact keyword needed. IT COMES BACK TO YOU A few saved items return each day, summarized, in servings small enough to finish. Saving is where every other app stops. This is the part that makes the pile go down. WORKS OFFLINE Saves land straight away without a connection and sync once you are back online. WHO IT IS FOR - You save good posts from Instagram or Threads and never open them again - Links pile up in chat threads where you cannot search them - You started with Notion or Evernote and gave up on the upkeep - Your read-it-later list only ever gets longer SUPPORTED FORMATS Links (URL), images, and text notes. FREE AND PRO Free covers up to 30 saved items in total. Pro removes the cap and adds audio playback, library Q&A, and weekly reports. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period, and can be managed in your App Store account settings.

IO Mail

Read full description

IO Mail is an email app you don't just read โ€” you manage your mail with it. MAIL HUB Every launch starts with a summary of your day: unread mail, messages from important people, today's tasks, overdue items, follow-ups awaiting a reply and snoozed mail, all on one screen. MULTIPLE ACCOUNTS Bring Iyonosfer, Gmail, Outlook and any IMAP account into one app. See all inboxes together and give each account its own color and signature. RULES Create rules by sender, subject, attachment or size: move to a folder, label, flag, mark as read, mute notifications, notify with priority or create a task automatically. For Iyonosfer accounts rules also run on the server, so unwanted notifications never reach your phone. FOLLOW-UPS AND EXPECTED MAIL Get reminded when a mail you sent goes unanswered. Expecting a message? Create an expectation; it's marked when the mail arrives and you're alerted if it doesn't. TASKS, NOTES, SNOOZE Turn a mail into a task with a due date and add it to your calendar. Take notes and send them as mail. Snooze a message and it returns to your inbox when the time comes. LABELS AND IMPORTANT PEOPLE Group mail with colored labels. Mark important people so their mail stands out in Mail Hub. Send unwanted senders straight to junk. CALENDAR INVITATIONS Accept or decline meeting invitations and add them to your device calendar. INSTANT NOTIFICATIONS New-mail notifications arrive within seconds for Iyonosfer accounts. Other accounts are checked in the background at regular intervals. BUILT FOR IPAD In landscape, folders, the message list and the message sit side by side. PRIVACY AND SECURITY No ads, no tracking. Passwords are kept in the device's secure storage and mail content stays on your device. Lock the app with Face ID. Remote images never load without your permission. IO Mail is developed by Iyonosfer Yazฤฑlฤฑm Hizmetleri.
