Bubble makes Gmail feel less like an inbox and more like a conversation. See every Gmail thread as a clear, chronological exchange while correspondents continue to receive ordinary email. Built for clarity • Gmail thread IDs keep conversations correctly separated • Subjects stay available without dominating the screen • Exact visible recipients are shown before you send • Cleaned message text can always be reversed to the complete original • Search and filters help you find unread, starred, sent, file, and group conversations Clear old clutter safely with Bubble Sweep • Choose Promotions, Social, Updates, or Forums • Filter by age • Protect starred, important, or attachment mail • Preview the exact Gmail search and count before changing anything • Archive by default or move exact matches to recoverable Trash • Leave the Sweep screen or switch apps while work continues on supported iOS versions • Resume from a protected on-device checkpoint if iOS pauses the task • Undo completed changes Private by design Bubble processes and caches mailbox content on your iPhone. It blocks remote images, tracking pixels, scripts, forms, and active HTML by default. Bubble does not sell mailbox data or add advertising or analytics to the mail path. Disconnecting removes the selected account’s Bubble data from the device while the original mail stays in Gmail. Bubble Plus Optional purchases unlock up to eight Gmail accounts, more pins, private templates and signatures, saved triage views, an attachment center, expanded offline history, custom swipe actions, and additional themes, effects, sounds, and app icons. Purchases are handled by Apple. A Gmail account is required for live mail. People using other email apps do not need Bubble.
