Ad Blocking That Coexists With VoWiFi And Custom DNS On Android
BlockAds blocks ads system-wide on Android using a local VPN or root proxy and reached 1,079 GitHub stars, but its top issues reveal the structural conflict of the local-VPN approach: it disconnects Wi-Fi calling because Android allows only one VPN slot, and it double-filters when users already run NextDNS. People want network-wide ad blocking that does not break calling or fight their existing DNS. The wedge is an Android blocker that coexists with VoWiFi and custom DNS instead of monopolizing the single VPN slot.
Problem Statement
An Android user enables a system-wide blocker and loses Wi-Fi calling because the blocker claims the only VPN slot, or they already pay for NextDNS and now traffic is filtered twice with conflicting logs. They are forced to choose between ad blocking and a working phone or their existing DNS, so they disable the blocker and accept the ads.
The Idea
An Android ad blocker that delivers system-wide filtering without breaking Wi-Fi calling or conflicting with a user's existing custom DNS setup.
Why Now
Mobile ad and tracker volume keeps climbing and Android users increasingly want network-level blocking in 2026, but the local-VPN method collides with VoWiFi and DNS-based blockers like NextDNS. BlockAds' traction plus its VoWiFi and NextDNS conflict issues show the coexistence problem is the real barrier to daily use.

AI Meeting Companion That Completes Follow-Up Tasks Before the Next Meeting
Meeting notes tools transcribe and summarize meetings but the action items they extract sit unfinished in a list. An AI meeting companion that not only captures action items but autonomously completes appropriate follow-ups (drafts emails, creates tickets, schedules meetings, updates CRM) before the next meeting closes the gap between meeting decisions and execution.

Memolect transcribes meetings and suggests Jira updates, but the full opportunity is a meeting-to-sprint bridge: automatically converting sprint planning, standup, and retrospective meetings into structured sprint artifacts (user stories, acceptance criteria, blockers, retro action items) that flow directly into the project management tool without manual transcription.

notigo.ai provides real-time meeting summaries. But for teams spanning 5+ time zones, real-time meetings are the problem, not the solution. A structured async meeting replacement, where participants record responses to an agenda asynchronously, AI synthesizes the inputs, identifies disagreements, and produces a decision document, would eliminate the 'who can make the 7am call' problem entirely.

Knowledge workers using AI assistants get generic outputs because the AI lacks access to their accumulated personal knowledge, bookmarks, highlights, notes, and saved research. Liminary connects personal knowledge bases to AI assistants, grounding responses in the user's own curated information.

Solo founders on Indie Hackers frequently describe capturing ideas and tasks via voice memos during commutes or walks, then losing them in a sea of audio files. A tool that transcribes voice memos, extracts actionable tasks, categorizes them by project, and pushes them to existing task managers would close the capture-to-action loop.
