Smart, focused email with AI help — for individuals and teams
Spark's Smart Inbox and Priority highlight messages from important people and bundle newsletters and notifications so the rest of your inbox stays quiet.
An AI Assistant lets you find, summarize, and take action on anything in your inbox, while an AI writing assistant drafts emails and Auto-Drafts pre-writes replies.
Translate incoming messages, get instant summaries of long threads, and quickly grasp the point without reading every line.
Share drafts, leave private comments, delegate ownership, and track progress on email threads with your colleagues.
Real-device app testing tuned for Google Play readiness
Execute your app on actual Android phones and tablets rather than emulators, so hardware-specific crashes and rendering bugs surface before release.
Automatically record screen states throughout a test session, giving reviewers visual proof of how each screen renders on different devices.
Collect logcat and system output alongside each run so engineers can trace a failure back to its root cause without reproducing it by hand.
Highlight issues that commonly trigger Play Store rejection, helping teams tidy up policy and technical problems before submission.
