NEW
• Spotlight: discover fresh tracks from the Trackstack community, one card at a time. Tap to play, react with an emoji, upvote or save tracks for later, and download them when the artist allows. Filter by BPM or key, sort by newest or most reacted, and tap "Less like this" (with undo) to tune your feed.
• Share your tracks on Spotlight: pick a track, add up to 10 hashtags and choose whether listeners can download it. My Tracks shows each track's downloads, reactions, saves and upvotes, and lets you change its settings or take it down anytime.
IMPROVED
• A fresh new waveform: rounded bars with a soft reflection that light up as the track plays, easier-to-read quiet passages, and a red line marking where each track starts, now in the mini player and Stack mode too.
• A smoother player: the cover and title glide up into the header as you scroll, so you always know what's playing. Tapping a notification while music is playing now opens the right track.
• Better Stack mode: like tracks right from the card, follow progress around the play button, and jump back in without the list flashing first. Liked tracks also show a filled heart in your stacks.
• A clearer Activity feed: every notification type shows properly, your full history loads on the first visit, and download and deal notifications open their details.
• Easier sending: when a track can't go to an inbox, the Send screen tells you why. Sending the same track twice shows a friendly warning instead of blocking you, the recipient list loads right away, and you can pick the inbox when sharing from a workspace with several.
FIXED
• Search on the Sent screen works again and covers your whole send history.
• The app no longer crashes on launch on iPad.
• "Remove from Playlist" only removes the track from the playlist you're in, and playlist counts are accurate.
• Paused inboxes can be unpaused from Preferences, and copied inbox links open correctly.
• Losing access to a workspace now shows a workspace switcher instead of errors.
• Plus plenty of smaller fixes and polish.
1.1.17 Oct 1
In this update:
• Discover, upgraded — Sort your inbox by For You, Most Active, Fastest Response, Trending, Newest and more, with a redesigned Sort sheet and country flags on every row. Filters always show fresh results now.
• Adjust tempo in the player — Speed a track up or slow it down without changing its pitch, right from the expanded mini-player.
• A richer mini-player — See a track's key, format, file size and review status at a glance, plus a redesigned waveform, haptic scrubbing and one-tap download.
• Request inbox verification — Ask for a verified badge on any of your inboxes, so artists know they're reaching the real you.
• More with playlists — Send every track in a playlist to your inboxes at once, or apply one cover to the whole playlist.
• Faster, sharper search — Snappier results as you type, with your recent searches remembered.
• Cleaner default artwork — Tracks without a cover now show a clean gradient instead of letter initials.
• Reliability & performance — Smoother scrolling, more dependable artwork uploads, and a batch of send/decline fixes.
