What's New in GT_O
2026.9.2
September 5, 2026
A GUIDED TOUR ON FIRST LAUNCH The app now shows you around itself. Nine steps, one control at a time: the round button, the streak, the calendar, the tab bar, the chart grid and what its colors mean, the chart builder, and your stats card. Skip it whenever you like, or run it again from Replay tutorial in Settings. REACT TO A FRIEND'S HAND Press and hold the hole cards on a head to head recap and pick an emoji. It lands on your friend's copy of that hand, with a notification to go with it. One reaction each per hand, and a bell on any friend's row turns theirs off. Settings now carries a switch for every kind of notification GT_O sends. THE WHOLE DECK, WHEN NOBODY HAS ACTED YET Open Details on a hand nobody has entered yet and the villain grid now shades all 169 starting hands, thinned only by the cards you hold. It used to draw the range they turn up with later in the hand, which is not the range you were deciding against. FIXES A capped run keeps its place when it replays its own slice. The calendar opens on today, fills in the round you just finished, and names each day's spot the way the round itself does. On the free tier, the hand grid inside a round draws the hands your tier plays, instead of twenty with most of them blank. A past day reads back the same on the way in as on the way out: the date, the cost of every hand, and the by street breakdown. The opponent you race is offered on the screen a replay ends on, not only the one it starts from, and never turns up on a round you are still playing. A day too old for the app to still hold your own round says so, instead of offering a race with nobody in it. An invite code a friend redeemed straight in the App Store can be replaced now, and a replacement the server turns down says why. A starred friend is called a favorite everywhere, and the star comes off from the comparison screen too. The hand grid stays on the screen at the largest text sizes.
