What's New in Sour
1.1
August 9, 2026
See the dip before it hits you. Log what you eat and Sour estimates how your energy will rise and fall through the day, including when a crash is likely, and how deep. Scan before you buy. Point the camera at a barcode and get a straight verdict, plus what that product would do to the rest of your day. Put it back and watch the dip disappear. Your whole record, not just today. A calendar of every day since you started. Tap any day to see what was in it, the ceiling you had at the time, and the one thing that mattered most. The zero sugar challenge. Commit to 7, 14 or 30 days at zero added sugar. One slip doesn't end it — you get one repair. Six milestones on the way, each a real change your body is making, each with a date. A weekly recap that tells you what actually changed, and reminders before a crash, in the evening, and the morning a milestone lands. Streaks are gone. In their place: totals that only go up, and one challenge you choose to start.
