What's New in Keld Wellspring

2.1.1

July 24, 2026

Keld 2.1 is the biggest release since the rebuild — and it leans hardest into training. YOUR WORKOUTS, IN FULL Every workout type now keeps its own history. Open Running, Swimming, Walking, anything you log, and scroll session by session — each row led by the stat that actually matters for that activity: distance for a run, strokes for a swim, plus time, pace, heart rate, elevation and energy. Tap any session to open it in full. Switch between This Week, This Month and All Time so a year of training collapses to the stretch you care about. GOALS Set a target for any activity and watch it fill. Your goals ride the Pulse page next to your latest workout, so the first thing you see is where you stand today. THE DATA LEDGER Every signal Keld watches now shows its own ledger — day by day, everything it has recorded. A busy signal like heart rate shows each day's average and its low-to-high range; a daily total like steps or energy shows the day's total; and a day with no data simply has no row, because Keld never invents one. Same This Week / This Month / All Time controls throughout. THE ATLAS Your signals and Elementals are now drawn as living circuit maps — one for every family, plus a World Map of everything you have built. Open any Elemental and it tells you which maps it lives on, with its emblem, and takes you straight there. THE CENSUS See how rare each of your patterns is across everyone using Keld — where yours falls in the distribution, how many others share it, and how it maps against what people find most important and most fascinating. A NEW WAY TO MOVE Navigation was rebuilt around a single wheel you can reach from anywhere in the app. Spin it, tap whatever you want — one tap, no centering, no double taps — and the labels are considerably larger and easier to read. Breadcrumbs show you exactly where you are. MORE STORIES, MORE FILMS Narrated Saga films now cover far more of the app, including your signals and the panels on your Pulse page, with synced captions you can read as they play. BACKUP YOU CAN SEE Settings now shows exactly when your Field Guide last backed up to your private iCloud, and lets you run one on the spot. NOTIFICATIONS, KEPT Every notification Keld has sent you now lives on its own page, so nothing scrolls away before you have read it. HONESTY REPAIRS A careful pass over what Keld says out loud. Sleep stages are named correctly. Signals that are measured only while you sleep no longer read as though they were watched all day. A pattern that flickers is no longer described as though it holds steady. Forecast language now defers to the measured track record behind it. When Keld does not have the evidence, it now says so instead of reaching. And the community Census now says plainly when no one has rated a pattern yet, instead of implying a few people have. Plus artwork that repairs itself when an image goes missing, search in the Metric Index, a faster Field Guide, and a long list of fixes across the app. Thank you to everyone testing Keld and sending notes. Keep them coming.
