What's New in Keld Wellspring
2.1.5
August 4, 2026
STORAGE AND SYNC - If your iCloud storage is full, Keld now tells you plainly instead of promising a retry that cannot happen, and reminds you once a day until there is room. - Sync can now be turned off, and stays off. IPAD - Spoken readings and films no longer lose their opening words. Every beat now starts on its first word, with no tone in front of it. - Swiping in from the left edge to go back works after you rotate the iPad, in both orientations, and after any number of rotations. ACCURACY AND CLARITY - Your data ledger now groups entries by your own day rather than by UTC, so a late-evening reading lands on the day you had it. - Setup no longer implies Keld needs an Apple Watch. Keld reads whatever already writes into Apple Health, and now says so, along with a clearer explanation of how your devices stay in step. RELIABILITY - A small number of people have had Keld freeze on them. Keld now records which screen you were on when something goes wrong, so we can find the cause instead of guessing. It records a screen name and nothing else.
