How did today feel? That's the only question Vesper ever asks. No streaks to protect. No scores to chase. No guilt for the days you miss. Vesper doesn’t gamify your feelings or compete for your attention, it asks once each evening, then gets out of your way. What’s left, over time, is an honest, quiet record of your life worth actually looking back on. WHAT VESPER DOES Every evening, Vesper asks how today felt: Good, Meh or Hard. Add a line if you want to remember why. Your answer becomes one colored dot on a simple monthly grid. Miss a day and nothing happens, no penalty, no broken chain to mourn. Vesper never judges your day. It just holds it. Tap any past day to see what you wrote. Once you’ve kept it up for six months, your memory trail unlocks: every note you’ve ever written, in one place, in your own words. VESPER PLUS For anyone who wants to see the bigger picture, Vesper Plus reveals patterns that only show up over time: - Side by Side, comparing recent months at a glance - Shape of Your Weeks, seeing which days tend to feel harder - Quietest & Fullest, the months that stood apart - Yearly Portrait, one full year, at a glance - On This Day, a quiet echo of what today looked like a month or a year ago Plus also includes: - iCloud sync, so your record follows you across every device - An Apple Watch app, for checking in from your wrist - A home screen widget, a glance at your month without opening the app - Curated themes: Chalk, Marigold, and Ink - Anytime check-in, if evenings aren't when your day actually ends Vesper Plus is available as a monthly or annual subscription, or a one-time lifetime purchase. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ YOUR DATA STAYS YOURS Vesper syncs privately through your own iCloud account. Nothing is shared, sold, or used to train anything. Some days are good. Some are hard. Most are somewhere in between. Vesper is a quiet place to keep track of all of them.
