Koda App
Read full descriptionHide full description
Most apps on your phone know one thing about you. Koda knows them all. Calendar, reminders, money, health, and weather gathered in one place, with optional AI that can read all of it. Ask things like "why did I sleep poorly last Tuesday?" or "show me weeks I spent more and worked out less". Today. Events, reminders, the day's weather, contact birthdays, and a money pulse on one page, laid out on a time axis that stretches around the hours where something is actually happening. Plan. Calendar and lists in one tab. Drag to reorganize, type to add. Health. Workouts with HR zones and route maps, sleep stages, a recovery score, 30-day trends. A check in records how you are feeling and saves it to Apple Health as State of Mind, so your mood sits next to the sleep and training that shaped it. Weather is event-aware. Forecasts pinned to the locations you actually have meetings at, severe-weather alerts on the day, and a "best outdoor window" scan across the next 24 hours. Built for iPhone Duo. Unfolded, Koda uses the whole canvas rather than stretching a phone layout across it. The calendar sits beside the day you picked, your accounts beside the transaction, the health summary beside the metric you tapped. The same layouts carry over to iPad. Free includes Today, Plan, Health, Weather, and manual capture. Premium adds Money, Koda (chat, briefs, and smart capture). Money. Link Apple Card, Apple Cash, and Apple Savings directly through Apple's FinanceKit, no middleman. For everything else, connect a bank through Plaid. Either way, you get month-to-date pace, recurring charges, top categories, and transactions tied to the calendar events they happened around. Koda. Daily and weekly briefs synthesize across calendar, sleep, money, weather, and workouts in plain prose. Chat answers from your own data with sources cited. Smart Capture turns plain language into the right kind of entry: type or speak "coffee with Maya Tuesday at 10, remind me to call the dentist Thursday, journal: rough day but the run helped" and each piece lands as an event, reminder, or journal note. Built on Anthropic's Claude. Privacy is local-first. Calendar, reminders, transactions, chat history, and pattern detection stay on your device. Journals, workout notes, and briefs sync between your own devices through iCloud's private database, not our servers. AI features are opt-in by category, off by default for Health, and every domain (Calendar, Money, Health, Contacts, Location, About Me, Journal) has its own switch. No ads. No tracking. We don't sell your data. Premium is $7.99 a month or $69 a year, with a 7-day free trial on annual. The in-app demo runs on sample data if you want to look around first. ****Premium is currently only available in US and Canada. Sign in with Apple. iOS 18 or later.
