Avid Expenses

Some spending doesn't fit into a monthly budget, it happens in bursts. A weekend tournament. A two-week trip. A kitchen renovation that's somehow still going. Avid is built for exactly that: a fast, uncluttered way to track spending around whatever you're actually doing, without dragging in everything else in your financial life. ONE CONTAINER, HOWEVER YOU'RE USING IT Give it a name, a date range, and a color, and Avid gives you a running total that updates the moment you log something. Call it a trip, a project, or just "March." It works the same way for travel, an event, or a job you're partway through. BUILT FOR THE MOMENT YOU'RE SPENDING Tap the + button, drop in an expense, and fill in the name, amount, and category right there. It's designed around the one moment that matters most — right after you've paid for something — so nothing gets lost or forgotten by the time you'd get around to writing it down later. SEE WHERE IT ACTUALLY WENT Flip the Sorted view to regroup your expenses by date or by category, so you can see the story of your spending however makes sense to you whether day by day, or category by category. A LITTLE COLOR FOR EVERY TRIP Each trip gets its own soft, warm color theme — ten to choose from tuned for light and dark mode alike — that carries through its header, its total, and its cards. It's a small touch, but it makes flipping between a work project and a weekend trip feel like flipping between two different rooms, not two spreadsheets. READY TO GO, CATEGORIES INCLUDED Meals, flights, cars, and lodging are set up from the start, and you can rename or add your own anytime in Settings. WORKS OFFLINE, CATCHES UP LATER No signal at the trailhead or thirty thousand feet? Log away. Avid keeps working offline and syncs quietly across your devices once you're back online. RIGHT AT HOME ON ANY SCREEN Built to fit an iPhone SE without feeling cramped, and just as sharp stretched across a full iPad. A SMALL WAY TO DO GOOD 10% of every Avid subscription goes to A21, an organization working to end human trafficking. Try Avid free for 3 days, then continue for a subscription that gives back. Avid Expense Tracker is available for a Basic monthly ($.99) or yearly ($12.99) subscription that supports continued improvements and new features. Both offer a free trial to give you time to get to know Avid and decide if it works for you.
