Know in seconds if a stock looks cheap, hot or risky — no finance degree needed. DCAvg = Dollar-Cost Averaging, made ridiculously simple. Buying a little at a time, instead of all at once, is one of the smartest habits in investing. DCAvg shows you when those moments come. Think of it as a smart friend in your pocket — minus the jargon. Fully built in 繁體中文, 简体中文, 日本語, 한국어, Español, Português, Français, Italiano and Nederlands — not just translated, made for you. DCAVG'S AI DOES THE HOMEWORK • Tap any stock: DCAvg's AI reads over a dozen live numbers — price, trend signals, volume, 52-week range, upcoming earnings — and sums it all up in plain words. Nothing to type, nothing to look up • A traffic-light gauge on every pick: green = good setup, red = be careful • Share any verdict as a good-looking image card • Company profiles in your language — read out loud if you prefer YOUR STOCKS, RIGHT ON YOUR HOME SCREEN • Watchlist widget, live all day: prices update on their own, from pre-market to after hours — even when DCAvg is closed • Lock Screen widgets: is the market open? A live countdown to the next bell, plus your daily Market Karma • Closing prices show up by themselves, seconds after the bell PRO SIGNALS, IN PLAIN ENGLISH • The tools pro traders use (RSI, ATR and more), shown as simple arrows, dots and colors • A report card for every stock, A (strong) to F (weak). Just read the color • An alert when a stock moves more today than it usually does — never get blindsided • A little red dot when a stock you own drops into a good buying zone — your "maybe add more" moment SEE YOUR MONEY CLEARLY • Bubble chart: winners and losers at a glance. Big bubble = big impact • Cheap or expensive right now? One bar shows where today's price sits in its 1-year range • DOW, NASDAQ, S&P 500 and markets around the world, each with a simple Open/Closed light • Sold some shares? Check them off and see instantly if you've broken even • "What if I'd bought at $50?" Long-press any stock and try any price NEVER GET SURPRISED • Earnings dates, dividends and the NYSE holiday calendar — all in one place • Fear & Greed mood ring: is everyone panicking (often bargains) or partying (often a time for caution)? • Interest rates and other big-picture numbers, made simple EASY FROM DAY ONE • Add a trade by just saying it: "INTC 50 shares at 109.40" • Search that gets you: typos are fine, and words like "cheap" or "rising" find what you mean • Pocket Guide: ask how anything in the app works, in your language • iCloud backup, daily and automatic — switch phones without losing a thing A LITTLE FUN, TOO • Market Karma: your daily "good day to trade?" rating, based on your Chinese zodiac • Quick prices for gold, silver and copper • Fresh motivation, right when you need it PAY ONCE.

Sinkstack

Sinkstack turns irregular bills into a plan for every paycheck. Create a sinking fund for each bill you only see a few times a year, such as car insurance, holidays, renewals and repairs, and Sinkstack shows what to set aside from each upcoming paycheck so each one is covered by its due date. NEW IN 4.0: PAYCHECK PLAN Choose how often you are paid and one payday. Each of your next 4, 6 or 12 paychecks then lists what to set aside for every fund: • Funds with a due date spread what they still need evenly across the paydays before that date, exact to the cent. • Recurring bills start their next cycle automatically after each due date. • Funds without a due date use the contribution you planned. • Bills that land before your next payday are flagged with the amount still needed. • Enter your take-home pay (optional) to see what is left after the set-asides. • Book the next paycheck's set-asides as deposits in one step, or export the plan as CSV. ALSO NEW • Backup & Restore: one file with every fund, ledger entry, pay schedule and Payday Bridge plan. Restore checks the whole file first and saves a copy of your current data before replacing anything. • Widgets: a Next Payday countdown (you set the schedule in the widget; it never shows balances) and Quick Actions for the allocator, Paycheck Plan and Payday Bridge. • Control Center control and Siri / Shortcuts actions to open the allocator, Paycheck Plan or Payday Bridge. • A redesigned tab layout: Funds, Paychecks, Calendar, Insights and Settings. EVERYTHING ELSE YOU ALREADY HAVE • Unlimited sinking funds with goals, due dates, weekly to annual contributions, revolving funds and recurring bills that reset after each due date. • Paycheck allocator: split new money across your funds proportionally, by priority or evenly, booked as dated deposits. • Payday Bridge: put income and payments on real dates to find the lowest balance before payday and test a late payday. • Funding Calendar: 12 months of set-asides and bill dates, with busy months marked. • Insights, catch-up options for funds that fell behind, a what-if solver, PDF statements and CSV export. • 60+ templates for common irregular expenses. PRIVATE BY DESIGN No account, no bank login, no ads, no tracking. Your data stays on your device. Amounts use exact decimal math. One purchase. No subscription. Sinkstack is a planning tool. It does the arithmetic on the numbers you enter; it does not move money, connect to a bank or give financial advice. iPhone and iPad.
