Piggy Notes is a minimalist personal expense tracker built around one idea: log fast, see clearly. No complex reports, no fiddly setup — open it and start. Note: the app interface is in Simplified Chinese. LOG IN SECONDS Tap the coin button, pick a category, type the amount — done. A built-in calculator keypad lets you add up a bill on the spot (e.g. 50+20). You can also hold to speak (Beta, Mandarin only) and let the app fill in the amount, category and date for you. SEE YOUR MONTH AT A GLANCE The home ledger groups every entry by day, with income in green and spending in red, and monthly totals pinned on top. Swipe back through previous months anytime. UNDERSTAND YOUR YEAR Yearly charts show month-by-month income vs. spending, your net cash-flow trend, and this year versus last year — so you can see where the money goes. AUTOMATE RECURRING ENTRIES Rent, subscriptions, memberships, salary — set a rule once (daily / weekly / monthly / yearly) and it posts automatically when due. MULTIPLE CURRENCIES CNY, USD, JPY, EUR, GBP and HKD. Each entry keeps its original currency and is converted to your base currency for summaries, with on-demand exchange-rate updates. PRIVATE BY DESIGN All data lives in your own private iCloud and syncs across your devices automatically. There is no server — we don't collect, upload or analyze your data, and there are no ads or third-party tracking. FREE Every feature is free. No in-app purchases, no subscriptions, no ads. iCloud sync requires signing in to iCloud on the device; cross-device sync uses the same Apple Account.

A softer light for the middle of the night. When your iPhone flashlight is more than you need, Night Light turns your screen into a calm, gentle light. Open the app and your saved color and brightness are ready. No account, setup, or clutter. MAKE IT YOURS Choose warm amber, warm white, deep red, candle, green, or moonlight. Pick any custom color and adjust the screen brightness from 1% to 50%. Night Light remembers your favorite settings for next time. Deep red and warm amber are gentle choices for checking on a sleeping child or finding your way without waking anyone. OPEN IT YOUR WAY Add the circular widget to your Lock Screen or Home Screen to open your saved light with one tap. On iOS 18 and later, you can also add Night Light to Control Center, a Lock Screen control, or the Action button on supported iPhones. Normal iPhone authentication may still be required. OPTIONAL REAR LIGHT Need a little more? One tap turns on the rear flashlight at a deliberately low level. It never turns on automatically, and it switches off when Night Light leaves the foreground. SIMPLE BY DESIGN Night Light opens directly into your favorite preset, uses a dark launch screen, and keeps controls minimal and easy to find. FREE AND PRIVATE Night Light is completely free, with no ads, accounts, subscriptions, analytics, or tracking. Your settings remain on your device. Optional tips unlock nothing—the full app is available to everyone.
