這是一款為「想把錢花得更安心」而生的預算管理 App。 你是不是也有過這種時候: 錢明明有存,卻不知道能不能花? 月底一到才發現,又超支了。 BajiCard 用的是信封理財法的核心精神:先分配,再花錢。 在花出去之前,就先決定每一塊錢的去向。 在這裡,你可以: ・自由建立類別與預算目標 ・把收入依「重要順序」分配給最在乎的事情 ・即時看到每個類別還剩多少,月底前還能不能花,一眼就懂 ・需要彈性時,類別間餘額可互轉,截長補短 讓你花錢花得有底氣。 許可協議:https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ 隱私權政策:https://sites.google.com/view/bajicard/首頁?authuser=0 截圖使用Median.co模板

Sonar keeps every subscription you pay for in one place: what it costs, when it renews, and what you're spending a year. Then it does something your bank statement can't. It tells you which ones you've stopped using. WHAT MAKES SONAR DIFFERENT Link a subscription to its app, and Sonar uses Screen Time to count how often you actually open it. Once a month it reports the ones you barely touched. Not an estimate: a count of the days you opened it, or didn't. EVERY SUBSCRIPTION IN ONE PLACE - Add them by hand, pick from common services already priced for your country, or import them by screenshotting your Apple subscriptions page - See what you spend per month and per year at a glance - Mixed currencies are converted using published exchange rates, covering every currency the App Store bills in NEVER BE SURPRISED BY A RENEWAL - A reminder before every renewal, as many days ahead as you like - A calendar of what is coming and what it will cost SEE WHAT YOU ACTUALLY USE - Days opened across the last 30 days, and across the last year - A monthly report naming the subscriptions you barely opened - You set the bar for what "barely used" means COUNT WHAT YOU HAVE SAVED - Cancel something and Sonar counts the charges that never happened - Totalled per year, at the price you were actually paying PRIVATE BY DESIGN Screen Time tells Sonar one thing per app per day: opened, or not. Never how long, never what you did inside it, never anything about apps you have not linked. That record stays on your iPhone. Sonar has no account, no server and no analytics. HONEST ABOUT ITS LIMITS Sonar cannot read your real App Store subscriptions, because no such interface exists on iPhone. You add them, or import them from a screenshot. It cannot cancel anything for you either. And it only sees this iPhone, so an app you mostly watch on a TV will look unused here. SONAR PRO Sonar is free for up to 2 subscriptions, with every feature. Sonar Pro removes the limit. Two ways to buy: - Yearly, with a 1-month free trial - Lifetime, one payment, no renewals Prices are shown in your own currency before you buy. Payment is charged to your Apple Account at confirmation. A yearly subscription renews automatically unless cancelled at least 24 hours before the current period ends, and you can manage or cancel it in Settings › Apple Account › Subscriptions. A free trial that is not cancelled before it ends becomes a paid subscription. Terms of Use: https://romisoft.app/terms Privacy Policy: https://romisoft.app/privacy

Verdict
The clearest difference is update cadence: BajiCard 預算卡片|記帳、預算管理、資產管理 at every 3 days against Sonar's weekly. Sonar's advantage is iOS requirement (17.0 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
