Stop Overspending
Read full descriptionHide full description
"Where did all my money go this month?" Payday feels great. But then you grab one more thing at the store, small purchases pile up, and by month-end you're scraping by. You just can't seem to stop the money from slipping away. Toriwake is built to stop overspending — not to make you log receipts, but to keep you from spending too much in the first place. ■ Always know what's left to spend At the start of the month, you divide your income across your spending categories. Then "How much can I spend today?" is always one glance away. Your balance drops in real time as you spend, so you catch yourself at the register — "maybe not today." When the limit is visible before you spend, you can enjoy what's left, guilt-free. ■ It never scolds you Go over your limit and there's no angry red alert. Just a calm note: "this one's running low a little early." Because it doesn't blame you, opening the app never feels bad — so you keep going. Overspending becomes a discovery for next month, not a failure. ■ Logging takes seconds Enter an amount, pick a category. That's it. Snap a receipt or screenshot and the amount and store fill in automatically. Choosing which category to spend from — that one small tap — is what puts the brakes on overspending. ■ Subscriptions, all in one place Pick from 466 major services and the monthly charge is added for you. See when and how much you'll be billed on a monthly calendar. Cancellation reminders help you avoid forgetting to quit before a free trial ends. ■ It learns your spending habits After a few months, the app learns your patterns. It gently nudges you when you forget to log, and adds a short reflection at month-end. On Apple Intelligence devices, that reflection is generated by on-device AI. ■ Your money never leaves your device The amounts, categories, and receipt photos you enter are never sent off your device. No account, no bank connection. Everything works offline. ■ Home Screen widgets - Four widgets: Left Today / Left This Month / Subscription bills / Quick entry - Customize background, accent, and text color - Lock Screen widgets supported This app is for you if you: - Tend to overspend without meaning to - Feel flush on payday but broke by month-end - Can't recall where all the small purchases went - Can't say how many subscriptions you're paying for - Don't want to be scolded for overspending - Are wary of bank connections and data sharing Start by simply dividing up this month's money. Set your limits before you spend, and the money stops slipping away. This app helps you curb overspending and does not provide investment or financial advice. ——— Terms of Use (EULA): https://toriwake.askwhite.jp/en/terms.html Privacy Policy: https://toriwake.askwhite.jp/en/privacy.html
Sonar

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
