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 in-app purchases: Smart Spend at none against Sonar's 2. Sonar's advantage is ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
