"Here's how I caught $200 a year in payments I'd forgotten about" — just by spotting the subscriptions I no longer used and cancelling them. Netflix. Spotify. That cloud storage from 2019. Three services you're still paying for every month — and you've stopped using two of them. Subs Diary shows you everything you pay for, how much it adds up to, and exactly when each renewal hits — so you can cancel before the money leaves your account. 【What Changes When You See It All at Once】 • No more "wait, I'm still paying for that?" moments • You actually know your monthly subscription spend — down to the cent • You catch renewal dates before they sneak past you • You stop paying for apps you forgot you downloaded 【Everything Subscriptions, Organized】 - Subscription Tracker — Add every service: streaming, music, gaming, cloud, and more - Monthly & Annual Totals — See your real recurring spend automatically calculated - Renewal Reminders — 3-day advance notifications. Cancel before it renews. - Visual Stats — Pie charts and monthly trend graphs. See where it goes. - Category Sorting — Group by type. Spot the waste instantly. - Offline, Private — Your financial data stays on your device. People say things like: "Found $80/month I was paying for and never used. Cancelled 4 services in one day." "The 3-day warning saved me from a $200 annual charge twice." "I thought I had 5 subscriptions. The app found 11." "I tried tracking subscriptions in a spreadsheet. I kept it updated for maybe two weeks." — A spreadsheet doesn't remind you. It won't tell you a renewal is in 3 days. This app does — automatically, without you having to remember to check. "I'll just check my bank statement." — Your bank shows what already happened. This shows what's coming. "I signed up for a free trial and forgot to cancel." — Add the trial end date when you register. You'll get a reminder before the charge hits — enough time to decide if you want to keep it or cut it. "Do the reminders actually work?" — Yes. 3 days before every renewal, your phone gets a notification. No more opening your bank app and wondering why there's a new charge. "Is my financial data safe?" — Everything stays on your device. No bank connection. No login required. Your subscription list never touches a server. "Am I imagining how hard it is to cancel?" — No. In 2026, the FTC sued Uber over Uber One — 28 million subscribers signed up in one tap, while cancelling required up to 23 screens and 32 actions. That's the industry you're up against. Subs Diary is built for the opposite: see every subscription, cancel before it renews, no maze required. "My bank statement shows charges I don't even recognize — I can't tell which service they're from." — When you register a service in Subs Diary, you give it a name you'll recognize. AMZN*PRIME becomes Amazon Prime in your list. The next time a charge you can't place shows up, your registered list tells you exactly what it is. "Do I need to pay?" — Tracking subscriptions and renewal reminders are free. Premium adds more. Price shown before you commit. 【Premium Plan】 See in-app for pricing. Subscription auto-renews unless canceled 24 hours before renewal.

Verdict
The clearest difference is in-app purchases: スマートサブスクリプション at none against Subs Diary's 3. Subs Diary's advantage is device support and iOS requirement (15.0 vs 17.6). On price there is nothing between them.
