Stop wasting money on forgotten subscriptions. The average person spends over $200/month on subscriptions — and most don't realize it. That free trial you forgot to cancel? Still charging you. That streaming service you watched once? Still running. SubTrackr reveals your real subscription spending in seconds and helps you take back control. ———————————————— HOW MUCH ARE YOU REALLY SPENDING? Most people guess they spend around $80/month on subscriptions. The real number? Usually 2-3x higher. SubTrackr scans your App Store subscriptions automatically, then helps you add everything else — streaming, music, cloud storage, gym memberships, news, productivity tools, and more. Within minutes, you'll see the full picture for the first time. ———————————————— AUTOMATIC APP STORE DETECTION SubTrackr connects with your App Store account to instantly find every active subscription — including ones you forgot about. No bank connection needed, no passwords shared, no personal data collected. Just a clear list of what Apple is charging you. ———————————————— 250+ POPULAR SERVICES, ONE TAP TO ADD Adding subscriptions outside the App Store is fast. Choose from our catalog of 250+ popular services — Netflix, Spotify, YouTube Premium, Disney+, Adobe, Notion, gym chains, news outlets, and more — complete with official logos and preset pricing. Or create custom entries for any recurring payment: rent, insurance, internet, phone bill, or anything else you pay regularly. ———————————————— SMART RENEWAL REMINDERS Never get surprised by an unexpected charge again. SubTrackr sends you a notification before every renewal — choose 3 days before, 1 day before, or on the day. You decide when and how you want to be reminded. Enough time to cancel what you don't need, keep what you love. ———————————————— YOUR SPENDING DASHBOARD See your total subscription cost per week, month, and year — updated in real time. Watch spending trends over the past 6 months with clear, visual charts. Break down costs by category: entertainment, productivity, health & fitness, news, cloud & storage, music, and more. Finally understand where every dollar goes. ———————————————— FIND SUBSCRIPTIONS YOU DON'T USE SubTrackr highlights subscriptions that might be costing you money for nothing. See which services you haven't opened in weeks and get a clear savings estimate: "Cancel these 3 subscriptions and save $37/month." The decision is always yours — we just make sure you see it. ———————————————— PRICE CHANGE ALERTS Subscription prices go up all the time — often without you noticing. SubTrackr tracks your pricing history and alerts you when a service increases its price. Know exactly when Netflix went from $13.99 to $15.49 and decide if it's still worth it. ———————————————— PRIVACY FIRST — NO BANK CONNECTION Unlike other subscription managers that require linking your bank account, SubTrackr keeps everything on your device. No bank credentials, no financial data shared with third parties, no account creation required. Your subscription data syncs privately via iCloud across your devices — and nowhere else. ———————————————— BEAUTIFUL WIDGETS Add SubTrackr to your Home Screen with widgets that show upcoming renewals and your monthly total at a glance. Small widget: next renewal date and amount. Medium widget: upcoming renewals list and monthly spending. No need to open the app — your subscription overview is always visible. ———————————————— DESIGNED FOR EVERYONE Whether you have 5 subscriptions or 50, SubTrackr scales with you. Multi-currency support with automatic exchange rates for international subscriptions. Clean, intuitive interface that takes 30 seconds to learn. Full dark mode. Full iCloud sync. No ads — ever. ———————————————— Terms:https://subscription.sourcesoftware.net/terms.html
