Are you really getting value from all your subscriptions? Subport turns each subscription into an adorable character ("student") that you rate with regular "report cards." When a service isn't pulling its weight, you'll know — and your avatar will tell you too. ► Report Card Ratings Evaluate each service on four criteria: how often you use it, how satisfied you are, whether you'd continue, and whether you'd recommend it. Your avatar's expression reflects the score in real time — happy for high scorers, worried for ones falling short. ► Candidate System Thinking about a new subscription? Add it as a "candidate" first. When you're ready to commit, enroll it. Stop impulse subscriptions before they start. ► Cost Breakdown Tap your monthly or yearly total to see a visual breakdown of what each service costs as a percentage of your budget. Know exactly where your money goes at a glance. ► Score Trend Chart See how your satisfaction with each service changes over time. Spot the ones gradually losing value before the next renewal catches you off guard. ► Smart Notifications Get notified at the right moments: 10 and 20 days in for monthly plans, monthly check-ins for yearly plans, and 3 days before renewal for both. Multiple alerts on the same day are bundled into one. ► Multi-Currency Support Supports JPY, USD, EUR, and GBP. Everything is automatically converted and totaled in your preferred display currency. ► iPhone, iPad & Mac Your data syncs automatically via iCloud across all your Apple devices. ► Plans - Free: Manage up to 10 subscriptions - Premium Monthly (500 yen/mo): Up to 100 subscriptions + all features - Premium Yearly (4,500 yen/yr): Up to 100 subscriptions + all features (save ~25%) Premium is eligible for Family Sharing with the same Apple ID.
