Do you really know how much your subscriptions cost you each month? Netflix, Spotify, iCloud, YouTube, apps, free trials… On their own, they seem reasonable. But over a year, the total can really sting. SubZero shows you your true monthly and yearly cost in seconds. ADD YOUR SUBSCRIPTIONS IN 2 TAPS Pick a service, enter the price and billing frequency, and SubZero automatically works out what it costs per month and per year. PAYING IN INSTALLMENTS? TRACK IT ALL A purchase split into 3, 4, 10 monthly payments? Add it as an installment plan: SubZero works out each payment, follows the schedule, and archives it on its own once it's paid off. Your real totals finally separate the temporary from the recurring. NEVER FORGET A FREE TRIAL AGAIN Started a free trial? SubZero can remind you before it turns into a paid plan, whenever you choose.

Verdict
The clearest difference is update cadence: SubZero at every 3 days against Converzy's every 3 months. Converzy's advantage is monetization model (free vs freemium) and device support (3 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.
