Is there an app to track business SaaS subscriptions?

We’ve done some research into modern ways to track ongoing subscription payments for software and three choices to reseaerch further are:

• Cardlife (apply for a business mastercard that links to the app). Pricing starts at $49 per month
• Bobby 2 (download iOS app for free and pay for in-app upgrades)
• Truebill (an app that connects to major subscription services and will cancel free trials, obtain refunds and more)
