How does SubTrim help me save money on subscriptions?

SubTrim runs a usage audit on each subscription, asking how often you use it, your satisfaction, and whether you'd miss it. Based on your answers, it gives keep, cancel, or downgrade recommendations and calculates your potential savings.

Can SubTrim find overlapping subscriptions?

Yes. SubTrim detects when two or more of your subscriptions serve the same purpose (e.g., multiple music streaming services) and flags them during your audit so you can decide which to keep.

Yes, SubTrim is completely free. Track unlimited subscriptions, run audits, view deals, and export your data at no cost.
