Stop unwanted renewals before they happen.
Flowarden is a preventative financial control layer over your recurring spend. Virtual trial cards, Auto-Pilot rules, and a calendar-first view of every renewal — so money leaves your account only with your consent.
Not a tracker. A control layer.
Flowarden sits between your bank and every merchant, giving you veto power over every recurring charge.
AI Detection
Auto-detects every recurring charge across accounts — even poorly labeled ones — and predicts next renewal with confidence scoring.
Timeline Calendar
See every renewal before it hits. Color-coded by risk. Sync to Google, Apple, or any ICS-compatible calendar.
Trial Shield
Generate Luhn-valid test card numbers in seconds. Sign up for free trials with a number that passes form validation but can't be charged.
Auto-Pilot Rules
Your money, your rules. Auto-cancel anything over $100/yr. Require approval above $25. Downgrade unused services.
Block Before Charged
Unwanted renewals get declined automatically. You review, approve, or reject — BEFORE the charge posts.
Subscription Creep Alerts
Track cost-per-use, duplicate services, and silent price hikes. Stop bleeding money on things you don't use.

Subscriptions are designed to leak.
The average household runs 42 subscriptions and quietly forgets about a third of them. Trials roll into renewals. Prices creep up 3× before anyone notices. Cancel buttons hide three menus deep.
Flowarden installs a control room between your bank and the merchants. We see the full picture, predict what's coming, and intervene before the charge clears.
Read the architectureThree steps. Zero unwanted charges.
Detect
Connect your accounts or manually add — AI maps every recurring charge across banks, apps, and email receipts.
Shield
Register the virtual cards you create with your existing provider. For existing subs, set Auto-Pilot rules.
Approve
Renewals notify you in advance. Approve with a tap, or ignore to let Auto-Pilot decline automatically.
A wall between you and the renewal.
Generate Luhn-valid test card numbers and use them to sign up for free trials. The numbers pass form validation but aren't backed by any account — so the trial physically cannot auto-renew on your real card.

People who took their money back.
"The AI insights flagged three services I was paying for twice under different names. I would never have caught that myself."
"I showed my team Flowarden at standup and half of them signed up the same day. The leaderboard became our office pastime."
"The calendar view is the feature I didn't know I needed. Seeing every renewal laid out before it hits is the adult version of setting phone alarms."
"The Concierge team negotiated a 35% discount on our Adobe seat licenses before I even finished my morning coffee. Uncanny."
"Trial Shield is the simplest thing in the app and it pays for itself. Every 'free' trial I sign up for now uses a Flowarden number — zero conversions I didn't want."
"I had 23 subscriptions I'd forgotten about. Flowarden found 17 of them in 3 minutes and got rid of 9. Felt like a tax refund."
