Hi Product Hunt 👋 I'm Bin Tech, the solo developer behind SubFlow.

It started with a question I couldn't answer: how much do my subscriptions actually cost me each month? The popular trackers all wanted me to link my bank account — and I wasn't about to hand my banking login to an app just to count my Netflixes. So I built the tracker I wanted instead.

SubFlow is manual on purpose:

🔒 No bank login, no account to create — your subscription list stays on your own device

⏰ Renewal reminders 1, 3 or 7 days ahead, plus free-trial countdowns so a trial never quietly turns into a charge

💱 40 currencies at live exchange rates, so your € and $ subscriptions add up to one honest monthly total

📊 Spending analytics, a home-screen widget, JSON backup, and 10 languages

It's free for up to 5 subscriptions (with ads). Pro removes the limits and ads and unlocks the full analytics — monthly, yearly with a 7-day free trial, or a one-time lifetime purchase. (A subscription tracker that only sold subscriptions felt a bit ironic.)

Three things I'd genuinely love your take on:

1. Which services should I add to the built-in catalogue next? (34 are in already)

2. Is your currency or language missing?

3. What would make you trust — or distrust — a finance app that never touches your bank?

I'll be here all day replying to everyone. Thanks for stopping by 🙏
