Subscriptions.ink is a modern subscription tracking app designed to help users manage and monitor their recurring expenses in one simple, organized place. Users can add their subscriptions, track billing cycles, view upcoming payments, and get a clear overview of how much they spend on recurring services.

The project focuses on simplicity, clean design, and an intuitive user experience rather than trying to become a full-scale personal finance platform. It provides an easy way to answer questions like “What subscriptions am I paying for?”, “When will I be charged next?”, and “How much am I spending every month?”

Built as a focused SaaS/product project, Subscriptions.ink explores subscription management, recurring-payment tracking, dashboard design, and building a polished consumer-facing web application.

Questions & Answers

As answered by people managing Options Backtesting Engine and Subscriptions.ink.

Which are the primary technologies used for building your product?

Subscriptions.ink's answer:

Frontend: React, Vite, and Tailwind CSS Backend: Nodejs, Cloudflare, and Polar.sh

What makes your product unique?

Subscriptions.ink's answer:

Honest, manual subscription tracking with real alerting — explicitly positioned against fabricated "auto-detection" and invented social proof. The differentiator is clarity and control: you enter your own data, it syncs to your account, and you can export or delete it anytime. Standout features: per-subscription price history with price-increase alerts, a "graveyard" archive that tallies money escaped from canceled subs, budget tracking, billing calendar, spending analytics, and 7-currency display.

Why should a person choose your product over its competitors?

Subscriptions.ink's answer:

  • Says only what the product does — no invented capabilities, metrics, or testimonials
  • User owns the data: export/import/reset/delete are first-class
  • Price-increase alerts come from real saved price history, not guesses
  • Professional "ledger" design (warm paper, one red accent) — deliberately anti-"AI slop"
  • Free to start, no credit card required

How would you describe the primary audience of your product?

Subscriptions.ink's answer:

Individuals paying for several digital subscriptions — streaming, music, cloud storage, software, AI tools — who want one honest view of monthly spend and when bills come due. (Inferred from copy and features; not confirmed with real user research.)
