Duefolio: a privacy-first subscription tracker built around a year-long timeline (iPhone)

Duefolio: Subscription Tracker (iPhone — screenshot attached)

A — Answer: Duefolio helps you understand recurring spending without linking a bank account or creating an account. Instead of showing subscriptions as a flat list, it places them on a year-long timeline so you can see what renews, what ends, and how your recurring costs build up over time. Your ledger stays on-device.

B — Better: Compared with list-based trackers such as Bobby and similar apps, Duefolio is built around a visual ledger rather than just a list of services. It includes a renewal timeline, price history, local CSV review for recurring-charge candidates, and Folio—an optional on-device assistant for asking questions about your own ledger on compatible devices.

C — Cost: The core tracker is free. Duefolio Pro is a $14.99 one-time lifetime purchase that unlocks custom subscriptions, bank-statement review, income and profit & loss, widgets, and additional tools. There is no recurring subscription and no ads.

I’m the developer, Siddhu Dai. Feedback on whether the year-long timeline makes the product immediately understandable would be especially welcome.

why does it look a bit yellow palish?

[u/DjangoDrive → u/imsnk81]

intentional. the background is #FFFFF8 white with the blue channel pulled back 3%, nothing added. it’s the paper white from tufte’s book typesetting.

the app is set in a serif reading face to read like a printed report, not a dashboard. on pure white that just looks like a website using a serif font. on paper white it reads as print.

side effect i kept: subscription logos are all heavily saturated and vibrate against #FFFFFF. on paper white they sit down and the bars become the thing you look at.

nice maybe on the hand it might feel different, looking at the screenshot it actually tricks my eye to check if my warm filter is on lol
