Substill: Subscription Tracker

How much are you really paying every month? Most people guess low — by a lot. Substill tracks every subscription and free trial you have, warns you before each charge, and shows you exactly where the money goes. And unlike the services it tracks, Substill is not a subscription: upgrade once, own it forever. PRIVATE BY DESIGN • No account. No sign-up. No cloud. • Your data never leaves your phone — we couldn't see it if we wanted to • No bank login required (and none asked for) • No ads, no tracking, ever NEVER GET SURPRISE-CHARGED AGAIN • Reminders before every renewal — you pick how many days ahead • Free-trial watch: get warned before a trial quietly turns into a paid plan • See everything due in the next 7 days at a glance KNOW WHERE THE MONEY GOES • Monthly and yearly totals, updated live • Insights: spending by category, a 12-month forecast (annual renewals show up as spikes before they hit), and your most expensive subscriptions • Mark subscriptions cancelled and watch your "money saved" grow TRACKS ANYTHING RECURRING • Weekly, monthly, quarterly, yearly, or custom cycles • 20 currencies • Streaming, software, gym, cloud storage, news, gaming — anything FREE: track up to 5 subscriptions with reminders. PRO (one-time purchase): unlimited subscriptions, Insights, CSV/JSON export. Pay once. Own it forever. That's the whole point.
