Your brokerage app shows your balance. It never shows the distance — when you'll actually be free. Apogee turns every purchase into what it really costs: days of financial freedom. Before you buy. No bank linking. No account. No ads. Everything stays on your device. ◆ Sound familiar? · Your balance grows, but "how far to my goal" stays a mystery · The goal feels so far away that saving loses its meaning · Impulse buys quietly eat what you meant to save · Budgeting apps died after two weeks of manual entry ◆ What Apogee does 1) Your Apogee — the date you become free Enter net worth, monthly investing, expected return, and your target (about 60 seconds). "Your Apogee: March 2044." Your goal becomes a date, not an abstract number. Set the target directly, or estimate it as yearly expenses × 25 (the 4% rule of thumb). 2) See the real price tag Add anything you're tempted by — name and price. Apogee instantly translates: "That $200 = your freedom moves 12 days away." You can still buy it. Apogee never blocks you. It just shows you the distance. 3) Sleep on it — 48 hours Cool each temptation for 48 hours (or 7 days). When time's up, one quiet notification: "Still want it?" Behavioral research suggests most impulses fade after a few days. If you still want it — buy it proudly. That's not an impulse anymore. That's a choice. 4) Every resist banks days Choose "resisted" and your freedom date moves closer: +12 days, banked. Streaks, monthly gains, all-time totals, milestones — saving stops being deprivation and becomes a game of pulling your future closer. Bought it anyway? No guilt. Tomorrow you bank days again. 5) Home Screen widget (Pro) Your countdown and this month's banked days — visible without opening the app. ◆ Privacy is the feature · No bank linking — your accounts stay yours · No sign-up, no email · All data lives on your device. Nothing is sent to a server · No ads, no tracking ◆ Pricing Free: the full loop for up to 3 temptations, plus your countdown meter. Pro: unlimited temptations, Home Screen widget, CSV export, full streak history. Yearly (7-day free trial), monthly, or a one-time lifetime purchase. ◆ Made for you if… · You're on the path to FIRE, Coast FIRE, or Barista FIRE · You want fewer impulse buys without tracking every coffee · Budget apps never stuck — Apogee only cares about the big purchases · You want your savings motivation to survive the years the market goes sideways ◆ Note Apogee's projections are general simulations based on your inputs — not investment advice, and not a guarantee of future results.

Verdict
The clearest difference is ads: Apogee at none against Graph Compound Interest's shown. Graph Compound Interest's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 16.4). On price, update cadence and in-app purchases there is nothing between them.
