How Ember works
Plans & billing
Ember has three plans. There are no ads on any plan, ever — the free plan is a genuinely usable FIRE tracker, not a stripped-down demo.

Spark's entity limits
Spark is capped per entity type rather than by a time limit or a locked feature — you can hold a real, if modest, balance sheet for free. The cap only ever blocks adding a new row past the limit; it never touches data you've already entered, so dropping back to Spark never deletes anything. Ember and Blaze are uncapped.
| Entity | Spark limit |
|---|---|
| Investments | 10 |
| Debts | 5 |
| Pensions | 3 |
| Properties | 2 |
| Planned events | 5 |
The 72-hour full-access trial
Every new account gets a 72-hour boost to full Ember-level access — every feature except report downloads and Google Sheets export, which stay gated to a real paid tier so the boost can't be used to churn through exports. When the boost ends, a plan-choice screen asks you to pick Spark, Ember, or Blaze; your account never locks, and if you do nothing it simply settles onto the free Spark plan. During the boost you also get a small taste of hosted AI — enough to try chat and insights, well short of a full paid allowance (see AI features).
Monthly vs annual billing
Ember and Blaze can be billed monthly or annually. Annual billing is 15% cheaper than paying monthly for a year — Ember works out at $152.90/yr and Blaze at $305.90/yr, billed once a year instead of $14.99/mo / $29.99/mo each month. You can switch cadence, upgrade, downgrade, or cancel at any time from Settings → Account, where the exact prorated amount is always shown before you confirm anything.
Promotional codes may be available from time to time — any code you have is applied at checkout and the discount it gives is shown before you pay.
AI credits are separate from your plan
AI chat and insights draw on a monthly allowance that comes with Ember and Blaze, plus an optional one-off credit top-up available on any plan. See AI features for how metering, advisory mode, and cost caps work.
Connecting accounts
Broker/crypto sync needs Ember; bank sync is planned for Blaze. See Connections & import for the full picture, including CSV import (works on every plan).
