Safe-to-spend is shaped by the obligations coming next, not just the cash sitting in checking.
The safe-to-spend answer, rebuilt outside the bank.
Simple made one idea feel obvious: your balance is not what you can spend. Catalyst Cash brings that answer back as a local-first iPhone app that works with manual entry or optional Plaid.
The search behind this page
Simple users did not just lose a bank. They lost an interface for calm.
Former Simple customers still describe Goals and Safe-to-Spend as the feature that made money feel understandable. The gap is not nostalgia. It is the missing daily answer: after bills, goals, renewals, and pressure, what is actually safe?
Honest comparison
Simple was a bank with budgeting built in. Catalyst is the budgeting brain you can use with your current accounts.
| Question | Simple-style banking apps | Catalyst Cash |
|---|---|---|
| What Simple did well | Goals, Expenses, and a Safe-to-Spend balance that subtracted money set aside for future needs. | Daily safe-to-spend, bills, renewals, budgets, ledger, card rewards, debt context, weekly audits, and Ask AI. |
| Account model | Simple was tied to the bank account itself and shut down with the banking product. | Catalyst is independent of your bank. Type entries manually or link supported accounts through Plaid when you want freshness. |
| Beyond safe-to-spend | Simple focused on the checking-account experience. | Catalyst adds credit cards, rewards, debt, net worth, subscriptions, backup, and weekly action planning. |
| Tradeoff | A bank-owned system could move money automatically inside the account. | Catalyst does not move your money. It gives the decision layer and keeps account control with you. |
Where Catalyst is different
The same calm answer, with more of your financial life included.
You do not have to switch banks to regain the safe-to-spend habit.
The weekly audit shows what changed and which move deserves attention next.
Trust boundary
Local-first means the replacement is not owned by a bank shutdown.
Catalyst Cash keeps manual entry first-class, makes Plaid optional, stores the working record locally by default, and uses deterministic money math before AI explanation. It does not store bank usernames or passwords, sell spending data, or charge a cut of your savings.
- ConcessionCatalyst is not a bank and does not recreate automatic in-account goal transfers.
- DurabilityYour working record lives locally by default, with encrypted backup and Recovery Vault options.
- ControlManual entry stays complete, so you are not blocked when a bank connection fails.
