SavingMan helps individuals and families manage term deposits, CDs, and Treasury securities from deposit and interest payments through maturity, withdrawal, or renewal. • Complete records: Keep principal, currency, bank, rate or APY, term, deposit and maturity dates, interest schedule, family member, and notes together, with exact large-amount display. • Maturity and interest reminders: Track interest paid at maturity, monthly, quarterly, semiannually, or annually. Control interest reminders separately, then snooze a notification or open the matching record. • Clear earnings: Review estimated interest and the next 12 months of principal and interest cash flow. Optional interest-tax estimates separate pre-tax interest, estimated tax, and after-tax interest. Multi-currency summaries can use ECB reference rates. • Guided withdrawal and renewal: Preview an early or maturity withdrawal before saving it, handle full or partial amounts, and confirm new dates, terms, rates, and interest schedules when the bank changes renewal terms. • Traceable and correctable: Review all disposition history, the contract before each action, and the renewed contract. The latest eligible action can be undone safely inside the app. • Private and recoverable: Core data stays on your device. On Apple platforms, private iCloud sync keeps iPhone and Mac records aligned. Complete JSON backup is free. The macOS app adds a desktop sidebar, search, keyboard workflows, and light or dark appearance. SavingMan Pro unlocks unlimited records, CSV import/export, iCloud, calendar tools, the full Earnings Center, interest-tax estimates, and a separate earnings window. SavingMan does not connect to bank accounts or execute deposits, withdrawals, or investments. Interest, tax, exchange-rate, and withdrawal results are estimates based on your entries; confirm final amounts with the bank, issuer, and applicable local rules.

Verdict
The clearest difference is ads: SavingMan at none against Interest Meter's shown. SavingMan also leads on device support (4 vs 2). Interest Meter's advantage is update cadence (every 3 days vs weekly). On price, in-app purchases and iOS requirement there is nothing between them.
