Budget, debt payoff and net worth, in one simple app

Plan your month, pick snowball or avalanche, and see your debt-free date. No account, no bank login: your numbers stay on your phone.

sigvy budget screensigvy home dashboardsigvy debt payoff screen

Everything in one place

Type in your own numbers and sigvy does the math: totals, what's left, payoff dates and progress. It opens with a sample household so you can see every screen working.

1

Monthly budget

Income, expense and savings-goal categories with budget vs actual. See what's left for the month and switch between months.

2

Quick Add

Enter an amount, tap a category, save. Log a debt payment the same way and your payoff plan updates.

3

Debt payoff

Compare snowball and avalanche side by side. See your debt-free date, the interest still to pay and a monthly payoff schedule.

4

Home dashboard

This month at a glance: income, spending, goals, debt payments and what's left over, plus year-to-date totals and a 6-month chart.

5

Net worth & FI

Monthly snapshots of assets and liabilities, your FI number, years to FI and your savings rate.

6

CSV export & import

Export your data as CSV, and import it to restore a backup or move to a new phone.

No account. No bank login. No server.

Everything you enter is stored on your phone, and manual entry means you see every number.

Prefer a spreadsheet? SlateAndSum has simple, automated money tools for Google Sheets and Excel, sold in our Etsy shop.

Every great moment has a photo of you in it.

Strobe finds the photos you're in from concerts, tournaments, festivals and events, and sends them straight to your phone.

Strovent Systems

A modern terminal for every host you still work on

We build Strovent Terminal, a multi-protocol terminal for IBM Z, IBM i, VT and SSH, on iPhone and iPad, and we design custom systems that connect core platforms to the way people work today.

Product

Strovent Terminal: IBM Z, IBM i, VT and SSH, rebuilt for iPhone and iPad

One app for the hosts you already use, designed around a hardware keyboard and touch.

  • IBM Z (TN3270 / TN3270E). TLS, LU names, models 2–5 up to 27×132, and many EBCDIC code pages.
  • IBM i (TN5250). 24×80 and 27×132, with Field Exit and the usual 5250 keys.
  • VT / ANSI and SSH. VT100/VT220 over Telnet or SSH. Sign in with a password or a key kept in the iOS Keychain. Coming in the next update: Mosh, jump hosts, local and remote port forwarding, agent forwarding, certificate and hardware-key (YubiKey) login, and a fuller xterm with 256-color, truecolor and mouse.
  • Scripts and auto-connect. Record or write scripts that wait for screen text, type and send keys — for general terminal workflows, not only logon — and run them when a session connects. Profiles can auto-connect when the app opens. Passwords are asked for each time and never stored.
  • Sessions, printing and keyboard. Keep multiple hosts open in the sessions sidebar and switch with Ctrl+Tab or Ctrl+Alt+1–9. Print Screen, and 3270 host printing, to AirPrint or PDF. Remappable hardware keys, plus tappable on-screen key labels. Built-in IBM Z and IBM i demo hosts, so you can try it offline.

IN DEVELOPMENT

Enterprise edition: 3270 access your IT team can deploy and control

A free-to-download edition that unlocks only with a company sign-in. IT manages seats, host configurations and scripts centrally.

  • Single sign-on. Microsoft Entra ID, Google Workspace, Okta, or OpenID Connect and SAML.
  • IT admin portal. Add and remove seats, push hosts and scripts, lock settings.
  • Device management. Built so MDM tools such as Intune and Jamf can push configuration.

Modernization

Modern front ends for your 3270 applications

We build web, mobile and desktop interfaces on top of the IBM 3270 systems you already run. Your COBOL, CICS and IMS applications stay exactly as they are.

  • No backend rewrite. Host programs, data and security stay unchanged.
  • Your existing security. Access still runs through RACF, ACF2 or Top Secret.
  • Incremental. Modernize one workflow at a time, starting with a pilot.

01 · Headless 3270 engine

Signs on to your host over TN3270E with TLS and drives the existing screens, exactly as a user would.

02 · Each screen becomes an API

Fields on each screen are mapped to clean, typed API calls, with host validation carried through.

03 · A modern UI on top

Web, iPhone, iPad or desktop apps built around your staff's workflow rather than the screen flow.
