Calendar, mail, memo, tasks — one app, one account.

What it does

The things STA saves time on, every day.

One app, four tools

Calendar, mail, memo, and tasks live in one screen. No more switching apps.

AI assist

Say "meeting tomorrow at 3" and it lands on the right tab — events, tasks, or memos. Unified search understands natural language too.

Cross-tab automation

Mail → event, memo → task, event → meeting notes. One tap follows the seam.

Multi-account + two-way sync

Google, iCloud, IMAP/SMTP — every account's mail and calendar in one inbox and one calendar. Bring your own domain or grab a free @sta-suite.com address.

Home & lock-screen widgets + Watch

Next event, unread mail, today's tasks, and quick-memo widgets on your iPhone/Galaxy home & lock screen — plus Apple Watch and Samsung Now Bar.

Simple pricing

One STA Pro plan. Free tier that is actually usable.

Stronger together with Stats

STA (four tabs) and Stats (web surveys) connect through one account.

STA is one app for calendar, mail, memo, and tasks. When you need surveys, Stats — a separate web service — connects with the same account.

Pricing

Free to start. One STA Pro plan unlocks every tab.

Common questions

Pricing, platforms, refunds, and privacy.

Does STA replace the previous four apps (Stamp · Stash · Stanza · Stage)?

Yes. The STA app combines Calendar (Stamp), Memo (Stash), Mail (Stanza), and Tasks (Stage) into one app and one account. The old four-app URLs redirect to /apps/sta automatically.

Is my data stored on STA servers?

Mail, memo, and event bodies are not stored on STA servers. Your Google, iCloud, or IMAP accounts are the source of truth and STA lays one screen on top. AI requests send text to Gemini temporarily and discard it right after the response.

Which platforms are supported?

iOS, Android, macOS, and Windows — all from one codebase, released together. Apple Watch Live Activity and Samsung Galaxy Watch Now Bar widgets are supported too.

Is Stats part of STA?

Stats is a separate web SaaS at stats.sta-suite.com that signs in with the same STA account. Survey deadlines auto-appear on STA's calendar tab.
