## Version history (last 5 releases)

### 1.3.0 — 2026-08-03

Home Screen Widgets (new)

Long-press your Home Screen → "+" → search "AIYuan". Two widgets are available:
· Signal — today's status and allocation for a single strategy
· Overview — all your subscribed strategies on one screen

Widgets show only the strategies that actually fired a signal today, marked in red, so you can see at a glance what needs your attention. On a quiet day they show the most recent signal instead. Tap to open that strategy.

Scan to Sign In on the Web (new)

Scan the QR code on our website with the app to sign in there — no need to type your account again.
