In this update, Mars helps you:
See the whole board with Mars-2.0 Corona
Tap the model name at the bottom right of the composer, pick Mars-2.0 Corona and set thinking to Low, Medium or High. Rather than answering only the last message, it weighs your long conversation history, multiple files and everyone involved together, plays out the knock-on effects and pushback of each move, then gives you a step-by-step plan. Your draft stays put when you switch models.
→ Think three moves ahead before the conversation that matters.
Bring a friend, you both get credits
Open Invite rewards in Settings or tap the invite banner on the new chat home, then tap Invite friends now: your invite card, QR code and link go straight to the share sheet. When a friend signs up through your link, you each get 200 credits, then another 1,000 each on their first subscription, for up to 100 friends. Invite history shows every friend's status and your credits, and unused reward credits carry over when your plan renews.
→ Share Mars with the people you care about, and you both get more out of it.
Sign in without the wait
The security check now starts while you type. If a background check stalls, you won't see a failure before you tap; tapping Resend restarts it and waits, and a check failure never marks your code as wrong. Sign-in is steadier on mainland China networks: Apple comes first, and if Google sign-in doesn't finish, Mars suggests Apple, phone or email instead.
→ Open the app and get straight in.
A cheaper order never downgrades you
If you already have a higher or lifetime plan, buying a lower-priced plan keeps your current plan, its storage and its end date, and you still get the new order's credits. The order you buy in doesn't cost you anything.
→ Every purchase counts.
Stop means stop
Tap stop and the answer ends and confirms within 5 seconds, with no error. If the model doesn't respond, Mars resends once after 120 seconds instead of waiting until it times out.
→ You set the pace of every conversation.
From screenshot to relationship in one tap
The onboarding tour adds a step: after Mars analyzes your first chat screenshot, it asks to add that person to Relationships. Tap once and they appear on your Relationships home, with your recent conversation in the drawer. The tour fits iPhone Duo and replays from the start when you come back.
→ From day one, see how Mars keeps track of the people in your life.
Drop a Douyin link, Mars reads it
Send Mars a v.douyin.com share link and it reads the account, comments or video, instead of saying the platform isn't supported. It also removes the tracking parameters that identify who shared the link.
→ Paste what you just found, with no need to dig for the full URL.
