Most AI apps are $10–$20 a month, forever. Nimbus8 is one payment — and the model runs on the chip you already own. Break-even versus a $10/mo subscription: two months.

Common questions

Questions, answered straight.

What's free vs. Pro?
Gale (chat) is free forever — no payment, no trial, no asterisk. Install Nimbus8, pick an open model (Llama, Qwen, Gemma, Mistral), and start chatting. Nimbus8 Pro is one payment that unlocks the other 7 premium modules — Cirrus (code), Ashe (agents), Mist (search), Mirage (image), Stratus (vision), Overture (audio), Zephyr (translation), plus Haze (memory).
Is this a subscription?
No. One payment, yours forever. There's no auto-renewal, no monthly bill, and no Nimbus account to log into. Purchase and restore are handled by Apple In-App Purchase through the Apple ID on your iPhone or iPad.
What does "lifetime" actually cover?
Every Nimbus8 v1.x release. New modules, new model integrations, every UI refresh — all included. If we ever ship a paid v2 with a fundamentally different runtime, your v1 lifetime stays valid forever and you'll get a generous upgrade path. We won't pull a rug.
What happens if Nimbus8 shuts down?
Your installed app keeps working. There's no server to turn off — every model runs on your phone. We commit to publishing the final unlocked build (or open-sourcing the runtime) before any wind-down so you're never stranded.
Does this work on multiple devices?
Yes. Pro restores through the App Store on Apple devices signed into the purchasing Apple ID. Family Sharing follows Apple's in-app purchase rules.
Can I buy outside the App Store?
No. Nimbus8 Pro is a digital feature unlock, so purchase and restore happen through Apple In-App Purchase only. This page can link you to Nimbus8 on the App Store, but it does not sell, collect payment, or issue license tokens.
How do I restore after I pay?
Open Nimbus8, go to Settings → Nimbus8 Pro, and tap Restore Purchases. Apple confirms the purchase for the signed-in Apple ID and Nimbus8 refreshes your Pro entitlement.
Where is my payment information stored?
Apple handles the payment. Nimbus8 never sees your card and does not store checkout email, receipt IDs, or bearer license tokens. See the privacy policy for the full picture.

Pay once. Yours forever.
