Nimbus8 Pro (one-time in-app purchase) unlocks: • Cirrus — repo-aware coding agent with inline diffs • Ashe — confirm-first background agents and scheduled Hands • Mist — hybrid local search with optional web layer • Mirage — on-device image generation • Stratus — camera, OCR, and vision Q&A • Overture — speech-to-text, text-to-speech, and audio tools • Zephyr — on-device translation • Haze — cross-module memory and recall Built native in Swift with a Rust core. No Nimbus account required. Optional cloud inference. No telemetry. Models you choose are downloaded to your device and run locally. Processing stays on your phone unless you explicitly enable optional network features (such as web search or a BYOK cloud provider in Cirrus). Purchase Nimbus8 Pro once through Apple In-App Purchase. Restore anytime with your Apple ID. Family Sharing follows Apple's IAP rules. Privacy policy: https://trynimbus.org/privacy.html

Verdict
The clearest difference is in-app purchases: Duora at none against Nimbus8's 2. Nimbus8's advantage is update cadence (every 2 days vs every 7 months). On price, ads, device support and iOS requirement there is nothing between them.
