What Are The Key Features?
High-fidelity virtual replication of amplifiers by swapping internal components like tubes, transformers, and tone stacks.
A community-driven cloud platform to share, download, and discuss custom amplifier presets.
Advanced speaker cabinet module featuring Celestion impulse responses with customizable mic placement.
How much does it cost?
- Free core version with 36 amp models
- In-app purchases for premium components, expansion packs, and Celestion cabs

The outtake for BIAS AMP 2 - for iPhone
Strengths to defend, gaps to attack
Core Strengths
- Granular component-level customization (tubes, transformers)
- Proprietary Amp Match technology
- Partnership with Celestion for high-quality IRs
- Active ToneCloud community
Critical Frictions
- Critical audio glitches on iOS 16+ (static/feedback)
- Lack of AUv3 support for modern DAW integration
- Separate monetization for iPhone and iPad versions
- Stagnant update cycle (last updated June 2023)
Growth Levers
- Transition to Universal Purchase model to improve brand sentiment
- Implement AUv3 to integrate with hosts like AUM and Cubasis
- Update audio engine for modern iOS compatibility
Market Threats
- DAWs like Cubasis 3 offering built-in, stable amp simulations
- Modern hosts (Loopy Pro) capturing the live-performance segment
- Loss of professional users to more stable, AUv3-compatible plugins
What are the next best moves?
Fix Audio Engine Static/Feedback
Top complaint theme with high frequency on iOS 16+; currently rendering the app unusable for a significant portion of the user base.
Implement AUv3 Support
Medium-frequency complaint; users report the app is 'out of touch' and 'unavailable' in GarageBand without it.
Consolidate to Universal Purchase
High-frequency resentment regarding 'double charging' for iPhone/iPad versions is damaging brand loyalty.
Feature Gaps vs Competitors
- Full-scale multi-track recording (available in Cubasis 3)
- Professional MIDI editor and automation (available in Cubasis 3)
- AUv3 stability and modern plugin hosting (available in Cubasis 3 and AUM)
Key Takeaways
BIAS AMP 2 is a technically superior tone-sculpting tool currently crippled by technical debt and a friction-heavy monetization model. To survive against all-in-one DAWs like Cubasis, the PM must prioritize a stable AUv3 release and resolve the iOS 16 audio glitches immediately.
Where Is It Heading?
Declining
Upset user base reporting critical audio feedback on iOS 16—direct threat to core utility.
Last updated June 2023—indicates maintenance mode or stalled development during a period of high technical failure.
Lack of AUv3 support in 2023/2024—increasingly isolates the app from the modern iOS production ecosystem.
