The lack of updates since early 2022 signals a maintenance-mode posture that limits its competitive relevance against actively supported audio utilities. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** Simple MIDI is distributed as a free, open-source tool with no visible monetization or IAP gates. ## 🟡 User Sentiment (Medium Confidence: 4 of 4 reviews analyzed) {#user-sentiment} - **Overall Rating:** 3.75/5 - **Platform Split:** iOS 3.8/5 (8 ratings) - **Overall Sentiment:** Mixed ### Top Praises - **Realistic piano instrument emulation provides high quality audio output for non-musicians using midi files** ### Top Complaints (Impact Areas) - **Application crashes immediately upon attempting to open specific midi files for playback during sessions** ## SWOT Analysis {#swot} **Core Strengths:** - Open-source codebase facilitates educational community visibility **Growth Levers:** - Expanding AudioKit-based features for Swift developers ## What's New - **Latest (v1.1, 4 years ago):** Introduced a realistic piano instrument. ## App Momentum (Zombie) {#momentum} - Dormant since early 2022. - No feature expansion in 4 years. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1721 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Simple MIDI is a music app that is completely free. It holds a 3.75/5 rating from 8 reviews. > **Bottom Line:** Simple MIDI serves as a technical portfolio piece rather than a consumer product, and addressing file-loading crashes would improve its utility as an educational tool. The current maintenance-mode status suggests the developer should prioritize stability over feature expansion to preserve the codebase's value. **Best for:** Music technology students and developers interested in Swift and AudioKit. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit file-loading logic because crashes are the top-reported complaint → reduce churn ### Outlook: Stable The music technology education market is shifting toward integrated, cloud-based coding environments, leaving static MIDI players like Simple MIDI in a legacy position. Without a renewed update cadence, the app will likely lose its relevance as a learning tool for the current Swift Playgrounds ecosystem. - 🔴 The 4-year update gap indicates the project is in maintenance mode, which increases the risk of future iOS compatibility failures. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.75/5 | | Total Reviews | 8 | | Sentiment | Mixed (50/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Simple MIDI** (this app) | 3.75/5 | Mixed | Evan Murray | | [SyncTimer - Ensemble Stopwatch](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) | 5.0/5 | Thrilled | Sebastian Suarez-Solis | | [ヨルシカ](https://marlvel.ai/apps/com-yorushika-sp) | 4.8/5 | N/A | Fanplus, Inc. | | [あいみょん](https://marlvel.ai/apps/net-aimyong-sp) | 4.5/5 | N/A | Fanplus, Inc. | | [イントリズム](https://marlvel.ai/apps/jp-rc-into-rhythm) | 3.5/5 | N/A | RedinC | | [クリープハイプ](https://marlvel.ai/apps/creephyp-sp-browsingapp) | N/A/5 | N/A | Fanplus, Inc. | ## Company Profile - **Developer:** Evan Murray - **Website:** [https://auraaudio.io](https://auraaudio.io) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/simple-midi/id1602546107?uo=4) - **Dev Site:** [Official Website](https://auraaudio.io) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*SyncTimer - Ensemble Stopwatch*](https://marlvel.ai/apps/synctimer-ensemble-stopwatch) (Sebastian Suarez-Solis) · 5.0/5 Rating | Excellent Sentiment - [*ヨルシカ*](https://marlvel.ai/apps/com-yorushika-sp) (Fanplus, Inc.) · 4.8/5 Rating - [*あいみょん*](https://marlvel.ai/apps/net-aimyong-sp) (Fanplus, Inc.) · 4.5/5 Rating - [*イントリズム*](https://marlvel.ai/apps/jp-rc-into-rhythm) (RedinC) · 3.5/5 Rating - [*クリープハイプ*](https://marlvel.ai/apps/creephyp-sp-browsingapp) (Fanplus, Inc.) · N/A Rating - [*マカロニえんぴつ*](https://marlvel.ai/apps/com-macaroniempitsu-fc) (Fanplus, Inc.) · 3.1/5 Rating - [*100.1 Jack FM*](https://marlvel.ai/apps/100-1-jack-fm) (NRG Media) · 1.0/5 Rating - [*100.1 WJRZ*](https://marlvel.ai/apps/100-1-wjrz) (Beasley Broadcast Group) · 4.8/5 Rating | Excellent Sentiment - [*100.3 The Wolf*](https://marlvel.ai/apps/100-3-the-wolf) (SummitMedia, LLC) · 4.1/5 Rating - [*100.7 KIK-FM*](https://marlvel.ai/apps/100-7-kik-fm) (Hubbard Radio) · 4.3/5 Rating ## Frequently Asked Questions {#faq} ### Is Simple MIDI suitable for professional music production?
