The lack of recent updates over the last 148 days signals a maintenance-only posture rather than active market expansion. ## Monetization Strategy - **Model:** Free - **Tiers:** Free app with no stated in-app purchases - **Analysis:** The app functions as a free utility to support the developer's hardware sales ecosystem. ## SWOT Analysis {#swot} **Core Strengths:** - 11 specialized hardware tools replace custom coding **Growth Levers:** - Community template sharing could increase utility ## Recent Changes (v2 → v3) {#recent-changes} The app remains in a maintenance-only state with no functional updates or feature additions since launch. The primary changes are limited to a more precise articulation of the risks and opportunities within the SWOT analysis. **Overall trend**: Stable **Compared at**: 2026-08-27 ### Medium-impact changes - **[Shifted] SWOT Analysis Update** (swot) ### Low-impact changes - **[Shifted] Narrative Refinement** (positioning) ## App Momentum (Zombie) {#momentum} - Dormant for 148 days. - No releases since initial launch. > **Cadence:** 1 total versions · 1 majors in last 6 months · 148 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} DIYables Bluetooth STEM is an education app that is completely free. > **Bottom Line:** DIYables Bluetooth STEM provides a functional toolset for hardware hobbyists, but the lack of development activity since launch suggests a maintenance-only posture that limits long-term user retention. **Best for:** STEM students, hobbyists, and IoT developers working with Arduino and ESP32 platforms. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit BLE connectivity against latest OS requirements because the app has been dormant for 148 days → prevent silent failure ### Outlook: Stable The market for hardware-companion utilities remains stable, but DIYables Bluetooth STEM is currently in a maintenance-only state. The lack of updates over the last 148 days suggests the developer is focused on hardware sales rather than mobile-first feature expansion. - ⚪ The 148-day development silence indicates the app is a static support tool rather than an active product, which limits future growth potential. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **DIYables Bluetooth STEM** (this app) | N/A/5 | N/A | SY KHANH HO | | [AlgoApp - Flashcards](https://marlvel.ai/apps/algoapp-flashcards) | 4.5/5 | n/a | AlgoApp Inc | | [Elevate - Brain Training Games](https://marlvel.ai/apps/elevate-brain-training-games) | 4.7/5 | n/a | The Mind Company | | [Flashcards Deluxe](https://marlvel.ai/apps/flashcards-deluxe) | 4.5/5 | N/A | OrangeOrApple.com | | [Flash Cards Flashcards Maker](https://marlvel.ai/apps/flash-cards-flashcards-maker) | 4.0/5 | Mixed | Infinite Wave Media, LLC | | [Flashcards maker - AI generate](https://marlvel.ai/apps/flashcards-maker-ai-generate) | 4.1/5 | Mixed | Teleprompter LLC | ## Company Profile - **Developer:** SY KHANH HO - **Website:** [https://diyables.io](https://diyables.io) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/diyables-bluetooth-stem/id6760932195?uo=4) - **Dev Site:** [Official Website](https://diyables.io) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*AlgoApp - Flashcards*](https://marlvel.ai/apps/algoapp-flashcards) (AlgoApp Inc) · 4.5/5 Rating - [*Elevate - Brain Training Games*](https://marlvel.ai/apps/elevate-brain-training-games) (The Mind Company) · 4.7/5 Rating - [*Flashcards Deluxe*](https://marlvel.ai/apps/flashcards-deluxe) (OrangeOrApple.com) · 4.5/5 Rating - [*Flash Cards Flashcards Maker*](https://marlvel.ai/apps/flash-cards-flashcards-maker) (Infinite Wave Media, LLC) · 4.0/5 Rating - [*Flashcards maker - AI generate*](https://marlvel.ai/apps/flashcards-maker-ai-generate) (Teleprompter LLC) · 4.1/5 Rating - [*Impulse - Brain Training*](https://marlvel.ai/apps/impulse-brain-training) (GMRD Apps Limited) · 4.6/5 Rating - [*Peak - Brain Training*](https://marlvel.ai/apps/peak-brain-training) (Synaptic Labs) · 4.7/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating ## Frequently Asked Questions {#faq} ### Is DIYables Bluetooth STEM free to use?
