The lack of recent updates (105 days) creates a vulnerability against competitors with more active development cycles. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier with core calculators, Pro tier with one-time purchase for full professional toolset - **Analysis:** The one-time purchase model provides a clear value proposition for professionals who avoid recurring subscription costs. ## SWOT Analysis {#swot} **Core Strengths:** - Offline-first architecture functions as a distribution barrier in industrial environments. **Growth Levers:** - Localized NEC-equivalent standards could expand the user base beyond US-centric NEC focus. ## App Momentum (Maintenance) {#momentum} - Ships maintenance-only updates. - Last major release June 2026. > **Cadence:** 1 total versions · 0 majors in last 6 months · 104 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Electrical Calculator: NEC is an utilities app that is free with in-app purchases. > **Bottom Line:** The one-time purchase model secures a loyal professional base, but the 105-day update gap risks the app's relevance as NEC codes evolve. Maintaining code accuracy is the mechanism that will preserve the app's value against more active rivals. **Best for:** Electricians, electrical students, and DIY professionals requiring NEC-compliant calculation tools. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit the current NEC code version coverage because the 105-day update gap risks falling behind current code cycles → maintain professional trust. ### Outlook: Stable The electrical utility market is increasingly shifting toward subscription models, leaving Electrical Calculator: NEC in a stable but vulnerable position. By maintaining a one-time purchase model, the app remains advantaged for price-sensitive professionals, but the lack of active development cadence could erode this lead if competitors offer more frequent code updates. - ⚪ The 105-day update gap indicates a maintenance-only cadence, which signals stability to professionals but risks falling behind evolving NEC code requirements. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Electrical Calculator: NEC** (this app) | N/A/5 | N/A | Fedor Tryakin | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [App For Siri Commands Tips](https://marlvel.ai/apps/app-for-siri-commands-tips) | N/A/5 | N/A | Anh La Phan Son | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Bin Days - Bin Reminder](https://marlvel.ai/apps/bin-days-bin-reminder) | N/A/5 | N/A | Vicki Partridge | ## Company Profile - **Developer:** Fedor Tryakin ## Data Sources & Links - **App Store ID:** 6781034650 - **Sources:** App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*App For Siri Commands Tips*](https://marlvel.ai/apps/app-for-siri-commands-tips) (Anh La Phan Son) · N/A Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Bin Days - Bin Reminder*](https://marlvel.ai/apps/bin-days-bin-reminder) (Vicki Partridge) · N/A Rating - [*Controller Tester FGC*](https://marlvel.ai/apps/controller-tester-fgc) (Aaron Lowe) · 5.0/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Gear Ratio Calculator & RPM*](https://marlvel.ai/apps/cog-gear-ratio-calculator) (Linh Phan Nhat Khanh) · N/A Rating - [*MDflow Web Clipper*](https://marlvel.ai/apps/mdflow-web-clipper) (DataOps, s.r.o.) · N/A Rating - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating ## Frequently Asked Questions {#faq} ### Is Electrical Calculator: NEC free to use?
