The lack of recent feature updates and the presence of UI regressions suggest a maintenance-mode posture that limits its ability to capture new market share. ## Monetization Strategy - **Model:** Free - **Tiers:** Free with ads - **Analysis:** The app operates as a free, ad-supported utility with no IAP or subscription tiers. ## 🟡 User Sentiment (Medium Confidence: 20 of 20 reviews analyzed) {#user-sentiment} - **Overall Rating:** 3.83/5 - **Platform Split:** Android 3.8/5 (54 ratings) - **Overall Sentiment:** Mixed ### Top Praises - **The simple and accurate calculation interface provides immediate utility for users measuring lumber dimensions** - **The absence of intrusive advertisements allows for a clean and focused user experience during calculations** ### Top Complaints (Impact Areas) - **Input fields disappear or become unreadable following recent updates, hindering the core calculation workflow** ## SWOT Analysis {#swot} **Core Strengths:** - Simple, ad-free interface provides immediate utility for lumber calculations **Growth Levers:** - Adding a saved-project history would increase session utility for contractors ## What's New - **Latest (v33.0, 3 months ago):** The update focuses exclusively on UI refinements. ## App Momentum (Maintenance) {#momentum} - Ships minor updates at 102-day cadence. - Latest release focuses exclusively on UI. > **Cadence:** 2 total versions · 0 majors in last 6 months · 102 days since last update · 10 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Board Foot Calculator: Lumber is an utilities app that is completely free. With a 3.83/5 rating from 54 reviews, it shows mixed user reception. > **Bottom Line:** Board Foot Calculator's utility rests on its simplicity, but the current UI regressions and freezing issues invalidate that value proposition. Addressing these stability failures is the only way to prevent further churn and restore the app's baseline utility for woodworkers. **Best for:** Woodworkers, carpenters, contractors, and DIY users requiring quick material volume and cost estimates. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Rebuild input field logic because users report disappearing text after the latest update → restore core utility ### Outlook: Declining The utility market for lumber estimation is consolidating around apps that offer reliable, bug-free performance. Board Foot Calculator's current stability issues and lack of feature investment leave it exposed to churn, as users prioritize functional reliability over simple design. The app must stabilize its core workflow to remain relevant against competitors. - 🔴 UI regressions in the latest update (disappearing input fields) erode the core calculation workflow, which compounds the rating drag already visible on Android. - 🔴 The 102-day update cadence without feature expansion suggests the app is in maintenance mode, leaving it vulnerable to more active competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.83/5 | | Total Reviews | 54 | | Sentiment | Mixed (55/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Board Foot Calculator: Lumber** (this app) | 3.83/5 | Mixed | Jun Yamabe | | [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:** Jun Yamabe - **Website:** [https://t5kit.github.io/junapps-support/index.html](https://t5kit.github.io/junapps-support/index.html) ## Data Sources & Links - **App Store ID:** 6780563005 - **Google Play ID:** com.simago.boardfoot - **Dev Site:** [Official Website](https://t5kit.github.io/junapps-support/index.html) - **Sources:** Developer website content, App store metadata, User reviews. ## 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 Board Foot Calculator free to use?
