The lack of recent updates (203 days since last store activity) limits its ability to compete with more frequently updated tools in the broader home-maintenance space. ## Monetization Strategy - **Model:** Freemium - **Tiers:** Free tier with basic logging and LSI calculation, Pro tier with charts and inventory management - **Analysis:** The freemium model gates advanced data visualization and inventory tracking behind a Pro tier to convert active users. ## SWOT Analysis {#swot} **Core Strengths:** - LSI calculator provides technical barrier for equipment-focused users **Growth Levers:** - Localized chemical supply tracking could integrate with regional retail partners ## Recent Changes (v2 → v3) {#recent-changes} PoolWise remains in a maintenance-only state with no functional changes to the feature set or pricing model. The analysis reflects a shift in competitive outlook, moving from a focus on property management growth to concerns regarding displacement by broader smart home platforms. **Overall trend**: Stable **Compared at**: 2026-09-03 ### Medium-impact changes - **[Shifted] Strategic Threat Re-evaluation** (swot) ### Low-impact changes - **[Shifted] Contrarian Take Pivot** (positioning) ## App Momentum (Zombie) {#momentum} - No major releases in six months - Maintenance-only cadence > **Cadence:** 1 total versions · 0 majors in last 6 months · 202 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} PoolWise: Pool Maintenance is an utilities app that is free with in-app purchases. > **Bottom Line:** The LSI calculator provides a clear technical value, but the six-month development silence undermines the app's utility as a reliable maintenance tool. Restoring a regular update cadence is necessary to prove the product is not abandoned. **Best for:** Pool and spa owners ranging from novices to professionals who require precise chemical tracking and equipment protection. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Ship a minor stability update because the six-month silence erodes user trust → restore baseline reliability ### Outlook: Declining Users report: The pool maintenance category is shifting toward integrated smart-home solutions that automate data entry, leaving manual logging apps like PoolWise exposed. Without a return to active development, PoolWise will likely lose its position to automated rivals that offer lower friction for the user. - 🔴 The 203-day update gap suggests the app is in maintenance mode, which reduces its appeal to new users seeking active support. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Freemium | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **PoolWise: Pool Maintenance** (this app) | N/A/5 | N/A | 天泽 张 | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | ## Company Profile - **Developer:** 天泽 张 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/poolwise-pool-maintenance/id6758569364?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is PoolWise suitable for professional pool maintenance?
