(Strategic Takeaway) {#so-what} All Percentage Calculator is an utilities app that is completely free. It holds a 2/5 rating from 1 review. > **Bottom Line:** All Percentage Calculator relies on a privacy-first, offline-only mechanism that serves a clear user need, but the lack of revenue and social proof leaves the app vulnerable to more active rivals. A pivot toward sustainable monetization would unlock the capital needed to defend its position. **Best for:** Users requiring quick, private, and offline financial math tools for daily tasks like shopping, tax, or interest calculations. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit user-onboarding flow because the single-rating count indicates low discovery → increase rating velocity ### Outlook: Stable The utility category is consolidating around apps that offer both offline privacy and frequent feature updates. All Percentage Calculator is currently advantaged by its privacy-first architecture, but the lack of revenue and social proof leaves it exposed to rivals that can subsidize growth through active live-ops. - ⚪ The 57-day update gap suggests a maintenance-only cadence, which limits the app's ability to respond to category-wide feature shifts. - 🔴 A single store rating prevents the app from building the social proof necessary to compete with established, high-volume utility rivals. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 1 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **All Percentage Calculator** (this app) | 2/5 | N/A | Alper Sumer Guc | | [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:** Alper Sumer Guc - **Website:** [https://www.deve.net/](https://www.deve.net/) - **Social:** [YouTube](https://www.youtube.com/@DeveApps) ## Data Sources & Links - **App Store ID:** 6780200350 - **Dev Site:** [Official Website](https://www.deve.net/) - **Sources:** Developer website content, About us / company information, 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 All Percentage Calculator safe to use for private financial math?
