Without a shift toward a paid-tier model, the app will continue to see user attrition as the ad density remains the primary point of friction. - 🔴 Aggressive advertising overlays in the latest version erode the daily active habit, which compounds the negative sentiment already visible in reviews. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.4/5 | | Total Reviews | 42 | | Sentiment | Upset (10/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Calculator C - Snappy History** (this app) | 4.4/5 | Upset | DIGITALNAUTS INC. | | [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:** DIGITALNAUTS INC. - **Website:** [https://digitalnauts.com/](https://digitalnauts.com/) ## Data Sources & Links - **App Store ID:** 1174687792 - **Dev Site:** [Official Website](https://digitalnauts.com/) - **Sources:** Developer website content, About us / company information, 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 - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating - [*Pick and Pull: Junkyard Finder*](https://marlvel.ai/apps/pick-and-pull-junkyard-finder) (Vladimir Kostadinov Stoyanov) · 3.7/5 Rating ## Frequently Asked Questions {#faq} ### Does Calculator C have intrusive ads?
