Pros and cons

EZCalc

Pros

  • 100% free with zero paywalls, forced subscriptions, or mandatory account registrations
  • Client-side browser computation protects privacy by keeping health and financial inputs on device
  • Broad multi-domain calculator selection covering health, pregnancy, loans, gold, land, and math
  • Specialized regional calculators including traditional gold weights (Vori, Ana, Roti) and land dimensions
  • Fast, lightweight modern dark mode web interface with instant reactive calculations
  • Detailed insights including amortization tables, trimester schedules, and gestational fruit sizes

Cons

  • Ad-supported interface displaying standard web advertising
  • No user accounts to save, sync, or export calculation histories across devices
  • Lacks a developer REST API for automated batch calculations

Grammarly

Pros

  • Works across desktop, browser, Office, Google Docs and mobile keyboards, so suggestions follow you between apps.
  • Free plan covers core grammar, spelling and tone visibility with 100 AI prompts per month.
  • Pro adds tone adjustment, full-sentence rewrites, plagiarism and AI-text detection in a single subscription.
  • Team features include style guides, brand tones, analytics and user groups; Enterprise adds SSO, SCIM and audit logs.
  • Public REST APIs exist for analytics, licence management, writing score and detection.

Cons

  • Monthly billing for Pro is $30, versus $12 per month on annual billing, so month-to-month use costs 2.5 times as much.
  • Third-party tests of the AI Detector report notable false-positive rates (figures range from 14.2% to 34% across sources), so it is unreliable as proof.
  • An App Store reviewer criticizes the iOS keyboard setup for pushing users to grant broad access.
  • Experienced writers on forums report turning off many suggestions; advanced features are gated behind Pro.
