on.equals is a “smart calculator suite” built around instant results as you type, with no need to press an equals button. It brings 15+ specialized calculators—covering mortgages, compound interest, BMI, auto loans, and more—into a single dashboard. Its key differentiator is the built-in AI assistant, Omar: users can ask what a result means, whether it looks reasonable, or have the system flag unusual inputs.
The product emphasizes real-time calculations, one-handed mobile use, value labels, and saved calculation workflows. For example, users can label a value as “Monthly Payment” and later drag it into other calculations for reuse, avoiding repeated copy-pasting. On the AI side, Omar can generate plain-language summaries, explain mortgage or compound-interest results, and warn about unusual conditions such as a 0% interest rate or an extremely short loan term. The scraped text does not specify the underlying model, the boundaries around financial advice, or multilingual support, so the AI output is best treated as an aid for understanding rather than a basis for investment or loan decisions.
The Basic plan is free and does not require an account. It includes access to all calculators, local/offline storage, basic exports, and 3 Omar requests per day. Pro is currently offered as a limited-time $7.99 one-time purchase, adding cloud sync, saved calculation workflows, PDF/CSV/Excel exports, early access to new features, 2–4 hour support response time, and 10 Omar requests per day. As a one-time price, it offers strong value, though the AI allowance is not especially generous.
on.equals clearly emphasizes a local-first approach and 100% On-Device Processing, which is well suited to personal finance or business calculations. However, Pro includes cloud backup and sync, and the page does not disclose details about cloud encryption, how AI requests are processed, or data retention policies. On the integration side, only file exports are visible at the moment; there is no information about an API, Zapier, Notion, spreadsheet plugins, or similar integrations.
It is a good fit for personal finance users, real estate agents, contractors, freelancers, and others who frequently run what-if calculations and need to explain the results. Chinese-language support is not disclosed, and the page content is in English. There is also no information on whether it is directly accessible from mainland China or whether payment supports domestic bank cards, Alipay, or WeChat Pay, so its access status should be considered unknown. If Chinese support and broader coverage are required, alternatives include Calculator.net, Omni Calculator, Wolfram Alpha, or building custom templates in Excel, Google Sheets, or Chinese spreadsheet tools.
