Frequently Asked Questions

What makes this tool reliable and stable?

The calculation engine runs entirely in your browser using optimized JavaScript — no server round-trips, no latency, no outages. Enter a formula and get an instant result every time.

What file formats can I upload?

You can upload design files (PDF, images) to reference alongside your calculations. The tool reads the file locally in your browser — nothing is uploaded to any server.

What does 'Remove Ads' include?

A one-time $3.99 payment permanently removes all ads for your account. You keep full access to all calculation and formula features — forever, with no recurring charges.
