Built this over the weekend because I was frustrated with calculator apps that are either too complex or filled with ads.

CalcPercent is intentionally simple - 6 percentage calculators, everything runs in your browser, no tracking, completely free.

Would love feedback from the HN community on what features to add next!

Built this over the weekend because I was frustrated with calculator apps that are either too complex or filled with ads.

CalcPercent.net has 6 percentage calculators (basic, increase/decrease, difference, reverse, discount). Everything runs in your browser - no tracking, no data collection, completely free.

Built it in a few hours and launched today. Would love feedback from the HN community on what features to add next!
