User reviews

Wrong output

First gripe: your calculation is wrong. I compared with 3 other calculators on 3-location measurement and your app was odd man out (telling me I was lower by about 1.5%)

Second gripe: ads are overkill. No, I’m not paying a subscription, but I’m also not willing to watch an ad for 20-30 seconds before each daily measurement when I can just use a web app with no advertisements. I’m tempted to write my own iOS app and just charge a flat $1.00 fee for the life of the app — it’s not rocket science…

Response from developer

Hi Jason, it looks like the combination of formulas you are using could be different from the one you are comparing against. Of course, you are free to create your own app, nowadays is way easier 👍🏻
