How much is that in Bitcoin? What remains after a percentage deduction? CoinCalc puts the calculation and the conversion in one app. Choose two currencies, enter an amount or a full expression, and convert the result using public market quotes against USDT. THE ESSENTIALS, FREE • A calculator with the complete formula on screen. • Addition, subtraction, multiplication, division and percentages. • Conversion between supported cryptocurrencies. • Five customizable quick-access currencies. • A focused dark interface for iPhone and iPad.

Verdict
The clearest difference is in-app purchases: Turtle at none against CoinCalc's 2. Turtle also leads on iOS requirement (13.0 vs 16.0). CoinCalc's advantage is update cadence (weekly vs every 3 months). On price, ads and device support there is nothing between them.
