While building Haseba, we focused most of our energy on the user interface. We think that the key to any great app is a beautiful, and simple design that works seamlessly with the app's features. • Scientific Calculator • Voice Calculator • History (Swipe down in the display area) • Copy and Paste • Dynamic Light / Dark Themes (and icons) • Larger Buttons Option • Available on Apple Watch Memory Slots • Save a value inside one of 11 memory slots to use them in calculations later • A value may be the result of a previous calculation, or pasted from the clipboard into a memory slot • The process to store a value in a memory slot is very easy and fast, just drag down a memory slot • Copy memory slot value to clipboard • After having a set of occupied memory slots, you can apply one of six different operations on them in one tap: sum, average, product, median, max, min, of the occupied memory slots. ___________________________________________ Terms & Privacy: https://bit.ly/haseba-terms-privacy Need help or have questions?

Verdict
The clearest difference is in-app purchases: Locker Guard at none against Haseba Calculator's 7. Locker Guard also leads on update cadence (every 3 days vs every 2 months). Haseba Calculator's advantage is iOS requirement (17.0 vs 26.0). On price, ads and device support there is nothing between them.
