# The Chippy Calc vs MasterBuilder Pro

The Chippy Calc and MasterBuilder Pro are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. The Chippy Calc sells 3 in-app purchases, starting at $3.99 per month and MasterBuilder Pro sells 3 in-app purchases, starting at $9.00 per month. Whichever you choose, the download price is not the number that matters.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 9, 2026 and September 30, 2026 respectively.
