# Periodic Table vs QuantumKamil

Periodic Table and QuantumKamil 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. Periodic Table sells 2 one-off in-app purchases and QuantumKamil sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Periodic Table ships an update every 8 days, QuantumKamil every 4 days. Both last shipped on October 31, 2026.
