# iBigCalc vs G1RL

The clearest difference is in-app purchases: iBigCalc at none against G1RL's 10. G1RL's advantage is ads (none vs shown) and iOS requirement (15.1 vs 17). On price, update cadence and device support there is nothing between them.

Both are free to download. G1RL sells 10 one-off in-app purchases. iBigCalc asks for nothing beyond the download.

iBigCalc ships an update every 3 weeks, G1RL fortnightly. The most recent releases landed on September 30, 2026 and October 8, 2026 respectively.
