# qubotron vs PiKuBo

The clearest difference is ads: PiKuBo at none against qubotron's shown. PiKuBo also leads on rating (4.6 vs 4.2) and review sentiment (87% vs 67%). qubotron's advantage is update cadence (weekly vs every 5 weeks) and iOS requirement (12.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. qubotron sells 1 one-off in-app purchase and PiKuBo sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
