Can i pay monthly or daily license. i am still trying it out on desktop?

No, Genymotion Desktop licenses are sold as annual-style subscriptions, not daily or monthly plans. You can try Genymotion Desktop Pro for 30 days, and the free edition is available with no license required.

For Desktop, the pricing page lists Free, Educational, Individual, Business, and Premium options. The free edition is for personal use, and the trial is the way to test Pro features before buying.
