Is there any recommend dua to be read just before iftaar?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

The fasting person has a supplication that is answered when he breaks his fast as the Prophet said: “The fasting person has a supplication when he breaks his fast that is undoubtedly answered” [Ibn Majah]

Therefore, one should be keen on supplicating at the time of breaking the fast about what he wishes from the good of this world and the Hereafter, and say the supplication that the Prophet used to say when breaking the fast: “The thirst is gone, the veins are wet, and the reward is confirmed – Allah willing.” [Abu Dawood and An-Nasaa'i]

Besides, Ibn Majah, may Allaah have mercy upon him, narrated in his Sunnan that 'Abdullah ibn 'Amru  narrated that the Prophet used to say when breaking the fast: “O Allah, I ask you by Your Mercy, which has encompassed everything, to forgive me.”

Allah knows best.
