Suggest me free Instagram hashtag research tool?

I am looking for a simple hashtag research tool for twitter and Instagram (preference). My basic needs are: - It should suggest me 20 - 25 hashtags on a given keyword - The suggested keywords must have the popularity metrics around it (no of posts or engagement %) The famous keyword research tools are too bulky (dozens of features) and have plans starting from 40$ per month. I don't need all those features. Please suggest me something simple with above-mentioned feature with free access. Thanks.
