AppTweak for ASO - I have tested several platforms but always return to AppTweak. They recently added an Apple Search Ads management platform too.

You can use AppTweak's automated exports to export your App Store and Google Play data into csv. - very easy solution.
We use AppTweak for ASO. It is by far the most comprehensive ASO tool out there. They have extensive keyword research features in many languages and a great ASO timeline feature to spy on competitor metadata updates, A/B tests and In-App Events. They have a great support team and many recourses to learn about ASO.
