The caveats
AppstorePulse. Built by the maker of Wide Bundles, a bundle app in the Upsell and bundles category. If you compete there, you would be handing your keyword strategy to a company that competes in the same category. The free tier is one app, three keywords and one competitor. Search volume is a relative tier estimate, not real numbers.
SASI. Run by Mantle, whose billing platform is winding down. SASI's own site says nothing about its future, and it was being updated on 23 October 2026. It is free, with no plan or terms that say how long that lasts. Do not make it the only copy of data you depend on.
