# treezi vs ISA Arborist Exam Prep

ISA Arborist Exam Prep also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (329 vs 17). treezi's advantage is in-app purchases (none vs 9) and review sentiment (78% vs 43%). On price, ads and device support there is nothing between them.

Both are free to download. ISA Arborist Exam Prep sells 8 in-app purchases, starting at $4.99 per month. treezi asks for nothing beyond the download.

Written reviews complicate that: 78% of treezi's written reviews are positive against 43% of ISA Arborist Exam Prep's, so the app with the better star average is not the one people write more warmly about.
