# LoJack vs CORE Calculator App

LoJack and CORE Calculator App both sit at 4.9 stars, but that hides the real split: 100% of CORE Calculator App's written reviews are positive against 44% of LoJack's. CORE Calculator App also leads on monetization model (free with in-app purchases vs subscription) and iOS requirement (14.0 vs 16.0). LoJack's advantage is ratings volume (94K vs 11) and chart position (#186 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. LoJack sells 1 in-app purchase, starting at $129.99 per year and CORE Calculator App sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for LoJack against 5.0 for CORE Calculator App. That said, the two scores are not equally well evidenced: LoJack has 94K ratings behind it against 11, so its average is the more settled of the two.
