# Techline Calculator vs ADI

The clearest difference is rating: ADI at 4.0 against Techline Calculator's 3.1. Techline Calculator's advantage is ads (none vs shown) and review sentiment (25% vs 0%). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ADI holds the better App Store score, 4.0 against 3.1. Both are backed by a comparable volume of ratings — 7 and 4 respectively. Written reviews complicate that: 25% of Techline Calculator's written reviews are positive against 0% of ADI's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 10, 2026 and June 1, 2026 respectively.
