Verdict
The clearest difference is rating: Linear Interpolation Master at 4.7 against I&C Tech Tools's 1.0. Linear Interpolation Master also leads on ratings volume (176 vs 1) and iOS requirement (11.0 vs 15.1). I&C Tech Tools's advantage is ads (none vs shown) and update cadence (every 4 days vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Linear Interpolation Master sells 3 one-off in-app purchases and I&C Tech Tools sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
Linear Interpolation Master holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Linear Interpolation Master has 176 ratings behind it against 1, so its average is the more settled of the two.
Linear Interpolation Master ships an update every 5 months, I&C Tech Tools every 4 days. The most recent releases landed on September 27, 2026 and September 26, 2026 respectively.
