The MatrixAnalysis is carefully designed to be a simple and elegant app. This app has tools to help you analyze matrices like finding eigenvalues and eigenvectors, diagonalization, QR, SLU, LU factorization. This app can also be used to do matrix operations like, finding inverse, determinant, dot product, cross product, and much more. You can also do elementwise operations and scalar operations. Want to do fast fourier transform (FFT) or inverse fourier transform (IFFT), this app is capable of IFFT Want to find an pseudo inverse of a non-square matrix, this app has you covered Want to know a rotation matrix for a given angle or rotate a vector by the given angle? This app has you covered. The expressions and the solutions are displayed in beautiful mathematical way. Once the expressions are solved, a beautifully written solutions are created that you can share with other or save it locally. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. There is also a Study page to help you with learning some important matrix vector formulas and some useful technique. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
Atomic Spectra
This reference app provides detailed information on strong line atomic emission spectra within the visible range. Users can search for elements by name, symbol, or atomic number and inspect individual spectra lines. It offers interactive features to visualize and navigate spectral data.
- Visible range spectra (380-740nm)
- Search by element name, symbol, or atomic number
- Sort by name, symbol, or spectra line count
- Inspect individual spectra lines
- Interactive spectrum visualization

Verdict
The clearest difference is update cadence: Matrix at every 5 weeks against Atomic Spectra's every 19 months. Matrix also leads on iOS requirement (15.1 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
