About All in One Formula - Math AI
All in One Formula - Math AI is an education app from developer Raj Dev Barman, distributed under the package name com.rkb.allinoneformula.free. Its title points to a single purpose: pulling mathematical formulas together in one place, and the AI wording in the name hints at an assistant-style experience rather than a plain list. The current build is version 1.3.7 and occupies 39.1 MB of space.
A Focused Math Reference The app sits in the education category, which frames it as a study aid rather than a casual game or a work tool. Anyone revising mathematics can expect the material to be organised around formulas, so the references you need are gathered together instead of being scattered across separate books or handwritten notes.
Storage and Device Compatibility At 39.1 MB the install is modest, so it should not crowd other applications off a typical handset. The build requires Android 7.0 or newer, and devices running a more recent release of the system should have no difficulty launching and keeping it.
Version 1.3.7 Released 2026-10-03 Version 1.3.7 is the release listed here, carrying the date 2026-10-03. If you already have an earlier build on your device, this is the one that matches the current listing, and updating keeps your installed copy in step with what is published.

Note that the content rating for this listing is unknown, so no age classification is given here.
