On-screen damage and speed calculator for competitive mobile matches
Experience Overlay Damage Calculator by RAKKO-LAB to calculate damage and speed instantly during team battles. The app places a floating window over your game to run real-time calculations and OCR-based opponent recognition without leaving the match. Features include damage and speed calculators, party management, battle history logging, and multilingual interface with automated OCR registration. Designed for competitive team gamers who need immediate tactical numbers during live matches to inform game decisions.
How the overlay operates without interrupting gameplay
The app runs as a floating window that sits on top of the battle screen, so calculations and comparisons appear without switching apps. It requires the 'Display over other apps' permission to show the overlay, and it reads on-screen information only rather than altering game files. In practice, that lets players trigger a damage or speed check mid-match while keeping the battle visible.
Does OCR and language support affect automated setup?
Automated OCR recognition captures opponent teams from the preview screen, which the developer notes reduces manual entry errors. The interface supports six languages for general use, yet the OCR-based 'My Party' registration currently accepts the Japanese client only, with other-language OCR support planned. This means automated party import may be limited for users on non-Japanese game clients, requiring manual registration in some cases.
Is it safe for competitive sessions and useful for post-match review?
The tool does not modify game data or automate gameplay, it operates by reading on-screen content only, and user reception highlights a non-intrusive overlay and time-saving OCR features. In addition, the app records battle history and stores party data for later review, which helps tactical research. These behaviours keep the app focused on analysis rather than interaction with the game itself.
The app suits competitive players who accept a language-based trade-off
The tool is a practical option for competitive gamers who need instant on-screen tactical numbers during matches. Its main limitation is the current OCR registration support limited to the Japanese client, which can force manual setup for some users. Given that trade-off, the app serves players who prioritise live calculations and post-match review while accepting that automated registration may be partial for now.
