Why IV Checking Matters
An IV checker helps players understand hidden strength. CP alone does not show the full story. HP, base stats, level, and appraisal clues all matter. Two monsters can show the same CP yet have very different attack, defense, and stamina values. This calculator searches every legal IV set from zero to fifteen. It then compares each set with your visible CP and HP. The result is a ranked list of possible matches.
Better Decisions
The tool is useful before powering up, trading, evolving, or transferring. A high attack value can help raids and gym battles. Better defense and stamina can improve staying power. A balanced spread may be useful for collectors. The IV percent gives a simple score. It is not the only value to consider. Move sets, league limits, and real battle roles still matter. Use the output as a guide, not as a final rule.
How Estimates Work
The calculation starts with base attack, defense, and stamina. You can enter those values from any trusted stat table. Next, the form reads the observed CP, HP, level range, and optional stardust cost. The script tests every half level in the selected range. It applies the combat power formula and the health formula. Only matching rows remain. Appraisal filters can narrow the list even more.
Practical Tips
For best results, enter exact CP and HP after healing the monster. Add the stardust cost when you know it. Use the attack, defense, and stamina sliders from the appraisal screen. If the level is uncertain, leave a wider range. A wider range may show more candidates. A narrow range gives cleaner answers. Export the table when you want to compare many catches. The chart helps you see whether the best result is unique or part of a broad cluster.
Privacy and Speed
The page works in one file. It does not need an account. The calculation runs on submission. The chart and downloads are created in the browser. You can save a CSV for spreadsheets. You can save a PDF for notes. This makes batch checking easier during events, trades, raids, and community sessions without extra manual copying.
