## What is GO IV?

GO IV reads CP, HP, and power-up stardust from a summary screenshot, estimates possible IV sets and level on your device, and analyzes PvP ranks.

Results show the IV range, a next step, and buddy boost.

PvP analysis:
• See ranks and stat products for Little Cup, Great, Ultra, and Master League at every evolution stage
• Tap an IV set to see its best level, CP, and the Stardust, Candy, and XL Candy needed to get there
• Copy a nickname in one tap and paste it in the game
• Saved entries show their PvP rank

Browse base stats, types, evolution, and CP by level. In the Settings tab, set the level cap, IV floor, default league, nickname format, and trainer level. History and favorites stay on this device. Screenshots are not saved.

One summary at a time. If CP, HP, or stardust is missing, the app shows an error and does not save a history entry.

Faster, smoother IV calculation

• The results page now works out IV ranges, IV percentages and evolution stats once, so renaming, moving the level slider and toggling Buddy Boost feel smoother
• Pokédex and move data load only once, so results, saved items and the Pokédex open faster
• Changing the level no longer collapses an expanded IV table

Regional forms

• Adds 56 regional forms (Alolan, Galarian, Hisuian and Paldean), so Pokémon such as Galarian Meowth now get correct IVs
• Scans use the type shown in the screenshot to pick the form; when it can't tell, the results page lets you choose
• The Pokédex, manual entry, saved items and scan history show and keep the form, and evolutions follow the form

Other

• Performance and stability improvements
