The story

Why I made it

Power Stones don't come cheap in The Tower. Spending resources efficiently actually matters here, so I built this to stop guessing: load your export, see exactly where you stand, and find the cheapest combination of levels and substats that actually gets you to permanent uptime.

The details

How it came together

Built with thetowersdk to read a Chrono Field loadout straight from a player's tool_export.json. Everything runs client-side in the browser; the file is never uploaded anywhere.

Load your export

Choose your tool_export.json file to check your permanent uptime status and plan the cheapest way to improve it. Nothing leaves your device.

To create it in The Tower, tap your Player ID five times the first time, then go to Settings → Toggles → External Tools Export → Manual Export. On Android, the file lands in Android/data/com.TechTreeGames.TheTower/files/.

Choose your export file to get started.
