FAQ — Vape Tool

No change is needed. When you use “Continue with Google/Facebook/etc.” (OAuth), you never enter your password in our app. The provider (e.g., Google or Facebook) verifies you and confirms to us that you own the account (e.g., [email protected]). We rely on that provider’s verification and do not store your third-party password.

If you synced with the Cloud, your data is safe. If you didn’t, the app creates an automatic local backup on each exit:

/storage/emulated/0/VapeTool/

You can reinstall the app from https://vapetool.app/download_apk, then go to Settings → Restore.

Sign in to your Cloud account and your Pro status should restore automatically. If you never used Cloud, we can activate it manually. Please email proof of purchase to [email protected] from the same email you used to buy Vape Tool Pro on Google Play.

Apple has banned apps related to nicotine, tobacco, vaping, or cigarettes from the App Store. This means our app — even with restricted functionality — can no longer be published or updated on iOS.

In the past, we released a limited version called Coil Builder (the name “Vape Tool” was taken and the word “Vape” is prohibited). We also had to hide features like Liquid Blender and Cloud, and avoid any vaping references to meet Apple’s requirements. That allowed us to release the first and only iOS version at the time.

Since Apple’s policy change, existing vaping-related apps on the App Store are frozen (no updates), and new ones cannot be published. To address this, we built a web app that works on any device, including iOS.

If the “Restore” button doesn’t work, the App Store still recognizes your purchase. Sign in with the same Apple ID you used to buy Pro. Open the Pro purchase screen and proceed as if buying again — the App Store should detect your previous purchase and restore it at no charge.

Due to Apple’s policy, we can’t ship fixes or updates to the iOS app.

We know the Custom Type feature can be confusing. We’re working on clearer UX, more predefined builds (e.g., zipper), and better performance for complex builds.

Example: Zipper Coil

Example: Fused Juggernaut

1. (Recommended) Sign in to Cloud on both versions and let them sync.
2. Via backups:
   1. In the Free version: Settings → Backup recipes → BACKUP
   2. In the Pro version: Settings → Backup recipes → RESTORE

The “Consume” action helps you track remaining amounts of flavors. When you mark a recipe as consumed, the app subtracts the used amounts from your Flavors Collection.

Example

Flavors Collection before consume

• …
• Apple (TPA) — 10 ml
• Blueberry (TFA) — 10 ml
• …

Recipe uses:

1. Apple (TPA) — 1 ml
2. Blueberry (TFA) — 2 ml

Flavors Collection after consume

• …
• Apple (TPA) — 9 ml (10 ml − 1 ml)
• Blueberry (TFA) — 8 ml (10 ml − 2 ml)
• …

The Pro version gives you access to numerous predefined coil types plus a Custom Type builder to create any coil you need. (Note: iOS is limited due to App Store restrictions.)

Find the optimal power range (“sweet spot”) for your coil build quickly and accurately.

Track remaining amounts of your flavors by consuming them each time you prepare a new batch.

Compare batteries side by side and find the best option for your setup.

See all e-liquids that use a given flavor and get notified when a flavor is running low.

To keep your battery safe, don’t exceed its maximum power output. Avoid using coils with resistance lower than your battery’s specified minimum resistance.

A home screen widget for quick calculations of resistance, power, voltage, and current.

In addition to predefined wire materials, add your own and use them in coil calculations.

See the wire length required for your build so you cut only what you need.
