## Description

Support for the latest products

Control your heating products conveniently from your smartphone using the free app. Whether it be heat vests, socks, gloves, vests, pant or soles - with the Lenz heat app, the heat setting of the lithium packs can be regulated quickly and without complications. Additionally, it provides an overview of the current charge level of all the lithium packs. This is perfect if the heating product is under several layers of clothes.

Advantages of the app:

EACH LITHIUM PACK CAN BE CONTROLLED SEPARATELY
Each of the connectible lithium packs can be set to a different heat level so you get just as much heat as you need everywhere. 

INTERVAL FUNCTION
Heating and pause times can be set individually with the interval function, which extends the lithium packs’ lifetime. 

LED-OFF: 
If the LEDs glow through a thin item of clothing, they can be deactivated. The heat output remains set as defined in the app.

ORDER FOR THE LITHIUM PACKS
Coloured rubber rings are delivered with the lithium packs. These help you to distinguish entire “battery pairs” from each other or to distinguish the batteries that are purposely to be used on the left and on the right. You can assign the colour of the rubber rings to the batteries in the app. 

LED SYSTEM:
The Lenz LED system 1.0 can also be controlled with the app. Different colours, lighting modes and brightness levels can be set.

Smartphone requirements for running the Lenz heat app:
- iOS 13.0 or above
- Bluetooth 4.0 (SMART ready)

## Review summary

Reviews are mixed. Users note clear improvements over the initial app and, when it works, smooth operation. However, many report reliability problems: frequent crashes, random heating shutdowns, and settings not persisting. Battery visibility is poor (no clear percentage) and batteries can drain, with calls for a complete shutdown option. There is widespread demand for Apple Watch support. Connection and pairing issues persist (iPhone vs iPad, heat-pack connections, single-packs). Privacy concerns appear in at least one review. Overall, the app has progress but remains unstable and incomplete.

### Pros

- Significant improvement over the initial app with smoother operation.
- When functioning, the app runs fairly seamlessly and allows effective heat control.
- The newer app versions show notable improvements that some users appreciate.

### Cons

- The app crashes frequently and is unstable.
- It randomly shuts off heating or resets to zero; settings are not reliably remembered.
- Battery management issues: lacks a battery percentage indicator, can't completely shut off batteries, and drains battery.
- No Apple Watch app / lack of watch integration.
- Connectivity/ pairing issues: inconsistent pairing across devices (iPhone vs iPad), trouble connecting to heat packs, and limitation to one battery pack.
