### 1/5 — Support Discontinued

*2026-04-22, version 3.7.2*

This app hasn’t been updated 3 years, and most of the help articles you’ll find online about with smart home integrations like Alexa and Apple are from 2022. As users are seeing increasing issues with the app features (failed connections, freezing, unable to access support), it’s clear the company has no plans to make further improvements to this product line or interface.

The company (Lumiman) no longer seems to sell their smart bulbs in the States, even on Amazon. Essentially, any Americans like myself who purchased these smart bulbs years ago are SOL.

My Lumiman bulbs are basically just regular lightbulbs now and this app has been consistently unreliable. Looking forward to switching these final few devices over to Phillips Hue to have a cohesive system in my home soon and be done with the PlusMinus app once and for all.

### 5/5 — Mrs. Molly

*2026-04-15, version 3.7.2*

Awesome

### 1/5 — Trash

*2026-03-10, version 3.7.2*

Freezes, can’t click around, uninstalled 10x still doesn’t work, can’t contact support, can’t use my lightbulbs… trash app, trash devs, trash products.

### 4/5 — Lights

*2026-02-14, version 3.7.2*

The app has been good for last few years. But lately, say I want to turn the light green it’ll be red and won’t switch to green when on green color.

### 1/5 — Get a refund asap

*2025-11-22, version 3.7.2*

Not worth the hassle, sometimes it will work perfectly fine and the next day everything will just break on its own.

### 1/5 — Does not work with Alexa

*2025-11-09, version 3.7.2*

The Alexa Skill can not connect anymore; can operate the plug with their app, not Alexa.

### 1/5 — Won’t sync with Alexa

*2025-11-01, version 3.7.2*

All my Alexa automation routines are useless now. I used to have all my exterior lights turn on and off with the sunset/sunrise. Now I get home at night and it’s completely dark. Not cool guys. Please fix this issue.

### 1/5 — Stopped working

*2025-10-30, version 3.7.2*

Life had this app
Since 2020. It stopped working with Alexa.

### 2/5 — Suddenly won’t work

*2025-10-28, version 3.7.2*

Suddenly my lightbulbs that I’ve been using for over a year won’t work with my Alexa. I can’t link them again. I can only control them using my phone. Pretty much makes them useless.

### 1/5 — FIX YOUR APP

*2025-10-28, version 3.7.2*

Worked well with Alexa integration for YEARS until it stop working. Tried disabling the app and reconfiguring the lights, only to be met with “we are unable to enable the skill at this time.”

Waste of money and time. SMH.
