Unless Harmony OS has Android app compatibility then the lack of apps will put it in the viscous circle of no developers port their apps due to the lack of an install base and customers are dissatisfied with it due to the lack of apps. We have seen that exact problem with Windows phones and Blackberry, and Blackberry did have limited Android app support on their later phones.
With its low hardware requirements Harmony OS could become a option for feature phones where the lack off apps isn't an issue, but what value will it have for manufactures to switch to that over using KaiOS which has gained good traction in that arena already.
