Read full descriptionHide full description
The "Rollei Studio" app enables you to set and control certain Rollei radio transmitters and thus lightning bolts, e.g. in power, synchronization modes and flash modes. Selected Rollei LED permanent lights can also be operated directly via the app and their output, color temperature, light effects etc. can be varied. All light sources can be divided into groups and thus controlled in a targeted manner. This allows you to operate your complex lighting setup flexibly and without great effort.

Verdict
The clearest difference is in-app purchases: Rollei Studio at none against ND+Timer's 1. Rollei Studio also leads on iOS requirement (12.0 vs 15.6). ND+Timer's advantage is update cadence (every 2 months vs every 13 months). On price, ads and device support there is nothing between them.
