Craftsmen in the construction industry spend a lot of time preparing individual offers. In particular, the fact that the measurement of the object and the preparation of the offer take place at different locations means that a great deal of time is required for the preparation of meaningful sketches on site and the subsequent transfer into a professional measurement. With MasterPlan, a sufficiently good survey of an object can be created easily without additional equipment, which offers a decisive time advantage. Since MasterPlan also enables the automated creation and sending of an initial cost estimate to the customer directly on site, there is a real added value for the target group (e.g. painters, floor layers, installers, etc.). Get MasterPlan Pro and enjoy the following benefits: - Unlimited number of materials - Unlimited number of projects - Unlimited number of rooms - Unlimited number of additional areas - Cost estimate via email - Cloud sync between your devices - No ads Please review our Terms of Use (https://www.masterplan.app/6-2-terms-of-use) and Privacy Statement (https://www.masterplan.app/7-2-privacy-statement) for further information.

Verdict
The clearest difference is in-app purchases: 21energy at none against MasterPlan AR's 1. 21energy also leads on update cadence (fortnightly vs every 3 months). MasterPlan AR's advantage is review sentiment (33% vs 17%) and iOS requirement (11.4 vs 15.0). On price, ads and device support there is nothing between them.
