Lash Tech Pro is a professional calculator designed for lash extension technicians. Calculate perfect curl type, length mapping, and adhesive conditions for flawless lash applications every time. Choose from six curl types including J, B, C, D, L, and M. Each curl type includes detailed descriptions and recommendations for different eye shapes. Visual curl representations help you make confident decisions for every client. Map lash lengths from 6 to 15 millimeters across five eye zones. Set custom lengths for inner corner, inner, center, outer, and outer corner positions. Default mappings are provided for five common eye shapes including almond, round, hooded, monolid, and downturned eyes. The adhesive calculator tracks humidity from 30 to 70 percent and temperature from 18 to 26 degrees Celsius. Get instant calculations for drying time, expected retention, and recommended glue dot size. Optimal conditions produce four to six weeks retention while poor conditions may result in only two to three weeks. Track unlimited clients with complete profiles. Store eye shape information, natural lash length, sensitivities, and detailed notes for each client. Full appointment history shows service type, lash mapping used, adhesive conditions, and actual retention data. Six service types are available including full set, two week refill, three week refill, removal, mega volume, and hybrid set. Each service tracks duration and includes color coding for quick identification. Add retention data to each appointment to monitor your work quality over time. The app works completely offline with no internet connection required. All client data and settings are stored locally on your device with no cloud sync or external servers. No permissions are needed for camera, photos, location, or contacts. Educational guides are included for curl types, retention tips, and adhesive best practices.
