I have a requirement for a custom calculator App for iPhone and iPad. Needs to be compatible with latest Apple models.
1. Logo screen (splash screen)
2. customisable field names - example - field1=mass, field2=acceleration, field3=force
3. enter formula screen - example - field3= field1 * field2 (which makes force=mass * acceleration in backend)
4. main screen to enter values: user will enter mass and acceleration values and output is force.
5. many formulae to be stored in memory and user selects which formula to enter values.
Send me any references of your previous work. Custom design also needed.
