7. The system of claim 1, wherein the server is further configured to perform computational analysis.

8. The system of claim 7, wherein the computational analysis comprises an analysis of degree of erythema of a treated area of skin and surrounding skin tissue.

9. The system of claim 7, wherein the computational analysis comprises an analysis of treatment progression comprising size and severity of the skin condition or of a disease.

10. The system of claim 1, wherein the server is further configured to determine an initial phototherapy dose based on a user skin type or susceptibility to erythema of a user of the phototherapy device.

11. The system of claim 1, wherein the phototherapy device comprises a hand-held phototherapy device.

12. The system of claim 1, wherein the phototherapy light source is configured to emit a light comprising a UVB wavelength in the range of 300-320 nm.

13. The system of claim 1, wherein the phototherapy light source comprises a light emitting diode (LED).

14. The system of claim 1, wherein the patient computing device comprises a smartphone, the signals comprise wireless signals, the transmitter comprises a wireless transmitter, and the receiver comprises a wireless receiver.

15. The system of claim 1, wherein the patient computing device is further configured to present an interface allowing the patient to capture an image of a treated area of skin and the surrounding skin tissue.

16. The system of claim 1, wherein the patient computing device is further configured to present an interface providing guidance to the patient for operation of the phototherapy device.

17. The system of claim 1, wherein the patient computing device is further configured to present an interface providing a treatment schedule, treatment reminders, directions for how to use the phototherapy device, or any combination thereof.

18. The system of claim 1, wherein the skin condition comprises psoriasis, vitiligo, or eczema.

19. A method for treating a skin condition with phototherapy, the method comprising:

a) transmitting, by a patient computing device, a first signal to a phototherapy device comprising a phototherapy light source, the first signal enabling operation of the phototherapy device according to one or more conditional prescription parameters;

b) activating, by the patient computing device, the phototherapy light source;

c) transmitting, by the patient computing device, a second signal; and

d) receiving, by a server, the second signal, wherein the server is configured to communicate with the patient computing device.
