Atypical Athletics put photocells in the palm of your hand. There is a finally a professional timing app designed by sports and conditioning professionals.

Photocells get the maximum performance out your iPhone’s technology to allow your device, and others, to work as a system of photoelectric cells, maintaining all of photocell technology’s advantages while eliminating the drawbacks. Not to mention doing so at a fraction of the cost.


You can use Photocells with a single device to create a timing gate and train short sprints, as well as laps to a circuit and agility tests. If you have training partners or more than one device, you can add as many timing gates as you want, creating as many training possibilities as you can imagine: create intermediate timing gates to calculate your acceleration capacity, or value your performance in key points of an agility circuit.

Photocells will change the way you evaluate your performance and plan your training, regardless of whether you are professional or amateur, individual or team athlete.


If you dreamed of training with a professional timing system that neither you nor your club could afford, finally you have it at your fingertips. You can get Photocells for less than a professional stopwatch worth. In addition, it is enough to have an active photocells subscription on a device. Then, any device with the free version of Photocells can be connected as a secondary gate.

Photocells cost less than a professional stopwatch, and it is enough to have an active Photocells subscription on one device. Then, any device can be connected for free as a secondary timing gate.

Photocells is a fully automatic timing app. Place your iPhone on a stable surface, adjust the position of the gate to your liking and concentrate on your workout. Photocells takes care of the rest. Then, you can comfortably export the results of the session to visualize them or view them in a spreadsheet.

Only a data connection is required on the devices being used for Photocells to run. Forget the distance limits imposed by cables or Bluetooth connection on commercial photoelectric devices, Photocells is easy and simple to use. And remember, you can connect as many devices as you want for free.
