## What is Radio Pulsars?

Embark on a celestial journey with Radio Pulsars, an app that transforms your iPhone into a virtual radio telescope for experiencing the captivating world of pulsar astronomy. Pulsars, fascinating remnants of massive stars, are rapidly spinning neutron stars exhibiting incredibly precise periods. Acting as cosmic ‘lighthouses’, pulsars emanate beams of electromagnetic radiation due to ultra-high magnetic fields at their poles.

In Radio Pulsars, you’ll dive into authentic pulsar observations, understanding the complexities of these astronomical phenomena. Pulsars, with their distinct pulse profiles, are like fingerprints of the universe. The app showcases 85 pulsars, including 26 glitching ones, providing a diverse collection of cosmic wonders.

Explore iconic pulsars like PSR J1921+2153, the first detected in 1967, PSR J0534+2200 located in the Crab Nebula, and PSR J0835-4510, the brightest known pulsar. Witness the stability of PSR J0437-4715 and the uniqueness of PSR J0332+5434, the brightest pulsar in the northern sky. Marvel at the extraordinary double pulsar system, PSR J0737-3039, and the pulsar-neutron star duo, PSR J1915+1606.

Radio Pulsars offers a comprehensive exploration for these cosmic marvels, providing an engaging and educational experience for astronomy enthusiasts. Immerse yourself in the captivating world of pulsar observation and unravel the secrets of the universe!

Please note Radio Pulsars now only supports iPhone and does not support iPad.

### 2/5 — Awkward

*2025-10-27*

The interface performs well and is responsive, but seems to be focused on the challenge of lining up the phone with the pulsar, which is somewhat challenging but not rewarding. The details of any pulsar are confusing, and I would like to switch between them to compare the data to understand how they are different, but switching is such a tricky process there’s really no way to switch back and forth. An interesting topic of focus, but I sense too much focus on the technology and not enough on making the experience worthwhile..

**Developer response:** Thank you SO much for the review! I’m responding immediately after I saw your review. But it’s late —— I’m SORRY!

Perhaps parts of the challenging are from the wobble of the sight. It is bad. It is just I couldn’t find a way to reduce/remove it when I was first developing the app. But I really want to simulate real observations. I will investigate if there is any way to reduce/remove it. This will be one of the points for the next update. Further reduction of the challenging may require changes to the interface. I will think about this carefully.

To compare pulsars is a big idea, I think this would be the point for the next major update.

I got much work to do at the moment; I schedule to start to work on these updates next April —— Many thanks for understanding!

Thank you very much for the review again!

Sincerely yours,
Meng Yu
