Comments on OnStep Controller2 for Android

★★★★★ vzr · Oct 12, 2021

This app is the greatest advantage Instep controller by far. It is an effective replacement for both Smart Hand Controller and Smart Web Server (Wemos) because it works with internal Bluetooth if ESP32S is used in build. Also, there are other perks like polar alignment correction and smart tracking correction... Only missing tool is polar hour angle calculator

★★★★★ Peter Baldwin · Sep 19, 2021

Converted my eq3-2 to a goto mount amazing work Howard, Khalid, David and all involved in this awesome open source project. Thanks guys!

★★★★★ Carlos Ferraz · Jan 5, 2017

It's an incredible work! This app, with the open source Instep project, works really nice. I converted my eq3-2 with default motors to a goto spending less than 70 U$D (about 200 BRL). My slew rate is just about 50x thanks to the motors only, but I don't care. I can wait a minute or two!

★★★★★ Murat Isik · Jul 26, 2019

Having such an app to complement an open-source telescope controller software is of unmatched value. I am a true believer in Instep.
