Recommended! ### 5/5 — Bike gear *2014-12-29* Must for bikers, whenever I need to know the perfect gear ratio I use this app ### 5/5 — Amazing app *2014-12-29* It's very useful and convenient. :) ### 5/5 — Great app *2014-12-29* It’s very helpful for me when I need to calculate the time or practices for biking. Thanks! ### 5/5 — Great app *2014-12-28, version 1.1* Cool app, really informative! ### 5/5 — Long awaited useful app *2014-12-24, version 1.1* This app is long awaited, I wish I had this when I was racing on gear restrictions . A quite simple but essential app for any cyclist ! ## Most critical reviews (10 lowest-rated) ### 1/5 — Unreliable *2024-06-01, version 1.5* App was good in the beginning but after a week it kept crushing and never worked again after that! Don’t waste your money. ### 3/5 — Tire Size Limitation *2022-08-21* It would be better if I could select 700x42 tire size. Without, it’s of limited value to me. ### 4/5 — Update *2020-09-08, version 1.5* Pls update app to accommodate 52 tooth cassette option...SRAM Eagle. Cheers. ### 4/5 — Great app but falls short for current drivetrains *2020-07-13* Need to update to allow for Shimano and SRAM 51t and 52t cassettes. ### 5/5 — Mandelbrotdog *2021-08-04, version 1.5* Excellent app! Keeps it simple but with exceedingly good taste. ### 5/5 — Indispensable *2020-05-24, version 1.5* A brilliant app. Well worth the price recommended! ### 5/5 — Multi-Bike Register *2020-05-20* Having bikes with multiple setups, the app allows me to look at specs for a certain application without looking at the rig. I can update the app when I change bike gearing for most up-to-date info. It allows me to see most if not all parameters associated with the gearing; hence, I can choose the bike for the job quickly! ### 5/5 — Great app especially for multi-geared riders *2018-10-05* I really love this app and all the nifty functions that it offers. You can create custom charts of your multi-geared drivetrain that will give you an idea of the various ratios your bike has. I would recommend this to novice riders as it is very easy to illustrate how the desired gear ratio can be replicated without having to engage the “big-big” or “small-small” combo. A couple of suggestions to improve this app: 1. Add an extra digit after the decimal to the gear ratio displayed in the chart table 2. Add skid patch calculation on the home screen (bonus if it offers ambidextrous skidding). This would make the app attractive for fixie riders too ### 5/5 — Perfect calculator for bike *2018-09-11* Nice and simple to use. Information available in single view. I love to challenge myself using app.👍 ### 5/5 — Great app! *2016-07-18* I wrote to the developer, asking that he add cassette cogs up to 50 teeth, and he did it within a week. Thanks! ## Most praised reviews (4 highest-rated) ### 5/5 — Works perfect to calculate gear changes *2016-07-17* Very happy with how this app works. I use it to calculate gear changes with advanced modern 1x drivetrains as well as how tire size effects gear range with all the tire width changes like wider modern bikes that are all road and gravel bikes. ### 5/5 — Handy as *2015-09-12, version 1.2* If your trying to pace yourself and know a little bit more about the gears then Themis helps a lot. ### 5/5 — very helpful app *2015-01-05* I am using this app daily very good app to learn biking ### 5/5 — Awesome app *2015-01-02* Very good app to calculate Bike gear, i can even save results to compare multiple bikes --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
