SpringRithm vs CTE Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
SpringRithm
This app helps users set up coilover suspensions for desired loads and ride heights. It calculates dynamic loads and preload adjustments, even without specialized testing equipment. It also checks for coil binding issues with its spring database.
- Set desired loads and ride heights
- Calculate dynamic spring loads
- Determine preload adjustments
- Check for coil binding
- Access spring database
- Save time on setup changes

SpringRithm is for anyone who has a coilover suspension. With a purchase subscription, SpringRithm allows users to be able to set up their coilover suspensions to their desired loads at their desired ride heights. SpringRithm can assist users who do not have access to a coilover testing machine/Spring Smasher to get their coilovers correctly tuned to get the right loads. SpringRithm not only outputs the dynamic loads that the springs will see in travel, but also tells the user how to preload the coilover nut in order to achieve the set load/loads. For users who do have a coilover testing machine/Spring Smasher, SpringRithm will save tons of time by instantaneously allowing for spring rate and load changes in order to find new setups and figure out how their dynamic loads are changed. SpringRithm also has a built-in database of springs in order to determine if stack setups will coil bind so that users will know if their setup is even theoretically possible. Why guess on what height springs are needed for a setup when you can know!

Verdict
The clearest difference is rating: CTE Calculator at 5.0 against SpringRithm's 4.4. CTE Calculator also leads on in-app purchases (none vs 7) and iOS requirement (13.4 vs 17.0). SpringRithm's advantage is update cadence (every 2 months vs every 15 months) and ratings volume (10 vs 1). On price, ads and device support there is nothing between them.
