We are glad to present you a new application GTOBase
GTOBase is GTO solutions database and hand history analyzer. Until the end of June, you can purchase an early user subscription with a 50% discount for $75 per month (the discount will apply to the first two months of subscription)
Currently (22.06.2020) only HU spots from the Spin&Go discipline are available (also relevant for HU Hyper-Turbo). In the near future (June-July), all kinds of 2-way situations from 3-max will appear. Later GTO solutions will appear for other poker disciplines.
More detailed info and video instruction could be found on the GTOBase page in the "Tools" section.
